Buspirone. Buspirone, sold under the brand name Buspar, among others, is an anxiolytic, a medication primarily used to treat anxiety disorders, particularly generalized anxiety disorder (GAD). [10][11] It is a serotonin 5-HT 1A receptor partial agonist, increasing action at serotonin receptors in the brain. [3]
5-HT 1A receptor (as partial or full agonists) 5-HT 2A receptor (as inverse agonists) D 2 receptor (as antagonists or partial agonists) α 1-adrenergic receptor (as antagonists) α 2-adrenergic receptor (as antagonists) Actions at D 4, 5-HT 2C, 5-HT 7, and sigma receptors have also been shown for some azapirones.

Buspirone/testosterone (tentative brand name Lybridos) is a combination of buspirone, a 5-HT 1A receptor partial agonist, α 2-adrenergic receptor antagonist, and D 2 autoreceptor antagonist, [1] and testosterone, an androgen or androgen receptor agonist, which is under development by the pharmaceutical company Emotional Brain for the treatment of female sexual dysfunction.
The neurotransmitter serotonin (illustration) has various receptors. A serotonin receptor agonist is an agonist of one or more serotonin receptors. They activate serotonin receptors in a manner similar to that of serotonin (5-hydroxytryptamine; 5-HT), a neurotransmitter and hormone and the endogenous ligand of the serotonin receptors.
The 5-HT3 antagonists, informally known as " setrons ", are a class of drugs that act as receptor antagonists at the 5-HT 3 receptor, a subtype of serotonin receptor found in terminals of the vagus nerve and in certain areas of the brain. With the notable exceptions of alosetron and cilansetron, which are used in the treatment of irritable ...

Its crystallographic structure in ribbon representation. 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems. [1][2][3] They mediate both excitatory and inhibitory neurotransmission.
The 5-HT 2A receptor is a subtype of the 5-HT 2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR). [4] The 5-HT 2A receptor is a cell surface receptor, [5] but has several intracellular locations. [6] Like all 5-HT 2 receptors, the 5-HT 2A receptor is G q /G 11-protein coupled.
