Isradipine is a dihydropyridine calcium channel blocker used primarily for the management of hypertension (high blood pressure). It acts by relaxing vascular smooth muscle, leading to decreased peripheral resistance and lowered blood pressure. Isradipine was previously approved and marketed for clinical use but is now discontinued in several countries, including the United States.
Pharmacokinetics
Pharmacokinetic parameters reported for healthy adult volunteers following oral administration of immediate-release isradipine tablets.
