Lorcaserin is a full agonist for 5-HT 2C and 5-HT 2B receptors and partial agonist for 5-HT 2A receptors (75% of the maximal response elicited by serotonin). [7] Lorcaserin is a potent and selective 5-HT 2C agonist with rapid oral absorption that shows dose-dependent decrease in food intake and body weight.
Azapirones such as buspirone, gepirone, and tandospirone are 5-HT 1A receptor partial agonists marketed primarily as anxiolytics, but also as antidepressants. The antidepressants vilazodone and vortioxetine are 5-HT 1A receptor partial agonists. Flibanserin, a drug used for female sexual dysfunction, is a 5-HT 1A receptor partial agonist.
The 5-HT 1B receptor as an example of a metabotropic serotonin receptor. 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.
These effects are the result of activation of 5-HT 1A receptors within the rostral ventrolateral medulla. [10] The sympatholytic antihypertensive drug urapidil is an α 1-adrenergic receptor antagonist and 5-HT 1A receptor agonist, and it has been demonstrated that the latter property contributes to its overall therapeutic effects.
The 5-HT receptors, the receptors for serotonin, are located on the cell membrane of nerve cells and other cell types in animals, and mediate the effects of serotonin as the endogenous ligand and of a broad range of pharmaceutical and psychedelic drugs. Except for the 5-HT 3 receptor, a ligand-gated ion channel, all other 5-HT receptors are G ...
The 5-HT 2C receptor is a subtype of the 5-HT2 receptor that binds the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Like all 5-HT2 receptors, it is a G protein-coupled receptor (GPCR) that is coupled to G q /G 11 and mediates excitatory neurotransmission.
The 5-HT 2 receptors are a subfamily of 5-HT receptors that bind the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). [1] The 5-HT 2 subfamily consists of three G protein-coupled receptors (GPCRs) which are coupled to G q /G 11 and mediate excitatory neurotransmission, [2] including 5-HT 2A, 5-HT 2B, and 5-HT 2C.

To be precise, SMSs simultaneously modulate one or more serotonin receptors and inhibit the reuptake of serotonin. The term was created to describe the mechanism of action of the serotonergic antidepressant vortioxetine, which acts as a serotonin reuptake inhibitor (SRI), agonist of the 5-HT 1A receptor, and antagonist of the 5-HT 3 and 5-HT 7 ...
