Cơ Chế Tác Dụng :
Mepyramine (also known as pyrilamine) is a first generation antihistamine, targeting the H1 receptor. However, it rapidly permeates the brain and so often causes drowsiness as a side effect.
It is used in over-the-counter combination products for colds and menstrual symptoms.
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 H1-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.
Độc Tính :
The signs and symptoms that are produced after the acute overdosage of Mepyramine include Convulsions, Coma, Ataxia, Hyperpyrexia, Tremor, Extrapyramidal effects, Excitement.
Chỉ Định :
Mepyramine is a first generation antihistamine used in treating allergies, ymptomatic relief of hypersensitivity reaction, and in pruritic skin disorders.
