長時間持続性の選択的ヒスタミンH1-受容体アンタゴニスト，メキタジン
Mequitazine is a long-acting and selective histamine H1-receptor antagonist. Mequitazine also possesses antagonistic activity for leukotrienes (LTs) and platelet activating factor (PAF). In the inhibition process, mequitazine acts to inhibit the Ca2+ release from intracellular calcium store of mast cells. Mequitazine is mainly biotransformed by cytochrome P450 2D6 (CYP2D6) in human liver to yield aromatic hydroxylated and S-oxidized metabolites.
