CLINICAL PHARMACOLOGY:
Diphenhydramine hydrochloride is an antihistamine with anticholinergic
(drying) and sedative effects.
Antihistamines appear to compete with histamine for cell receptor
sites on effector cells.
A single oral dose of diphenhydramine hydrochloride is quickly
absorbed with maximum activity
occurring in approximately one hour. The duration of activity
following an average dose of
diphenhydramine hydrochloride is from four to six hours.
Diphenhydramine is widely distributed
throughout the body, including the CNS. Little, if any, is excreted
unchanged in the urine; most appears
as the degradation products of metabolic transformation in the liver,
which are almost completely
excreted within 24 hours.
