![]() For cases of CCB poisoning where cardiotoxicity is evident, a combination of calcium and epinephrine should be used initially, reserving HDIDK for refractory cases. For cases of beta-blocker poisoning where symptomatic bradycardia and hypotension are present, high-dose glucagon is considered the first-line antidote. It is very costly Unless you are a cancer center, you likely won’t carry this antidote but should have a system in place to obtain it if needed. Health-system pharmacists should be aware that when these drugs are used as antidotes, higher than normal dosing is needed.ĬONCLUSION: Poisoning by beta-blockers or CCBs usually produces hypotension and bradycardia, which may be refractory to standard resuscitation measures. Glucagon 20 x 1 mg Y Y Glucarpidase 5 x 1000 units/vial N N This is the antidote for catastrophic methotrexate poisoning or inadvertent overdoses of methotrexate. For cases of CCB poisoning where cardiotoxicity is evident, first-line therapy is a combination of calcium and epinephrine high-dose insulin with supplemental dextrose and potassium therapy (HDIDK) is reserved for refractory cases. Beta Blockers (end with lol.Atenolol, Metoprolol, etc.)) -> Glucagon Anticholinergic Toxicity (various medications can lead to this that cause anticholinergic effectsantihistamines, atropine, etc. Traditionally, antidotes for CCB overdose have included calcium, glucagon, adrenergic drugs, and amrinone. However, in beta-blocker poisoning where symptomatic bradycardia and hypotension are present, high-dose glucagon is considered the first-line antidote. Therapies include beta-agonists, glucagon, and phosphodiesterase inhibitors. Poisoning by CCBs is characterized by cardiovascular toxicity with hypotension and conduction disturbances, including sinus bradycardia and varying degrees of atrioventricular block. Does Glucagon Really Work for Beta Blocker Overdose December 2022 Authors: Joanne C. The common feature of beta-blocker toxicity is excessive blockade of the beta-receptors resulting in bradycardia and hypotension. In overdose, beta-blockers and CCBs have similar presentation and treatment overlaps and are often refractory to standard resuscitation measures. Beta-blockers and CCBs represent the most important classes of cardiovascular drugs. SUMMARY: Overdoses with cardiovascular drugs are associated with significant morbidity and mortality. ![]() PURPOSE: The toxic effects and treatment of beta-adrenergic blocker and calcium-channel blocker (CCB) overdose are reviewed.
