PROMETHAZINE HYDROCHLORIDE- PROMETHAZINE HYDROCHLORIDE TABLET ACTAVIS PHARMA, INC. ---------- PROMETHAZINE HYDROCHLORIDE TABLETS USP REVISED: DECEMBER 2016 RX ONLY DESCRIPTION Promethazine hydrochloride is a racemic compound. Promethazine hydrochloride, a phenothiazine derivative, is designated chemically as 10_H_- Phenothiazine-10-ethanamine, _N, N_,α-trimethyl-, monohydrochloride, (±)- with the following structural formula: C H N S•HCl M.W. 320.88 Promethazine hydrochloride occurs as a white to faint yellow, practically odorless, crystalline powder which slowly oxidizes and turns blue on prolonged exposure to air. It is soluble in water and freely soluble in alcohol. Each tablet, for oral administration, contains 25 mg or 50 mg of promethazine hydrochloride. In addition each tablet contains the following inactive ingredients: dibasic calcium phosphate, magnesium stearate, microcrystalline cellulose, sodium starch glycolate and stearic acid. Promethazine Hydrochloride Tablets USP, 50 mg also contain anhydrous lactose. CLINICAL PHARMACOLOGY Promethazine is a phenothiazine derivative which differs structurally from the antipsychotic phenothiazines by the presence of a branched side chain and no ring substitution. It is thought that this configuration is responsible for its relative lack (1/10 that of chlorpromazine) of dopamine antagonist properties. Promethazine is an H receptor blocking agent. In addition to its antihistaminic action, it provides clinically useful sedative and antiemetic effects. Promethazine is well absorbed from the gastrointestinal tract. Clinical effects are apparent within 20 minutes after oral administration and generally last four to six hours, although they may persist as long as 12 hours. Promethazine is metabolized by the liver to a variety of compounds; the sulfoxides of promethazine and N-demethylpromethazine are the predominant metabolites appearing in the urine.
