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.
INDICATIONS AND USAGE
Promethazine hydrochloride tablets are useful for:
Perennial and seasonal allergic rhinitis.
Vasomot
