Doxepin is a tricyclic antidepressant primarily used in the treatment of major depressive disorder, anxiety disorders, and insomnia. It is approved for use in several countries and is known to have antihistaminic, anticholinergic, and sedative properties. It is still in clinical use today, particularly for depression and sleep disorders.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult subjects after oral administration of doxepin tablets.
