In generalization tests, a number of benzodiazepines (alprazolam, chlordiazepoxide, midazolam, lorazepam) and the barbiturate pentobarbital substituted completely, while zolpidem and abecarnil substituted partially for alprazolam. In contrast, no significant degree of generalization to the antidepressants imipramine and fluvoxamine and the putative antidepressants buspirone and flesinoxan was found. In antagonism studies alprazolam could be antagonized (almost) completely by flumazenil, partially by pentylenetetrazole, but not by methyl 6, 7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM), N-methyl-beta-carboline-3-carboxamide (FG-7142) and picrotoxin.

Drug and nondrug interventions used in treating nicotine dependence are reviewed. Tobacco use is the leading preventable cause of death in the United States. Risks of smoking-related disease and death decline sharply when smokers quit, but 26% of Americans continue to smoke. Most smokers find it extremely difficult to quit smoking because of their nicotine addiction. Nonpharmacologic interventions used to promote smoking cessation include behavioral therapy, setting a specific date for quitting, receiving advice to quit from a health care professional, follow-up visits to review progress, self-help approaches, group counseling, filtration devices, hypnosis, and acupuncture. The efficacy of these approaches ranges from substantial to almost nil. The only pharmacologic agent with FDA-approved labeling for use in smoking-cessation therapy is nicotine. When used in conjunction with appropriate nonpharmacologic interventions, nicotine-replacement therapy roughly doubles the rate of quitting obtained with placebo. Nicotine-replacement therapies consist of nicotine transdermal (patch) systems and nicotine chewing gum. The nicotine patch is the first-line replacement therapy because it is effective when accompanied by only minimal (as opposed to more intensive) nonpharmacologic interventions and because it is easier to use and comply with than gum. Clonidine, antidepressants, and buspirone require further study to determine what role, if any, they should play in the treatment of nicotine dependence. The stages of smoking cessation are precontemplation, contemplation, action, and maintenance; interventions are selected on the basis of the stage the smoker is in. Nicotine dependence is difficult to treat, but there are aids that boost a smoker's chances of quitting. Nicotine patches and chewing gum offer the most effective pharmacologic options, especially when combined with behavioral interventions and counseling.

The present study developed a new protocol to assess shock sensitivity in rats. Male Wistar rats were subjected to footshock stimuli ranging from 0 to 1.6 mA (0.1 s) in a startle apparatus and startle responses elicited by shocks were measured. Acoustic stimuli (95, 105, or 115 dB) were dispersed within the shock series serving as a control measurement of motor performance. Results indicated that the magnitude of shock startle responses significantly increased with the shock intensity in a linear trend. Morphine (8.0 mg/kg) and buspirone (1.0, 2.5, or 5.0 mg/kg), both of which possessing analgesic effects, depressed shock startle but had no such effect on acoustic startle. The effect of morphine was readily reversed by pretreatment of naloxone (1.0 mg/kg). To investigate the neural basis underlying this response, radio-frequency lesions of various structures implicated in processing of nociceptive or aversive information were undertaken. Lesions of the ventroposterior thalamic nucleus, insular cortex, or amygdala decreased startle reactivity to electric shocks but not to acoustic stimuli. Lesions of the anterior cingulate gyrus or medial prefrontal cortex, while altered the reactivity to acoustic stimuli, had no effect on the shock-elicited startle. These results suggested that the amplitude of startle in response to electric shocks provide a quantitative measurement of shock sensitivity within an extended range of stimulus intensities. Performing this response may engage the the central nociceptive pathway.

Selective serotonin reuptake inhibitors (SSRIs) are known to cause sexual dysfunction, such as decreased sexual motivation, desire, arousal, and orgasm difficulties. These SSRI-induced sexual complaints have a high prevalence rate, while there is no approved pharmacological treatment for SSRI-induced sexual dysfunction. It is hypothesized that a polymorphisms in the androgen receptor gene, encoded by the nucleotides cysteine, adenine, and guanine (CAG), influence the effect of testosterone on sexual functioning. In an explorative, randomized, double-blind, placebo-controlled, crossover study we investigated the possible effects of sublingual testosterone combined with a serotonin (5-HT)1A receptor agonist, and of sublingual testosterone combined with a phosphodiesterase type 5 inhibitor (PDE5-i) on sexual functioning in women with SSRI-induced sexual dysfunction. Furthermore, we did an exploratory analysis to assess if the CAG polymorphism influences this effect. 21 pre- and postmenopausal women with SSRI-induced sexual dysfunction participated and underwent the following interventions: a combination of testosterone (0.5 mg) sublingually and the PDE5-i sildenafil (50 mg) and a combination of testosterone (0.5 mg) sublingually and the 5-HT1A receptor agonist buspirone (10 mg). The results show that women who use a low dose of SSRI and have relatively long CAG repeats report a marked improvement in sexual function in response to both treatments compared to placebo. This explorative study and preliminary results indicate that in women with SSRI-induced sexual dysfunction, a combination of testosterone sublingually and a PDE5-i or testosterone sublingually and a 5-HT1A receptor agonist might be promising treatments for certain subgroups of women with this condition.

Chronic exposure to mild unpredictable stress has previously been found to depress the consumption of palatable sweet solutions, and this effect was reversed by chronic treatment with a variety of antidepressant drugs. The present study reports three experiments examining the effects in this model of further antidepressant agents, a number of non-antidepressants, and some compounds of indeterminate clinical status. Male Wistar rats were exposed sequentially to a variety of mild stressors, which continued throught the experiments. Drug treatments commenced after 3 weeks of stress, by which time intake of a 1% sucrose solution (measured in a 1-h weekly test) was significantly depressed. No drug effects were seen after 1 week of treatment. Normal levels of sucrose drinking were seen following chronic (3-5 weeks) of treatment with the antidepressants imipramine (10 mg/kg per day), brofaromine (20 mg/kg per day), and buspirone (5 mg/kg per day). Positive effects were also seen following chronic treatment with atropine (1 mg/kg per day) and mepyramine (5 mg/kg per day). d-Amphetamine (1 and 3 mg/kg per day), the neuroleptics haloperidol and chlorprothixene (1 mg/kg per day), and morphine (administered at doses rising to 110 mg/kg per day) were ineffective; amphetamine (3 mg/kg) and morphine decreased sucrose intake in control animals. No inferences can be drawn from the effects of atropine and mepyramine, which are of indeterminate clinical status; data from the other seven agents tested support the hypothesis that the chronic mild stress model responds appropriately to antidepressant and non-antidepressant agents.

Baboons and rats were trained to discriminate lorazepam and pentobarbital in a food-maintained two-lever drug vs. no-drug discrimination procedure. Previous research showed that benzodiazepines, but not barbiturates, occasioned drug lever responding in the lorazepam-trained animals. Lorazepam and six nonbenzodiazepines that have been proposed as anxiolytics (CGS 9896, CL 218,872, PK 9084, zopiclone, buspirone and 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol) were studied in test sessions in which responding on either level produced food. Of the nonbenzodiazepine compounds studied that displace 3H-benzodiazepines in vitro, CL 218,872 and zopiclone occasioned drug lever responding in all animals; PK 9084 did not occasion drug lever responding in any animal; and CGS 9896 did not occasion drug lever responding in lorazepam- or pentobarbital-trained baboons or in lorazepam-trained rats, but did so in the pentobarbital-trained rats. Buspirone, a nonbenzodiazepine anxiolytic with prominent dopaminergic activity, and 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol, a gamma-aminobutyric acid agonist, also did not occasion drug lever responding in either baboons or rats, regardless of training drug. Time course studies in baboons with CGS 9896, PK 9084, 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol and buspirone did not reveal delayed onset of drug stimulus generalization. Some differences in potency as a function of route of administration were found with CL 218,872, zopiclone and buspirone. The discriminative stimulus effects of lorazepam, CL 218,872 and zopiclone were antagonized by the benzodiazepine receptor antagonist Ro 15-1788. It is concluded that the discriminative stimulus properties of these nonbenzodiazepine compounds thus do not co-vary with their antipunishment effects, with their clinical efficacy as anxiolytics or with benzodiazepine receptor binding.

The United States Pharmacopoeia high-performance liquid chromatographic (HPLC) assay method of buspirone is not able to discriminate buspirone from its degradation products. The purpose of this work is to develop a sensitive, selective, and validated stability-indicating HPLC assay for the analysis of a buspirone hydrochloride in a bulk drug. Buspirone HCI and its potential impurities and degradation products are analyzed on an Ultrasphere C18 column heated to 40 degrees C using a gradient program that contains monobasic potassium phosphate buffer solution (pH 6.9) and acetonitrile-methanol mixture (13:17) of 35% for 5 minutes, then increased to 54% in 5.5 minutes. The samples are monitored using a photo-diode array detector and integrated at 244 and 210 nm. The stress testing of buspirone HCI shows that buspirone acid hydrochloride is the major degradation product. The developed method shows a separation of buspirone degradation product and its potential impurities in one run. The stability of buspirone HCI is studied under accelerated conditions in order to provide a rapid indication of differences that might result from a change in the manufacturing process or source of the sample. The forced degradation conditions include the effect of heat, moisture, light, acid-base hydrolysis, sonication, and oxidation. The compatibility of buspirone HCI with some pharmaceutical excipients is studied under stress conditions. The linear range of buspirone HCI is between 5 and 200 ng/microL with a limit of quantitation of 2.5 ng/microL. The intraassay percentage deviation is not more than 0.38%, and the day-to-day variation was not more than 0.80%. The selectivity, repeatability, linearity, range, accuracy, sample solution stability, ruggedness, and robustness show acceptable values.

After 21 days of treatment with diazepam (2 mg/kg/day IP) rats were tested 24 h after the last injection in the social interaction and elevated plus-maze tests of anxiety. Compared with control-treated rats, they showed significant decreases in social interaction, in the % numbers of entries onto open arms of the plus-maze and in the % of time spent on the open arms, indicating an anxiogenic response on withdrawal from diazepam. Buspirone (200 micrograms/kg SC) significantly increased social interaction in diazepam withdrawn rats and in the plus-maze also this dose significantly reversed the anxiogenic effects of diazepam withdrawal. Buspirone (400 micrograms/kg SC) was without effect in the plus-maze, but buspirone (800 micrograms/kg SC) significantly decreased the % of time spent on open arms in control-treated rats, indicating an anxiogenic effect. In the social interaction test buspirone (800 micrograms/kg SC) was without significant effect. The contrasting effects of the 200 and 800 micrograms/kg doses are discussed in terms of the pre- and post-synaptic actions of buspirone. The findings are consistent with earlier proposals that the increased anxiety during benzodiazepine withdrawal is at least partly caused by an increased release of hippocampal 5-HT.

Patients suffering from anxiety disorders show increased fear when encounter a novel environment. Rodents, placed in new environmental context may respond either with increased novelty seeking (active), or enhanced anxiety (passive coping style), which may depend on the trait anxiety of the animal. Here, the connection between the initial level of anxiety and the behavioral responses in a novel environment was investigated. Two inbred mouse strains having either high- or low-anxiety related behavior (AX and nAX) were exposed to elevated plus maze (EPM), a standard test for assessing anxiety level, for 8 consecutive days. The initial anxiety level was modulated by chronic treatment with buspirone (bus) treatment, a clinically effective anxiolytic, using 2.5mg/kg and 5.0mg/kg doses. Both strains showed a gradual decrease of open-arm exploration, which was not prevented by bus treatment. Another cohort of animals was exposed to EPM for 2 days, and then we changed to blue light illumination and used a different cleaning substance with citrus odor (context change, CC). It was found that upon CC AX mice exhibited increased, while nAX mice showed decreased anxiety. Bus in 2.5mg/kg changed the coping strategy from passive to active exploration after CC in the AX mice; however, the same treatment rendered nAX mice passive upon CC. Bus in 5.0mg/kg failed to alter the overall coping style in the novel environment of both strains. These results suggest that these mouse lines use different coping strategy in novel context, which can be changed with bus treatment.

In a double-blind placebo-controlled trial, we evaluated the efficacy of the combination of sertraline and buspirone plus cognitive-behavioral treatment to promote tobacco abstinence in individuals referred to a chemical dependency clinic. Ninety eight individuals 18-65 years of age were randomized to placebo or sertraline 25 mg/day for 2 days, followed by 50 mg from day 3 to 90, and buspirone 5 mg three times a day for 7 days, and 10 mg from day 8 to 90. The rate of continuous abstinence at the 26th week of follow-up, informed by the patient, was 43.5% in the active treatment group and 17.3% in the control group (p = 0.01). The odds ratio for continuous abstinence for the intervention group was 4.74 (95% CI 1.50-14.55) (adjusted for smoker households and number of cognitive sessions). Nicotine withdrawal symptoms were common in both groups (98.7% vs. 95.5% p = 0.37). The combination of sertraline and buspirone with cognitive-behavioral therapy was more effective than placebo and cognitive-behavioral therapy to promote smoking cessation.

The effects of the pyrimidinyl-piperazines buspirone, gepirone, ipsapirone and their common metabolite 1-(2-pyrimidinyl)-piperazine (PmP) as well as of 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) and L-5-hydroxytryptophan (L-5-HTP) were investigated in Montgomery's conflict test--an animal anxiety model based on the animal's inborn urge to explore a new environment and its simultaneous fear of elevated, open spaces. Subcutaneous buspirone (32-128 nmol/kg), gepirone (32-128 nmol/kg), ipsapirone (32-512 nmol/kg) and 8-OH-DPAT (50-200 nmol/kg), as well as intraperitoneal L-5-HTP (56 mumol/kg) produced anxiolytic-like effects. However, at higher doses the magnitude of these effects decreased and overall the dose-response curves displayed inverted U-shapes. The highest doses (2048 nmol/kg) of buspirone and of gepirone even decreased responding below control levels, possibly in part due to concomitant sedation/motor impairment. After L-5-HTP (448 mumol/kg) and PmP (512 nmol/kg) anxiogenic-like effects were observed. The results indicate that anxiolytic- and anxiogenic-like effects of drugs affecting central serotonergic neurotransmission can be obtained in a sensitive rat anxiety model which neither involves consummatory behavior nor punishment. The anxiolytic-like effects of these compounds may be due to their 5-HT1A agonistic properties. Moreover, the present data may provide support for a possible reciprocal association of presynaptic 5-HT1A receptors vs. postsynaptic 5-HT1A as well as 5-HT2 receptors with regard to anxiety.

In vitro binding assays with 125I-[8-methoxy-2-[N-propyl-N-(3'-iodo-4'-hydroxyphenyl)-propionamido -N'- propylamino] tetralin] (125I-BH-8-MeO-N-PAT), a 125I-labeled derivative of the potent serotonin (5-HT) agonist 8-hydroxy-2-[di-n-propylamino]tetralin [( 3H]-8-OH-DPAT), showed that this compound recognized specific sites with nanomolar affinity for 5-HT and 5-HT1A ligands such as spiroxatrine, ipsapirone, buspirone and gepirone in rat hippocampal membranes. Comparison of the binding characteristics of 125I-BH-8-MeO-N-PAT with those of [3H]-8-OH-DPAT revealed striking similarities: at the hippocampal level, both binding sites exhibited nanomolar affinity for their respective ligands and the same Bmax; their pharmacological profiles defined by the inhibition of each bound ligand by a series of 26 serotonin, dopamine- or norepinephrine-related agonists and antagonists were identical; and their regional distributions examined by membrane binding assays and autoradiography of labeled brain sections were highly correlated. These observations indicate that 125I-BH-8-MeO-N-PAT is the first 125I-reversible ligand for the selective labeling of 5-HT1A sites in the rat central nervous system.

Disturbances in behavioral inhibition are key features in several neurological and psychiatric disorders, such as attention-deficit/hyperactivity disorder, Parkinson's disease and substance use disorders. Therefore, elucidating the neural correlates of inhibitory control processes is crucial for developing novel treatment strategies to ameliorate the symptomatology of these disorders and to improve the quality of life. The development of preclinical translational paradigms to study inhibitory control processes has greatly enhanced our neurobiological understanding of these cognitive processes. Over the last decades, emphasis has been mainly on monoamines including dopamine and serotonin and their contribution to behavioral inhibition. This short review will focus on the involvement of the serotonergic system, and in particular serotonin1A receptors, in inhibitory control processes.

In the present experiment we analyzed whether the antianxiety action of the serotonergic 1A agonists buspirone (5 mg/kg), ipsapirone (5 mg/kg), indorenate (5 mg/kg), and 8-OH-DPAT (0.5 mg/kg) were mediated through the stimulation of pre- or postsynaptic serotonergic receptors. The experimental anxiety values were determined with the burying behavior test, where a reduction in the cumulative time of burying behavior was interpreted as a reduction in anxiety. To that purpose we analyzed the putative anxiolytic action of these drugs in animals with lesion of the serotonergic fibers after the intracerebroventricular (ICV) injection of 5,7-dihydroxytyptamine (5,7-DHT, 10 or 150 micrograms/10 microliters). The neurochemical analysis shows that these treatments produce a statistically significant reduction in 5-HT and 5-HIAA levels in various brain areas. The results of the behavioral experiments reveal that buspirone, ipsapirone, and indorenate produced exactly the same reduction in burying behavior in lesioned animals as compared with control rats. The reduction in burying behavior produced by 8-OH-DPAT was effectively prevented by the lesion with 5,7-DHT. These data suggest that the anxiolytic effect of buspirone, ipsapirone, and indorenate is mediated via the stimulation of postsynaptic receptors, while the somatodendritic receptors are involved in the antianxiety effect of 8-OH-DPAT.

These results show that [18F]MPPF can be used for measurement of drug-related 5-HT1A receptor occupancy and may be of particular interest in determining the 5-HT1A receptor interaction of new or established drugs in phase 1 and early phase 2 drug trials. Apparently, the 5-HT1A partial agonist buspirone is already clinically effective at low levels of 5-HT1A receptor occupancy.

The aim of this study was to assess the anxiolytic effect of berberine (abbrev. BER) using two experimental anxiety models in the mouse. In the black and white test of anxiety, berberine (100, 500 mg/kg) produced an increase in the first time entry, time spent in the white section, and total changes between two compartments. On the other hand, in the elevated plus-maze test, berberine (100, 500 mg/kg) produced an increase in the time spent and arm entries in the open arms, and a decrease in the time spent and arm entries in the closed arms. Berberine (500 mg/kg) decreased locomotor activity in mice. Furthermore, BER at 100, 500 mg/kg decreased concentrations of NE, DA and 5-HT, and increased the concentrations of VMA, HVA and 5-HIAA in the brain stem. BER also attenuated the anxiogenic effect of WAY-100635, 8-OH DPAT and DOI and enhanced the anxiolytic effect of BUS, p-MPPI and RIT in the elevated plus-maze. These results suggested that berberine at 100 mg/kg had a significant anxiolytic-like effect, which was similar to that observed with 1 mg/kg diazepam and 2 mg/kg buspirone. The anxiolytic mechanism of BER might be related to the increase in turnover rates of monoamines in the brain stem and decreased serotonergic system activity. Moreover, BER decreased serotonergic system activity via activation of somatodendritic 5-HT1A autoreceptors and inhibition of postsynaptic 5-HT1A and 5-HT2 receptors.

The enforced interval of copulation (EIC) consists of the artificial prolongation of the interintromission interval, induces a reduction in the number of intromissions preceding ejaculation, and is accompanied by an anxiety like behavioral repertoire. The administration of the benzodiazepine anxiolytics diazepam, chlordiazepoxide, flurazepam, and flunitrazepam produced a dose-dependent inhibition of the EIC effect with a concomitant increase in mounting. These actions were blocked by the central benzodiazepine antagonist Ro 15-1788. The anxiogenic agent beta-carboline Zk 39106 had no effect. Treatment with pentobarbital also produced a blockade of the reduction in the number of intromissions during EIC, whereas muscimol and bicuculline lacked this effect. The serotonergic anxiolytic buspirone reversed the facilitatory action induced by EIC; however, two putative serotonergic antianxiety agents, 8-OH-DPAT and ipsapirone, did not modify or potentiate it, respectively. Finally, the nonanxiolytic serotonergic compounds 5-hydroxytryptophan and TFMPP drastically increased the number of mounts but did not antagonize the reduction of intromissions produced by EIC. These results suggest that an increase in the anxiety levels may be responsible for the excitatory action of EIC on sexual behavior.

Generalized Anxiety Disorder (GAD) is a highly prevalent condition whose course of illness is often chronic in nature and fluctuating in severity. Pharmacotherapy options include the benzodiazepines, the azapirones, of which only buspirone is marketed at the present time, and the antidepressant imipramine. Buspirone is probably the treatment of choice when prolonged therapy is indicated because it does not produce physical dependence, dose not interact with alcohol, and does not cause psychomotor impairment. Dosing instructions for buspirone and guidelines for switching patients from benzodiazepines to buspirone are offered. Non-drug therapies such as interpersonal and cognitive therapies are often also found helpful in treating patients with GAD.

The accumulation of 3-methoxytyramine (3-MT), the O-methylated metabolite of dopamine (DA), in rat striatum was used to assess the effects of drugs on dopaminergic activity. This was accomplished by pretreating rats with pargyline to completely inhibit 3-MT catabolism. Under the conditions used, 3-MT accumulation was linear over time for at least 90 minutes. Apomorphine and gamma-butyrolactone, drugs which depress the activity of DA-containing neurons, decreased striatal 3-MT accumulation; whereas typical neuroleptics (haloperidol, fluphenazine, chlorpromazine), which increase the activity of DA-containing neurons, increased striatal 3-MT accumulation. In addition, a number of other drugs which block DA receptors and exert various atypical actions on dopaminergic functioning were examined. These "atypical" compounds (clozapine, buspirone, molindone) also increased striatal 3-MT accumulation, but were generally less potent than the typical neuroleptics examined. Moreover, the potencies of the typical neuroleptics and "atypical" compounds that were tested appear to be somewhat related to their affinities for D-2 DA receptors, as measured by their abilities to displace 3H-spiperone from rat striatal membrane preparations. Interestingly, this relationship was less evident when NaCl was omitted from the 3H-spiperone binding assay buffer. The potential antipsychotic drugs, BW 234U and SCH 23390, were also investigated for their effects on 3-MT accumulation and 3H-spiperone binding, and they were relatively inactive in both of these measures of dopaminergic activity.(ABSTRACT TRUNCATED AT 250 WORDS)

In this review the authors propose to study the impact of antidepressants on attention, memory and motor functions in healthy volunteers and depressed patients on single and long-term administration. After reviewing the principal cognitive functions, we examine the actual investigation means to conclude that the Critical Flicker Fusion Test (CFFT) is one of the most drug-sensitive tests. It permits a categorization in: sedative antidepressants that in single administration lower CFFT; compounds with no effect on CFFT and no deleterious cognitive effect; and finally substances that raise CFFT and may have psychostimulating properties. On single administration amitriptyline is the most sedative antidepressant on attention or motor level. It seems to produce negative effects on memory level. However, experimental trials give contradictory results. Imipramine in single administration also has sedative effects on memory and car driving capacity. However divergent results of experimental trials do not allow any conclusions of a clearcut negative cognitive effect. Memory impairments with imipramine appear at administration levels of 150 mg. Mianserin has a sedative impact on attention and motor level at low doses (10 mg). Among the tricyclics, nortriptyline has a highly dose dependent sedative effect that has been shown on attention tests (Time Reaction:TR, Digit Symbol Substitution Test: DSST). Among non-tricyclic compounds, doxepine lowers attention and motor performances. Maprotiline (75 mg) lowers CFFT and has a dose dependent effect. Trazodone also has a negative impact on attention tests. Finally viloxazine lowers CFFT but does not impair other attention or motor tests on a 100 mg doses. Buspirone, lofepramine, midalcipran and zimelidine are antidepressants with no effect on CFFT and do not have any positive or negative cognitive effect. On the other hand nomifensine, paroxetine and fluoxetine raise CFFT in healthy volunteers on single administration. Improvement of CFFT performances was found in an isolated manner for nomifensine and paroxetine on 30 mg doses with no other memory or motor effects. MAO-Inhibitors do not impair attention or motor function; thus moclobemide has no negative impact on memory, attention or car driving tests. Cognitive impact of antidepressants in depressive patients seems the same with those of healthy volunteers on single administration. In long-term administration antidepressants have different effects in healthy and depressed subjects. In healthy volunteers cognitive effects of most compounds are normalized after the second week of treatment. However, attention and motor performances with amitriptyline are normalized after 3 weeks of treatment. Sedative motor or cognitive effects of imipramine do not exceed 8 days.(ABSTRACT TRUNCATED AT 400 WORDS)

SSR181507, a dopamine D₂ receptor antagonist/partial agonist and 5-HT(₁A) receptor agonist, is active in animal models of schizophrenia. Furthermore, it shows activity in several anxiety and/or depression models (Depoortere et al. 2003). Presently, we sought to further characterize the latter two activities in rats, using a step-down passive avoidance procedure, a shock-induced ultrasonic vocalization (UV) test in adult subjects and a social interaction test. SSR181507 (0.3 & 1 mg/kg ip), but not the atypical antipsychotics clozapine and olanzapine, decreased the latency time to step-down from a "safety" platform. Effects of SSR181507 were reversed by the selective 5-HT(₁A) receptor antagonist SL88.0338. SSR181507 also reduced UV (0.3 & 1 mg/kg ip), an effect not reversed by SL88.0338, and observed with olanzapine, haloperidol, fluoxetine and the 5-HT(₁A) receptor agonists 8-OH-DPAT and buspirone, but not diazepam. Furthermore, SSR181507 remained active following 3 weeks of administration (1 mg/kg ip, once daily) in the UV test. Lastly, SSR181507 (3 mg/kg ip) potentiated social interaction, an effect shared by diazepam and buspirone, but not by olanzapine, clozapine, haloperidol and 8-OH-DPAT. These data further strengthen previous findings that the putative atypical antipsychotic SSR181507 has mixed antidepressant and anxiolytic activities.

Due to several mechanism, meals may modify the pharmacokinetics of drug products, thereby eliciting to clinically significant food interaction. Food interactions with the drug substance and with the drug formulation should be distinguished. Food interaction of different drug products containing the same active ingredient can be various depending on the pharmaceutical formulation technology. Particularly, in the case of modified release products, the food/formulation interaction can play an important role in the development of food interaction. Well known example, that bioavailability of theophylline can be influenced in different way (either increased, decreased or unchanged) by concomitant intake of food in the case of different sustained release products. The role and methods of food interaction studies in the different kinds of drug development (new chemical entity, modified release products, generics) are reviewed. Prediction of food effect response on the basis of the physicochemical and pharmacokinetic characteristics of the drug molecule or formulations is discussed. The results of three food interaction studies carried out the products of EGIS Pharmaceuticals Ltd. are also reviewed. The pharmacokinetic parameters of theophyllin 400 mg retard tablet were practically the same in both fasting condition and administration after consumption of a high fat containing standard breakfast. The ingestion of a high fat containing breakfast, increased the AUC of nifedipine from 259.0 +/- 101.2 ng h/ml to 326.7 +/- 122.5 ng h/ml and Cmax from 34.5 +/- 15.9 ng/ml to 74.3 +/- 23.9 ng/ml in case of nifedipine 20 mg retard tablet, in agreement with the data of literature. The statistical evaluation indicated significant differences between the pharmacokinetic parameters in the case of two administrations (before and after meal). The effect of a high fat containing breakfast for a generic version of buspiron 10 mg tablet and the bioequivalence after food consumption were studied in a single-dose, three-way (test and reference products administered after consumption of standard breakfast, as well as test product in fasting condition), cross-over, food effect bioequivalence study. According to the results, the test product--which, in a former study proved to be bioequivalent with the reference product in fasting state--is bioequivalent with the reference product under feeding conditions and the food intake influenced the pharmacokinetics of the test tablets.

Cocaine abuse may lead to overdose (related to seizures and/or status epilepticus) and to diseases (schizophrenia, depression, and anxiety). This work was designed to study the influence of drugs used to treat psychopathologies associated with cocaine abuse on cocaine-induced seizures and mortality in mice. Fluoxetine (10, 20, 40 mg/kg), imipramine and buspirone (5, 10 mg/kg), pimozide (10, 20 mg/kg), lithium (56.3, 112.5 mg/kg), and naltrexone (25, 50 mg/kg) were administered intraperitoneally, 30 minutes prior to cocaine (90 mg/kg, ip). The animals were observed (30 minutes) to determine: latency to first seizure, number of seizures, and number of deaths after cocaine overdose. Fluoxetine, imipramine, buspirone, and pimozide had pro- or anticonvulsant effects depending on the dose. Smaller doses protected and higher doses increased cocaine-induced seizures and/or mortality. Naltrexone worsened and lithium protected against seizures. Thus, these results suggest that caution should be taken in the selection of pharmacotherapy and dosages for patients with cocaine addiction because of the possibility of potentiating cocaine toxicity.

The effect of diazepam (1.0 mg/kg, i.p.) and buspirone (5.0 mg/kg, i.p.) on the burying behaviour latency (denoting actions on the animals' reactivity) and on the cumulative burying behaviour (directly reflecting the experimental anxiety levels), were analyzed in male-, intact females, at proestrus and metoestrus, and in neonatally-androgenized-rats. Androgenization was performed by injecting 60 micrograms/rat of testosterone propionate on day 5 after delivery. Two main groups of neonatally-androgenized rats were established: A group of animals showing permanent oestrus from the vaginal opening (acyclic females) and a group presenting the delayed anovulatory syndrome. Diazepam produced a clear reduction in experimental anxiety in males and neonatally-androgenized-females. Particularly important was the anxiolytic effect of diazepam on acyclic females that was accompanied by a significant increase in burying behaviour latency. Conversely, buspirone induced a clear reduction in burying behaviour, without modifying its latency, in all groups regardless of the gender and the neonatal treatment. Data are buy buspar discussed on the basis of the androgen participation on the anxiolytic drug effects. A possible age-related benzodiazepine actions in females is suggested.

Despite the large number of depressed patients who buy buspar do not respond to first-line antidepressants, the evidence base of alternate strategies is quite thin. In this article, a simple 5-stage system for categorizing treatment-resistant depression (TRD) is described and the evidence pertaining to the major strategies currently utilized is summarized using four grades, ranging from D (case reports only) to A (multiple positive placebo-controlled trials). It is concluded that the level of evidence supporting many of the contemporary strategies used for TRD (eg, combinations of antidepressants and augmentation with medications such as pindolol, buspirone, or modafinil) is scanty at best. Even the fundamental question concerning "to augment or to switch" is not answerable with available data. It is noted that the best-documented treatments (ie, lithium augmentation, switching to a monoamine oxidase inhibitor, and electroconvulsive therapy) are among the least utilized. This state of affairs will improve with completion of the studies of Systematic Treatment Alternatives to Relieve Depression, a large multicenter study of difficult-to-treat depression funded by the National Institute of Mental Health. There is a need for greater collaboration among academicians and organizations, such as the American Psychiatric Association, the National Institute of Mental Health, and the pharmaceutical industry, to ensure that sufficient research is conducted so that clinician's choices for patients with TRD can be guided by empirical evidence.

Poisoning by organophosphate nerve agents can induce seizures which rapidly become refractory to treatment and result in brain damage. Current therapies have only a narrow time frame for effective administration after poisoning. 5-HT1A agonists were tested for efficacy in mice against a seizure-producing combination of the carboxylesterase inhibitor 2-(o-cresyl)-4H-1:3:2-benzodioxaphosphorin-2-oxide (CBDP) and sarin, producing an LD20-40. Administration of the 5-HT1A agonist, 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) decreased glial fibrillary acidic protein (GFAP) staining in mice when administered 1min after CBDP and sarin while other buy buspar 5-HT1A agonists buspirone and S-14506 were not effective. The reduction in GFAP staining by 8-OH-DPAT remained significant when a single dose was administered 2h after the toxic challenge. In addition, 8-OH-DPAT reversed the increase in the inflammatory factor IL-1β in the dentate gyrus and amygdala but did not reduce positive TUNEL staining in the dentate gyrus. Due to the failure of the two other agonists to provide protection, the 5-HT1A antagonist WAY-100635 was tested. WAY-100635 was found to neither reverse the neuroprotective effects of 8-OH-DPAT nor worsen the damage when given alone, making a role for this receptor unlikely. The neuroprotective effects of 8-OH-DPAT appear to lie within its secondary pharmacology.

To expand the generalizability of the chick separation stress paradigm as a high-throughput anxiolytic screen, six positive drug probes (doses in mg/kg: meprobamate 15-120, pentobarbital 2.5-20.0, chlordiazepoxide 2.5-15.0, buspirone 2.5-10.0, imipramine 1-15, and clonidine 0.10-0.25) and five negative drug probes (amphetamine 0.5-4.0, scopolamine 0.2-1.6, caffeine 5-20, chlorpromazine 1-30, and haloperidol 0.03-1.00) were evaluated in the test. Seven-day-old chicks received intramuscular injections of either vehicle or drug probe 15 min prior to tests in either a mirror (low-stress) or a no-mirror (high-stress) condition for a 3-min observation period. The dependent measures were distress vocalizations to index separation stress and sleep onset latency to index sedation. All positive drug probes attenuated distress vocalizations in a dose-dependent manner, except buspirone. All positive drug probes affected sleep onset latency in a dose-dependent manner, except buspirone and imipramine. In all cases, the anxiolytic-like effect of positive drug probes was greater than its sedative effect. None of the negative drug probes affected either distress vocalizations or sleep onset latency, except for the highest dose of amphetamine, which caused pronounced stereotypy. These findings demonstrate that buy buspar this anxiolytic screen is sensitive to a wide range of positive pharmacological probes and insensitive to a wide range of negative pharmacological probes.

Three anxiolytic drugs (bromazepam 3 mg, buspirone 10 mg, and clobazam 10 mg p.o.) were evaluated for their effects on memory, psychomotor performance and subjective response in a double-blind, placebo-controlled, crossover study in 20 healthy volunteers. At each session, measurements were made before and 2 and 6 h after drug administration. The psychometric tests used were the images test, digit/symbol substitution test (DSST), choice reaction time (CRT), and critical fusion frequency (CFF). Free recall after 30 s in the 2-hour session was altered for all 3 drugs as compared to placebo (p less than 0.01), but in the 6-hour session only bromazepam showed a significant difference (p less than 0.05). The number of symbols reproduced by subjects during DSST was significantly decreased by bromazepam and buspirone as compared to placebo (p less than 0.05), whereas clobazam showed no differences with placebo. Analysis of variance for all four treatments (the 3 drugs and the placebo) showed no differences at recognition time or for motor response in CRT, except between bromazepam and clobazam after 6 h (p less than 0.05). None of the drugs altered performance during CFF (except bromazepam), and clobazam actually improved performance. All the drugs studied buy buspar disturbed acquisition phenomena or restitution of memory; however, only bromazepam and buspirone significantly modified performance during DSST and disturbed the recognition and processing of sensory data.

Chronic buspirone or ipsapirone (3 mg/kg, twice daily) administration to rats for 10 days decreased the sensitivity of inhibition of single-unit activity of serotonergic dorsal raphe neurons to a challenge by each drug. The ED50 for buspirone was increased from 0.1 mg/kg to 1.8 mg/kg, and the ED50 for ipsapirone was increased from 0.7 mg/kg to 1.2 mg/kg. The binding properties (Kd and Bmax) of [3H]8-OH-DPAT to membranes of cerebral cortex and hippocampus were unaffected by chronic administration of either buspirone or ipsapirone. Chronic buspirone or ipsapirone administration increased the tolerance of the hypothalamic-pituitary-adrenal axis (HPAA) following a challenge by each drug. The ED50 for elevation of plasma corticosterone levels was increased from 4.0 mg/kg to buy buspar 7.6 mg/kg for buspirone and 6.2 mg/kg to 8.0 mg/kg for ipsapirone.

The other patients had ingested moclobemide together with Diamox Mg citalopram (2 cases) and clomipramine (1 case). Moreover, other serotoninergic pharmaceuticals as sertraline and sumatriptan were simultaneously ingested in one case and buspirone in another. Three of the cases had hyperthermia, > 40 degrees C and the same number showed pronounced muscle rigidity, coma and mydriasis. Other severe signs and symptoms upon admission included positive Babinski and trismus in two cases each and seizures in one. All patients received mechanical ventilation.

The present study was undertaken to compare the properties of the [3H]8-OH-DPAT (8-hydroxy-2-(di-n-propylamino)tetralin) binding site in the dorsal raphe nucleus with the hippocampal 5-HT1A receptor. In both tissues inclusion of 1 mM Mg2+ enhanced specific [3H]8-OH-DPAT binding, while 1 mM GTP decreased radioligand binding. [3H]8-OH-DPAT appears to bind to a single population of binding sites in both the hippocampus and the dorsal raphe nucleus, although the K(d) for the radioligand at the dorsal raphe site was five times that observed at the hippocampal 5-HT1A receptor. Similarly, although 5-HT and selective 5-HT1A receptor ligands displayed high affinity for the [3H]8-OH-DPAT binding site in the dorsal raphe nucleus, Vasotec Dosage the affinity at the dorsal raphe site was less than that observed at the hippocampal 5-HT1A receptor. 8-OH-DPAT inhibited forskolin-stimulated adenylyl cyclase activity in the hippocampus, but did not alter enzyme activity in the dorsal raphe nucleus. Conversely, 8-OH-DPAT inhibited the accumulation of [3H]inositol phosphates in the dorsal raphe nucleus, but not in the hippocampus. An inhibition of phosphoinositide hydrolysis in the dorsal raphe nucleus also was found with the putative 5-HT1A receptor selective ligands, flesinoxan and gepirone. However, addition of another putative 5HT1A receptor selective ligand, buspirone, did not alter the generation of [3H]inositol phosphates, but blocked the inhibitory effect of 8-OH-DPAT on phosphoinositide hydrolysis. These studies demonstrate that the 8-OH-DPAT binding site in the dorsal raphe nucleus displays a binding profile which is similar to the hippocampal 5-HT1A receptor, but unlike this 5-HT1A receptor the binding site in the dorsal raphe nucleus is negatively coupled to phosphoinositide turnover.

In many animal studies, acute treatment with the novel anxiolytic agent buspirone exhibits only minimal "anxiolytic efficacy" (i.e., increases in punished responding) when compared to benzodiazepines and barbiturates. The present studies examined the effects of acute pre-test challenges with buspirone in subjects receiving chronic post-test buspirone or saline treatments. Chronic post-test treatment with buspirone (4 mg/kg/day for 4 weeks, followed by 8 mg/kg/day for 12 weeks) did not significantly affect CSD behavior. Consistent with previous reports, acute pre-test administration of buspirone (0.125-2 mg/kg, IP) to subjects receiving chronic post-test saline treatment resulted in only a modest anti-conflict effect in the CSD paradigm (approximately ten shocks over control). In Ponstel Medication contrast, subjects chronically treated with buspirone exhibited a dramatically greater anti-conflict effect following acute challenge with buspirone (up to 40 shocks over control). These data are consistent with the hypothesis that the full anxiolytic efficacy of buspirone requires repeated administration.

Obsessive-compulsive disorder (OCD) is a common heterogeneous psychiatric disorder manifesting with obsessions and compulsions. Obsessions are intrusive, recurrent, and persistent unwanted thoughts. Compulsions are repetitive behaviors or mental acts that an individual feels driven to perform in response to the obsessions. The heterogeneity of OCD includes themes of obsessions, types of rituals, presence or absence of tics, etiology, genetics, and response to pharmacotherapy. Complications of OCD include interpersonal difficulties, unemployment, substance abuse, criminal justice issues, and physical injuries. Areas of the brain involved in the pathophysiology include the orbitofrontal cortex, anterior cingulate gyrus, and basal ganglia. Overall, OCD may be due to a malfunction in the cortico-striato-thalamo-cortical circuit in the brain. Neurotransmitters implicated in OCD include serotonin, dopamine, and glutamate. Numerous drugs such as atypical antipsychotics and dopaminergic agents can cause or exacerbate OCD symptoms. The etiology includes genetics and neurological insults. Treatment of OCD includes psychotherapy, pharmacotherapy, electroconvulsive therapy, transcranial magnetic simulation, and in extreme cases surgery. Exposure and response prevention is the most effective form of psychotherapy. Selective serotonin reuptake inhibitors (SSRIs) are the preferred pharmacotherapy. Higher doses than listed in the package insert and a longer trial are often needed for SSRIs than compared to other psychiatric disorders. Alternatives Ponstel S Syrup to SSRIs include clomipramine and serotonin/norepinephrine reuptake inhibitors. Treatment of resistant cases includes augmentation with atypical antipsychotics, pindolol, buspirone, and glutamate-blocking agents.

The neurochemical profile of the selective 5-HT1A receptor antagonist WAY100135 [N-tert-butyl 3-4-(2-methoxyphenyl) piperazin-1-yl-2-phenylpropanamide dihydrochloride] and its enantiomers at the somatodendritic 5-HT1A receptor was determined by studying the effects of these compounds on 5-HT (5-hydroxytryptamine, serotonin) release in the rat hippocampus using in vivo microdialysis. (+/-)-WAY100135, (+)-WAY100135 and (-)-WAY100135 (all at 10 mg/kg s.c.) had no significant effect on extracellular levels of 5-HT in the hippocampus demonstrating that these compounds are devoid of 5-HT1A receptor agonist properties. In contrast, the 5-HT1A receptor agonist 8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) (0.1 mg/kg s.c.) and the partial agonists BMY 7378 (1.0 mg/kg s.c.) and buspirone (5 mg/kg s.c.) significantly decreased hippocampal 5-HT. Pretreatment with (+/-)-WAY100135 (at 10 mg/kg s.c.) and (+)-WAY100135 (at 1.0-10 mg/kg s.c.) completely blocked the 8-OH-DPAT-induced decrease in 5-HT release demonstrating that these compounds are antagonists at the somatodendritic 5-HT1A autoreceptor. (-)-WAY100135 at a dose of 10 mg/kg s.c. had no significant effect on the 8-OH-DPAT-induced inhibition of 5-HT release. (+/-)-WAY100135 had no significant effect on extracellular levels of dopamine in the rat hippocampus but significantly increased extracellular levels of noradrenaline. The mechanism underlying the increase in noradrenaline is unknown at present.(ABSTRACT TRUNCATED AT 250 WORDS)

In experiments on rats in elevated plus-maze and in Opto Varimex apparatus, used for studying exploratory behavior, we observed that dotarizine (DOT), a drug with Ca2+ and 5-HT1/5-HT2-receptor antagonistic action, exerted effects suggesting anxiolytic action. The 5-HT uptake inhibitor fluoxetine (FLU) produced mainly anxiogenic effects. The simultaneous administration of DOT and FLU weakened the anxiolytic effect of DOT. The effects of the 5-HT1B/5-HT1C receptor agonist with promigraine action, m-chlorophenylpiperazine (m-CPP), indicated anxiogenic action, which was increased to a certain extent when it was combined with FLU. Some of the other 5-HT-receptor agonists and antagonists tested showed anxiogenic action and others anxiolytic action. In most cases, these effects were changed when they were administered simultaneously with FLU. DOT increased general locomotor activity and when combined with FLU this effect tended to decrease. In contrast, m-CPP decreased general locomotor activity and this effect was potentiated by FLU. DOT at the two doses used did not significantly change the rate of development of habituation, while m-CPP, buspirone and ondansetron increased it. The behavioral effects of DOT observed in all cases opposite to the same effects of the promigraine drug m-CPP suggest an antimigraine action of DOT.

Pharmacodynamic changes were significantly intercorrelated; all effects were maximal 1 to 2 hours after dosage but were indistinguishable from placebo by 8 hours. Buspirone did not alter the EEG or DSST performance but did increase self-ratings of sedation and feeling "spacey" and impaired memory function; these effects generally were quantitatively less than with triazolam. Peak plasma triazolam concentrations preceded maximum pharmacodynamic effects; the mean plasma effect site equilibration half-life was 9.4 minutes. Kinetic-dynamic modeling procedures yielded significant relationships between hypothetical effect site triazolam concentrations and pharmacodynamic changes.
