PROMETHAZINE HYDROCHLORIDE
DESCRIPTION
Promethazine Hydrochloride, a phenothiazine derivative, is designated
chemically as 10-
[2-(Dimethylamino)propyl]phenothiazine monohydochloride and has the
following
structural formula:
Promethazine hydrochloride is a racemic compound; the empirical
formula is
C17H20N2S HCl and its molecular weight is 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 freely soluble in water and soluble in alcohol.
Each tablet for oral administration contains 12.5 mg, 25 mg or 50 mg
promethazine
hydrochloride, USP. The inactive ingredients include: lactose
anhydrous, magnesium
stearate, and microcrystalline cellulose. The 50 MG also contains D&C
Red # 27 Lake.
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 H1 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 for 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.
Vasomotor rhinitis.
