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 C
H N S 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
