This study was carried out to determine the metabolic pathways of buspirone and cytochrome P450 (P450) isoform(s) responsible for buspirone metabolism in human liver microsomes (HLMs). Buspirone mainly underwent N-dealkylation to 1-pyrimidinylpiperazine (1-PP), N-oxidation on the piperazine ring to buspirone N-oxide (Bu N-oxide), and hydroxylation to 3'-hydroxybuspirone (3'-OH-Bu), 5-hydroxybus...
We have evaluated the effect of buspirone (1.5 mg/kg/day, p.o.) type 1 diabetes induced cardiovascular complications induced by streptozotocin (STZ, 45 mg/kg, i.v.) in Wistar rats. Various biochemical, cardiovascular, and hemodynamic parameters were measured at the end of 8 weeks of treatment. STZ produced significant hyperglycaemia, hypoinsulinemia, and dyslipidemia, which was prevented by bus...
Buspirone, a partial agonist of 5-hydroxytryptamine autoreceptors, selectively blocks presynaptic nigrostriatal D2 dopamine (DA) autoreceptors. At doses which antagonised action of apomorphine in biochemical presynaptic nigrostriatal D2 DA autoreceptor test systems buspirone neither induced catalepsy nor antagonised apomorphine-induced turning behaviour in rats indicating that at these doses bu...
The objective of this investigation was to compare the in vivo potency and intrinsic activity of buspirone and its metabolite 1-(2-pyrimidinyl)-piperazine (1-PP) in rats by pharmacokinetic-pharmacodynamic modeling. Following intravenous administration of buspirone (5 or 15 mg/kg in 15 min) or 1-PP (10 mg/kg in 15 min), the time course of the concentrations in blood were determined in conjunctio...
OBJECTIVES To determine safety and efficacy of the 5HT1A serotonin partial agonist buspirone on core autism and associated features in children with autism spectrum disorder (ASD). STUDY DESIGN Children 2-6 years of age with ASD (N = 166) were randomized to receive placebo or 2.5 or 5.0 mg of buspirone twice daily. The primary objective was to evaluate the effects of 24 weeks of buspirone on ...
Buspirone hydrochloride is a now nonbenzodiazepine, non-barbiturate, non-narcotic t ranquil izer . It is an 'agaspirodecanedione", lipophilic and a heterocyclic compound. Absorption of buspironc from gastrointestinal tract is virtually complete. Peak plasma level is achieved in less, than one hour after a single dose. T h e elimination half life of the drug ranges from 2 to 8 hours in healthy s...
The actions of 5-hydroxytryptamine (5-HT) and buspirone, an anxiolytic agent that displays high and selective affinity for 5-HT1A receptor sites, on synaptic activation of hippocampal CA1 pyramidal cells were studied in vitro. Whereas 5-HT application leads to a rapid hyperpolarization and decreased input resistance in pyramidal cells, buspirone has no measurable effects on membrane potential a...
Sleep deprivation can lead to various alterations at physiological and psychological levels such as EEG changes, metabolic changes, irritation, blurred vision, memory lapses, hallucinations, psychosis and can even lead to death. Treatment still remains a challenge as hypnotics are associated with side effects. The objective of the present study was to investigate the protective effects of melat...
AbstractObjectives: To investigate the efficacy and side effects of buspirone in comparison with methylphenidate for controlling symptoms of children with attention deficit hyperactivity disorder (ADHD). Method: A total of thirty two 6-12 years old children with ADHD were examined. The teacher and parent ADHD Rating Scale (ADHD-RS) was used to gather data from both groups. Drug side effects wer...
The present study investigated the effect of buspirone on memory formation in an aversive learning task. Male Wistar rats were trained on the inhibitory avoidance task and tested for retention 1 day after training. They received peripheral or intra-amygdala administration of buspirone or other 5-HT1A drugs either before or after training. Results indicated that pretraining systemic injections o...
