🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Desvenlafaxine is a potent and selective serotonin and norepinephrine reuptake inhibitor (SNRI). It works by blocking the reuptake of serotonin and norepinephrine at the synaptic cleft, thereby increasing their availability in the central nervous system. This enhanced neurotransmission is thought to contribute to its antidepressant effects. Unlike some other antidepressants, desvenlafaxine has minimal affinity for muscarinic, histaminergic, and adrenergic receptors, which may result in a lower incidence of certain side effects.
