Y1 - 2015 N1 - T2 - Goldfrank's Toxicologic Emergencies, 10e AB - The traditional role of glucagon was to reverse life-threatening hypoglycemia in patients with diabetes unable to receive dextrose in the outpatient setting. However, in medical toxicology, glucagon is used “off label” early in the management of β-adrenergic antagonist and calcium channel blocker toxicity to increase heart rate, contractility, and blood pressure by increasing myocardial cyclic adenosine monophosphate (cAMP) via a non–β-adrenergic receptor mechanism of action. The use of glucagon is based primarily on animal studies and as well as human case series and case reports. The effects of glucagon are often transient.
