Benidipine hydrochloride is a new, long acting dihydropyridine calcium antagonist useful in the treatment of hypertension and angina pectoris. In experimental animals,
benidipine hydrochloride dose dependently induced hypotension with a potency of
6 and 12 times more than nifedipine and nicardipine, respectively. It also exhibited a
slow onset of action.
Benidipine is an orally bioavailable blocker of L-, T-, and N-type calcium channels. In guinea pig ventricular cells benidipine has an IC50 of 2.7 nM for calcium currents, determined using whole cell voltage clamp electrophysiology. It prevents oxidative stress dose-dependently in vitro, decreases blood pressure in spontaneously hypertensive rats (at 3 and 10 mg/kg), and is neuroprotective for neural stem cells after oxidative stress-induced injury. Benidipine is also a competitive antagonist at mineralocorticoid receptors.
Yellow Crystalline Powder
A dihydropyridine calcium channel blocker. Antihypertensive.
Orally active antihypertensive agent which displays a wide range of activities in vitro and in vivo . Inhibits L-, N- and T-type Ca 2+ channels. Also inhibits aldosterone-induced mineralocorticoid receptor activation. Exhibits cardioprotective and antiartherosclerotic effects.
A poison by ingestion,intraperitoneal, and intravenous routes. When heated todecomposition it emits toxic vapors of NOx and HCl.
