Description and Uses

Doxepin is a tricyclic antidepressant that binds to the serotonin (5-HT) transporter (SERT) and norepinephrine transporter (NET; K_ds = 68 and 29.5 nM, respectively). It is a histamine H₁ receptor antagonist (K_i = 1.23 nM). Doxepin selectively binds to SERT and NET over the dopamine transporter (DAT; K_d = 12,100 nM) and inhibits histamine H₁ over H₂, H₃, and H₄ receptors (K_is = 170, 39,810, and 15,135 nM, respectively). It also binds to the 5-HT₂ receptor, as well as to muscarinic acetylcholine and α₁-adrenergic receptors (α₁-ARs; K_ds = 27, 23, and 23.5 nM, respectively). Doxepin (10 mg/kg, i.p.) decreases allodynia and hyperalgesia in a mouse model of chronic constriction injury-induced neuropathic pain. It increases the distance traveled in the center of the open field test and reduces immobility time in the forced swim test in a mouse model of depression induced by chronic stress when administered orally at a dose of 15 mg/kg. Formulations containing doxepin have been used in the treatment of depression and insomnia.

Doxepin is used clinically to treat anxiety and depression. Doxepin is an antidepressant.
