ACTION
NOVO-DOXEPIN (doxepin HCl) is a psychotropic agent with antidepressant
and
anxiolytic properties. It also has sedative and anticholinergic
effects, and, in the higher
dosage range, it produces peripheral adrenergic blocking effects.
Studies of
electroencephalograms in humans have shown decreases in amplitude, and
amplitude
variability, also, the delta, theta and 24-35 CPS activities
increased.
A comparative, two-way, single-dose bioavailability study was
performed on NOVO-
DOXEPIN and SINEQUAN
®
150mg Capsules. The pharmacokinetic data calculated for
the NOVO-DOXEPIN and SINEQUAN
®
Capsule formulations are tabulated below:
