Prolonged Inhibition of Vascular Contraction and Calcium Influx by the Novel 1, 4-Dihydropyridine Calcium Antagonist Cinaldipine (FRC-8653)

[摘要] References(15)Cited-By(24)We examined the effects of FRC-8653, a novel dihydropyridine calcium antagonist, on the contraction of an arterial preparation and the calcium influx into vascular smooth muscle cells to clarify the long-lasting hypotensive activity of this drug. Inhibition by FRC-8653 persisted for more than 7 hr after its removal, whereas nifedipine and nicardipine exhibited shorter durations of suppressive activity. These results suggest that prolonged inhibition of calcium influx through L-channels contributes to the long-lasting vasodilative and antihypertensive activity of FRC-8653.
