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.
