PROMETHAZINE HYDROCHLORIDE- PROMETHAZINE HYDROCHLORIDE SUPPOSITORY A-S MEDICATION SOLUTIONS ---------- PROMETHAZINE HYDROCHLORIDE SUPPOSITORIES, USP RX ONLY DESCRIPTION Each rectal suppository contains 12.5 mg or 25 mg promethazine HCl with ascorbyl palmitate, colloidal silicon dioxide, glyceryl monostearate, hard fat, and white wax. Promethazine HCl Suppositories, USP are for rectal administration only. Promethazine HCl is a racemic compound; the empirical formula is C H N S∙HCl and its molecular weight is 320.88. Promethazine HCl, a phenothiazine derivative, is designated chemically as 10_H_- Phenothiazine, 10-ethanamine, _N,N,_ α-trimethyl-, monohydrochloride, (±)- with the following structural formula: Promethazine HCl 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. 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 metabolized by the liver to a variety of compounds; the sulfoxides of promethazine and N-demethylpromethazine are the predominant metabolites appearing in the urine. 17 20 2 1 INDICATIONS AND USAGE Promethazine HCl Suppositories, USP are useful for: Perennial and seasonal allergic rhinitis.
