Doxepin hydrochloride is a highly potent Histamine H1 Receptor (histamine H1) antagonist. Doxepin hydrochloride also binds to histamine H4 receptor. Doxepin hydrochloride is an inhibitor of AR and mAChR. Doxepin Hydrochloride is a dibenzoxepin analogue and tricyclic antidepressant with antipruritic and sedative activities. Doxepin also has antagonistic effects on histamine (H1 and H2), 5-HT2, alpha-1 adrenergic, and muscarinic receptors. The antipruritic effect of this agent is the result mediated through inhibition of histamine receptors. References: Rahman N, Siddiqui S, Azmi SN.
