Doxepin is a tricyclic antidepressant (TCA) used in the treatment of various mental health conditions, including depression and anxiety. Structurally, it is a dibenzoxepin derivative. Doxepin works by inhibiting the reuptake of neurotransmitters such as serotonin and norepinephrine in the brain, thereby increasing their levels and improving mood. Additionally, doxepin acts as an antagonist at histamine H1 receptors, contributing to its sedative effects. Administered orally, doxepin is valued for its efficacy in managing symptoms associated with mood disorders and certain anxiety conditions. Its dual mechanism of action sets it apart within the tricyclic antidepressant class, providing a versatile approach to mental health treatment.
