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.
