Except for diuretic activity, the mechanism of which is not clearly understood, the pharmacodynamic effects of isradipine observed in whole animals can also be explained by calcium channel blocking activity, especially dilating effects in arterioles which reduce systemic resistance and lower blood pressure, with a small increase in resting heart rate.

The medications may also be prescribed to relieve chest pain (angina) and control an irregular heartbeat. In vitro studies show that the effects of felodipine on contractile processes are selective, with greater effects on vascular smooth muscle than cardiac muscle. Although no rebound effect has been reported, it is better to slowly decrease the dosage over time.

In animal experiments, nimodipine had a greater effect on cerebral arteries than on arteries elsewhere in the body perhaps because it is highly lipophilic, allowing it to cross the blood-brain barrier; concentrations of nimodipine as high as 12.5 ng/mL have been detected in the cerebrospinal fluid of nimodipine-treated subarachnoid hemorrhage (SAH) patients. Heartburn.

In general, calcium channel blockers taken by mouth are safe for long-term use. 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. Monitor and titrate to lowest dose necessary to maintain stable blood pressure. Negative inotropic effects can be detected in vitro, but such effects have not been seen in intact animals. Monitor the patients glucose for hypoglycemia initially every 10 minutes and then every 30 to 60 minutes to maintain glucose between 100 to 200 mg/dL. Studies have demonstrated that the increase in active tension reflects an increase in cytosolic free calcium. They work by preventing calcium from entering the cells of the heart and arteries. Calcium carbonate is cheapest and therefore often a good first . I.V. That slows down those cells use of calcium because there are fewer ways to bring it inside.
