描述 | Sulpiride is a substituted benzamide with selective dopaminergic blocking activity. Sulpiride was selective for dopamine (D)2 receptors and also blocks D3 and D4 receptors. Sulpiride does not block D1, adrenergic, cholinergic, gamma-aminobutyric acid-ergic, histaminergic, or serotonergic receptors to an appreciable extent. The oral bioavailability of sulpiride is poor, with estimates approximating 35%. Sulpiride may cause extrapyramidal effects, autonomic effects, tardive dyskinesia, and the neuroleptic malignant syndrome[3]. At low dosages (50 to 150 mg/day), sulpiride produces a disinhibiting and antidepressant effect, which is probably related to its action on D2 presynaptic autoreceptors, thus facilitating dopaminergic neurotransmission[4]. Sulpiride and melatonin reduce tinnitus perception, decreasing dopamine activity[5]. Sulpiride attenuated by 36% the anorexia produced by intrahypothalamic injections of amphetamine[6]. |
