Buspirone hydrochloride tablets, USP are an antianxiety agent that is not chemically or pharmacologically related to the benzodiazepines.
In a study in normal volunteers, concomitant administration of buspirone and haloperidol resulted in increased serum haloperidol concentrations. The clinical significance of this finding is not clear.

Buspirone, brand name Buspar, is an anxiolytic drug that is primarily used to treat generalized anxiety disorder (GAD). It is also commonly used to augment.
It preferentially blocks inhibitory presynaptic D 2 autoreceptors, and antagonizes postsynaptic D 2 receptors only at higher doses. Buspirone has also been found to bind with high affinity to the D 3 and D 4 receptors (K i = 98 nM and 29 nM, respectively). In addition to the 5-HT 1A receptor, buspirone is a weak antagonist of the dopamine D 2 receptor (K i = 240 nM), with approximay 15-fold lower affinity for this receptor relative to the 5-HT 1A receptor. In accordance, buspirone has been found to increase dopaminergic neurotransmission in the nigrostriatal pathway at low doses, whereas at higher doses, postsynaptic D 2 receptors are blocked and antidopaminergic effects such as hypoactivity and reduced stereotypy, though notably not catalepsy, are observed in animals.
Structural analogues of buspirone include tandospirone, gepirone, and perospirone.
It is not uncommon for a very low-dose benzodiazepine to be prescribed in addition to buspirone, for treating acute episodes if/when they occur (buspirone's constant anxiolytic effect greatly reduces the minimum effective dose of benzodiazepines and barbiturates and therefore makes them significantly more-tolerable for use at work/driving/performing other activities which require the patient's full cognitive capacity).
