Drug

D1389 | Doxepin

Molecular Formula C19H21NO
Molecular Weight 279.4
Structure
State solid
Clearance The mean total apparent plasma clearance of a single oral dose of 50 mg doxepin in healthy individuals is 0.93 l/hr/kg.[A1945]
Volume of distribution The mean apparent volume of distribution of doxepin is reported to be of 20 L/kg.[T388]
Route of elimination The elimination profile of doxepin is presented as biphasic.[A1945] It is excreted in the urine mainly in the form of glucuronide conjugates. Less than 3% of a doxepin dose is excreted in the urine as parent compound or nordoxepin.[L1347]
Protein binding Equilibrium dialysis indicates a mean protein binding of 75.5% for doxepin and 76% for desmethyldoxepin.[A1945]
Half life The mean elimination half-life is reported to be of 15 hours.[T388]
Absorption Doxepin is moderately absorbed following oral ingestion with a bioavailability of 30%.[T388] The median peak concentration of doxepin ranges from 8.8-45.8 ng/ml and it is achieved 3.5 hours after initial administration. Its absorption is increased with concomitant administration of a high-fat meal.[L5995]
