PY - 2018 T2 - Poisoning & Drug Overdose, 7e AB - Calcium channel antagonists (also known as calcium channel blockers or calcium antagonists) are widely used to treat hypertension, angina pectoris, coronary spasm, hypertrophic cardiomyopathy, supraventricular cardiac arrhythmias, Raynaud phenomenon, and migraine headache. Toxicity from calcium antagonists may occur with therapeutic use (often owing to underlying cardiac conduction disease or drug interactions) or as a result of accidental or intentional overdose. Overdoses of calcium antagonists are frequently life-threatening and one of the most important sources of drug-induced mortality. As little as one tablet can be potentially life-threatening in a small child.
