Calcium channel blocker toxicity is the taking of too much of the medications known as calcium channel blockers (CCBs), either by accident or on purpose. [3] This often causes a slow heart rate and low blood pressure . [ 1 ]
Amlodipine is a long-acting calcium channel antagonist that selectively inhibits calcium ion influx across cell membranes. [42] It targets L-type calcium channels in muscle cells and N-type calcium channels in the central nervous system which are involved in nociceptive signalling and pain perception.
CCBs are particularly effective against large vessel stiffness, one of the common causes of elevated systolic blood pressure in elderly patients. [4] Calcium channel blockers are also frequently used to alter heart rate (especially from atrial fibrillation), to prevent peripheral and cerebral vasospasm, and to reduce chest pain caused by angina ...
It is a calcium channel blocker of the dihydropyridine type. [2] Nifedipine is taken by mouth and comes in fast- and slow-release formulations. [2] Common side effects include lightheadedness, headache, feeling tired, leg swelling, cough, and shortness of breath. [2] Serious side effects may include low blood pressure and heart failure. [2]
The exact pathophysiology of Monckeberg's arteriosclerosis remains uncertain. However, it is thought that the condition arises from the fatty degeneration of smooth muscle cells within the arterial media, leading to the formation of a mass that undergoes hyaline degeneration and eventually calcification.
Nicardipine, Nifedipine, and Isradipine are calcium channel blockers that work to decrease systemic vascular resistance and subsequently lower blood pressure. Hydralazine and Sodium nitroprusside are systemic vasodilators, thereby reducing afterload, however can be found to have reflex tachycardia, making them likely second or third line choices.
