A systematic review was done in order to evaluate the evidence supporting glucagon use in β‐blocker and calcium channel blocker overdoses. 2004-11-01 Anecdotal reports on the use of glucagon have failed to show significant hemodynamic improvement. We report the first case of calcium channel blocker overdose that responded to glucagon. We conclude that glucagon is safe and effective in the management of hemodynamic instability associated with calcium channel blocker poisonings. Beta blockers act by antagonizing myocardial beta-1 adrenoreceptors, reducing the entry of calcium into cardiomyocytes produced by cAMP, causing negative chronotropic and ionotropic effects. If GI decontamination is no longer an option, additional therapies for beta blocker poisoning can be given to improve myocardial contractility and bradycardia through alternative pathways.
