Glucagon has positive inotropic and chronotropic effects similar to those of beta adrenergic agonists. For comparison, the second drug class with moderate to severe effects were stimulants at 17 percent 2. 50 to 150 mcg/kg bolus slow IV push (3 to 5 mg minimum initial dose), repeat at 5 to 10 minutes. Glucagon for injection (rDNA origin) is a polypeptide hormone identical to human glucagon that increases blood glucose and relaxes smooth muscle of the gastrointestinal tract. A 10-year review (2006 to 2015) of 'double-dose' ingestions from the California Poison Control System revealed that antihypertensives like beta-blockers and calcium channel blockers caused moderate to severe effects in 37 percent of cases. WHAT IS THE TREATMENT FOR BETA BLOCKER OVERDOSE Glucagon. Side effects include dose-dependent nausea and vomiting, hyperglycemia, hypokalemia, and allergic reactions. Answer (1 of 2): For cases of beta-blocker poisoning wherever symptomatic cardiac arrhythmia and cardiovascular disease are present, high-dose glucagon is taken into account the first-line counterpoison. High dose insulin (HDI) (hyperinsulinemia/euglycemia) therapy has emerged from recent clinical and experimental evidence as an effective antidote to calcium. The mechanism of action with HIE for treatment of calcium channel blocker and beta-blocker toxicity is also unknown, although believed to be due to metabolic rescue. Several animal studies and case reports have also demonstrated a benefit in CCB toxicity, though many treatment failures have been noted as well.
Glucagon has shown positive inotropic and chronotropic effects despite beta-receptor blockade in numerous animal models and in humans. Glucagon Glucagon has become an accepted antidote to beta-blocker poisoning because it stimulates cAMP synthesis independent of the beta-adrenergic receptor. 'Pharmacology, pathophysiology and management of calcium channel blocker and beta-blocker toxicity. 11A loading dose of up to 10 mg followed by up to 5 mg/h infusion may be. Glucagon may also be considered in other cases of drug-induced bradycardia. Glucagon is probably the drug of choice to treat massive beta-blocker overdose. It is similar to the usage if insulin in beta blocker overdose. Glucagon has a short half-life and the bolus should be followed by a continuous infusion at 3-5 mg/hr.
