Cayman Manidipine

Manidipine is a dihydropyridine L- and T-type calcium channel blocker.^,, It blocks recombinant rabbit L-type (α_1Cα₂/δβ_1a) and human T-type (α_1H) calcium channels expressed in Xenopus oocytes and native L-type channels in dissociated guinea pig cardiac ventricular cells (IC₅₀ = 2.6 nM). Manidipine inhibits intracellular calcium increases induced by endothelin-1 (ET-1; Item No. ) in A₇r₅ rat vascular smooth muscle cells (ED₅₀ = 1 nM) and potassium-induced contraction of isolated dog femoral and portal veins (IC₅₀s = 24 and 2.1 nM, respectively).^, In vivo, it lowers blood pressure in spontaneously hypertensive rats (SHRs) when administered at a dose of 10 mg/kg and inhibits left ventricular hypertrophy in rats induced by isoproterenol (Item No. ) when administered at a dose of 3 mg/kg.^, Formulations containing manidipine have been used in the treatment of hypertension.
