BUSPIRONE HYDROCHLORIDE
Buspirone hydrochloride is indicated for the management of anxiety disorders or the short-term relief of anxiety symptoms. Its efficacy has been specifically demonstrated in Generalized Anxiety Disorder (GAD), characterized by persistent symptoms such as motor tension, autonomic hyperactivity, apprehensive expectation, and vigilance/scanning. Clinical evidence supports its use in patients presenting with anxiety and coexisting depressive symptoms. It is generally not intended for the treatment of anxiety or tension associated with the stress of everyday life.
How BUSPIRONE HYDROCHLORIDE Works
The exact mechanism of action of buspirone is not fully elucidated. Unlike benzodiazepines, buspirone does not interact directly with GABA receptors. It functions primarily as a high-affinity partial agonist at serotonin 5-HT1A receptors. It also exhibits moderate affinity for dopamine D2 receptors, where it acts as an antagonist or partial agonist. It does not possess significant anticonvulsant or muscle relaxant properties and lacks the sedative-hypnotic effects typical of other anxiolytics.

ProIndications & Usage
Buspirone hydrochloride tablets are indicated for the management of anxiety disorders or the short-term relief of the symptoms of anxiety. Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic. The efficacy of buspirone hydrochloride tablets has been demonstrated in controlled clinical trials of outpatients whose diagnosis roughly corresponds to Generalized Anxiety Disorder (GAD). Many of the patients enrolled in these studies also had coexisting depressive symptoms and buspirone hydrochloride tablets relieved anxiety in the presen...
