THERAPEUTIC CLASSIFICATION
Anxiolytic
ACTIONS AND CLINICAL PHARMACOLOGY
Buspirone is a psychotropic drug with selective anxiolytic properties
which belongs chemically to
the class of compounds known as the azaspirodecanediones, not
chemically or pharmacologically
related to benzodiazepines, barbiturates, or other known psychotropic
agents.
Buspirone shares some of the properties of the benzodiazepines and the
neuroleptics, as well as
demonstrating other pharmacological action. Buspirone attenuates
punishment suppressed
behaviour in animals and exerts a taming effect, but is devoid of
anticonvulsant and muscle relaxant
properties and does not bind to the benzodiazepine/GABA receptor
complex. Buspirone affects a
variety of dopamine mediated biochemical and behavioural events, but
is free of cataleptic activity.
Buspirone has an affinity for brain D
2
-dopamine receptors, where it acts as an antagonist and
agonist, and for the 5-HT
1A
receptors, where it acts as an agonist. Buspirone does not block the
neuronal reuptake of monoamines and, on chronic administration; it
does not lead to changes in
receptor density in the models investigated. However, the mechanism of
action of buspirone in man
remains to be elucidated.
Buspirone is rapidly absorbed in man and undergoes extensive first
pass metabolism. Following oral
administration, low peak plasma levels of unchanged drug, of 1 to 6
ng/mL were observed 40
to 90 minutes after a single 20 mg dose. In a number of studies
performed in healthy volunteers, the
mean half-life of buspirone ranged from 2 to 3 hours up to
approximately 11 hours with
considerable variation in individual values. Multiple dose studies
suggest that
