A patient with severe beta blocker poisoning has marked bradycardia and hypotension despite initial intravenous fluids. Which medicine is commonly prepared as part of emergency treatment?
Correct answer: A. Glucagon
- A. Glucagon
- B. Flumazenil
- C. Methylene blue
- D. Pyridoxine
Explanation
Glucagon can improve heart rate and contractility in significant beta blocker toxicity because it increases intracellular cyclic AMP through a pathway separate from the beta receptor. Flumazenil reverses benzodiazepines, while methylene blue and pyridoxine treat different toxic exposures.
