hydrochloride. The
inactive ingredients present are ascorbyl palmitate, colloidal silicon

H

S•HCl and its molecular weight is 320.88.
Promethazine hydrochloride, a phenothiazine derivative, is designated
chemically as (±)-
10-[2-(Dimethylamino)propyl] phenothiazine monohydrochloride with the
following
structural formula:
Promethazine hydrochloride USP occurs as a white to faint yellowish,
crystalline
powder. It is very soluble in water, freely soluble in ethanol and in
methanol, practically
insoluble in ethyl acetate, diethyl ether and acetone.
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.
