How it works
Buspirone is a member of the azapirone class of drugs. It has anxiolytic activity, but is largely lacking in sedative and muscle relaxant effects and anticonvulsant activity. Its mechanism of action has yet to be fully explained. Evidence to date suggests that its activity is based on its effects on serotonin (5-HT) receptors. It acts as an agonist of pre-synaptic and partial agonist of post-synaptic 5-HT1A subtype receptors. It is thought this initiates long-term changes in central 5-HT neurotransmission, producing the efficacy seen in the treatment of anxiety. Buspirone is thought to have antagonist activity at D2 receptors at the doses stipulated for anxious disorders, though it is unclear if this is linked to its anxiolytic activity. Buspirone's effects on GABAergic mechanisms are unclear. It does not directly interact with either the benzodiazepine-GABA receptor complex or GABA receptors. However, there is indirect evidence for buspirone having a GABA antagonist-like action.

Busron Tablets Precautions
Precaution

It will not block the withdrawal syndrome often seen with cessation of therapy with these agents. Patients should be gradually withdrawn from these agents before initiating buspirone treatment.
Busron Tablets Warnings
Warning 1
The administration of buspirone to a patient taking a monoamine oxidase inhibitor (MAOI) may pose a hazard. There have been reports of the occurrence of elevated blood pressure when buspirone has been added to a regimen including a MAOI. Therefore, it is recommended that buspirone not be used concomitantly with a MAOI.
Warning 2
Buspirone should not be used alone to treat depression, and may potentially mask the clinical signs of depression.
Warning 3
Concomitant administration of buspirone and other serotonergic agents, such as MAO inhibitors, selective serotonin re-uptake inhibitors (SSRIs), serotonin norepinephrine re-uptake inhibitors (SNRIs) or tricyclic antidepressants may result in serotonin syndrome, a potentially life-threatening condition .
