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 ]
Calcium channel blockers (CCB), ... If the time of the overdose is known and presentation is within two hours of ingestion, activated charcoal, gastric lavage, ...
Calcium channel blockers (CCBs) preferentially block the L-type voltage-gated calcium channels to prevent the flow of calcium influx in the blood vessels and the heart, thereby reducing peripheral vascular resistance and cardiac output respectively. [10] Dihydropyridines (DHP): amlodipine, nifedipine, felodipine, nicardipine
Amlodipine is an angioselective calcium channel blocker and inhibits the movement of calcium ions into vascular smooth muscle cells and cardiac muscle cells which inhibits the contraction of cardiac muscle and vascular smooth muscle cells. Amlodipine inhibits calcium ion influx across cell membranes, with a greater effect on vascular smooth ...
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]
Other causes include other forms of hypoparathyroidism, vitamin D deficiency, kidney failure, pancreatitis, calcium channel blocker overdose, rhabdomyolysis, tumor lysis syndrome, and medications such as bisphosphonates or denosumab. [1] Diagnosis should generally be confirmed by determining the corrected calcium or ionized calcium level. [2]
Itraconazole also inhibits an important cytochrome liver enzyme (CYP 450 3A4) which is needed to metabolize isradipine and other calcium channel blockers. This will increase plasma levels of isradipine and could cause an unintentional overdose of the medication. Caution is advised when administering both agents together.
