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.
