Calcium may be more effective at improving the blood pressure and the contractility (but less effective at increasing the heart rate). 0000003549 00000 n Nifedipine selectively inhibits calcium ion influx across the cell membrane of vascular smooth muscle and cardiac muscle without altering serum calcium concentrations. They work by blocking some of the calcium that enters the heart and arteries. In general, the following side effects are possible with calcium channel blockers: These medications are more likely to cause: Many calcium channel blockers can cause gingival hyperplasia, which is when your gums grow too much around your teeth. However, there are some conditions, such as arrhythmias or enlarged heart, where you would need to remain on calcium channel blockers (or another medication for that condition) indefinitely. Additionally,CCBs interfere with calcium-stimulated mitochondrial action and glucose catabolism; this results in lactate production and ATP hydrolysis, contributing to acidosis. INDICATIONS AND USAGE: Nimodipine is indicated for the improvement of neurological outcome by reducing the incidence and severity of ischemic deficits in patients with subarachnoid hemorrhage from ruptured intracranial berry aneurysms regardless of their post-ictus neurological condition (i.e., Hunt and Hess Grades I-V).
