Mepyramine is an antihistamine agent used for the symptomatic treatment of allergy, hypersensitivity reactions, and pruritic skin disorders.
Mepyramine is a histamine H1 receptor inverse agonist. It binds to a G protein-coupled form of the receptor and promotes a G protein-coupled inactive state of the H1 receptor that interferes with the Gq/11-mediated signaling. Mepyramine competes with histamine for binding at H-receptor sites on the effector cell surface, resulting in suppression of histaminic edema, flare, and pruritus. The sedative properties of Mepyramine occur at the subcortical level of the CNS.
Indicated for the treatment of allergic conditions, symptomatic relief of hypersensitivity reaction, and treatment of pruritic skin disorders.
