Glucagon has positive inotropic and chronotropic effects similar to those of beta adrenergic agonists. 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. Side effects include dose-dependent nausea and vomiting, hyperglycemia, hypokalemia, and allergic reactions. High dose insulin (HDI) (hyperinsulinemia/euglycemia) therapy has emerged from recent clinical and experimental evidence as an effective antidote to calcium. Glucagon has also been used in the setting of calcium channel blocker. Several animal studies and case reports have also demonstrated a benefit in CCB toxicity, though many treatment failures have been noted as well. Glucagon is traditionally considered a first line antidote for beta-blocker overdose. 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. Glucagon: Is losing favor as an antidote but can still be used safely. It is similar to the usage if insulin in beta blocker overdose. Severe beta blocker toxicity consists of bradycardia with associated hypotension.
Glucagon, however, has been shown to be effective in treating symptomatic. We therefore investigated hemodynamic effects and safety of high-dose glucagon with and without con-comitant beta-blockade. This is true of most antidotes because of ethical constraints on toxicology studies. The links at the bottom will expand further. BACKGROUND: Intravenous high-dose glucagon is a recommended antidote against beta-blocker poisonings, but clinical ef-fects are unclear. Though they are two separate classes of drugs, both beta blocker and calcium channel blocker poisonings present with hypotension, bradycardia, heart block, and.
