All CCBs are very well absorbed orally across the subtypes, undergo extensive hepatic first-pass metabolism, are lipophilic, bind readily to plasma proteins, and have a large volume of distribution (> 2 liters/kg). Your doctor may prescribe both a CCB and another hypertensive drug at the same time. Conventional decontamination measures like urinary alkalinization, hemodialysis, or hemofiltration are ineffective in CCB toxicity because of their large volume of distribution and lipophilic nature.

Although like other dihydropyridine calcium channel blockers, isradipine has negative inotropic effects in vitro, studies conducted in intact anesthetized animals have shown that the vasodilating effect occurs at doses lower than those which affect contractility. Progressive deterioration reverses this trend, and patients with severe renal failure (creatinine clearance < 10 mL/min) who have been on hemodialysis show a 20% - 50% lower AUC than healthy volunteers. 0000030440 00000 n (dilute to 0.1 mg/mL): Acute hypertension: Initial: 5 mg/hour increased by 2.5 mg/hour every 15 minutes to a maximum of 15 mg/hour; consider reduction to 3 mg/hour after response is achieved.

At higher doses clearance slows, because hepatic clearance changes from first-order to zero-order kinetics. Too much amlodipine can cause your blood pressure to drop too low. The effect of felodipine on blood pressure is principally a consequence of a dose-related decrease of peripheral vascular resistance in man, with a modest reflex increase in heart rate. Nifedipine is a peripheral arterial vasodilator which acts directly on vascular smooth muscle. In a study of patients with cirrhosis, diltiazem's half-life was increased, and there was a 69% increase in AUC compared to patients with normal liver function. Conversion from I.V. 0000200357 00000 n Mechanism of Action: Nimodipine is a calcium channel blocker.

Calcium channel blockers lower blood pressure and treat other conditions such as chest pain and an irregular heartbeat. With the exception of a mild diuretic effect seen in several animal species and man, the effects of felodipine are accounted for by its effects on peripheral vascular resistance.
