Description and Uses

Promethazine is a first generation histamine H1 receptor antagonist (Ki = 2.6 nM) whose antihistamine activity has been reported in guinea pigs and mice at ED50 values of 0.43 and 5.9 mg/kg, respectively. Promethazine can penetrate the CNS, depressing central H1 receptor activity, which may relate to its sedative properties, and can also inhibit muscarinic acetylcholine receptors (Ki = 22 nM). Furthermore, 32 mg/kg promethazine demonstrates antiemetic effects in ferret models of motion sickness or chemotherapy-induced nausea.
