Final answer:
Magnesium sulfate is the recommended medication for treating torsades de pointes, as it helps stabilize the heart's electrical activity.
Step-by-step explanation:
The medication recommended for treating torsades de pointes, which is a specific type of abnormal heart rhythm, is magnesium sulfate. This is different from other conditions such as anaphylactic shock, for which epinephrine would be the drug of choice. Torsades de pointes is a rare but life-threatening heart rhythm disorder and magnesium sulfate is used to stabilize the heart rhythm in this condition. It works by correcting the abnormal electrical activity in the heart. Similarly, in cases of atropine poisoning, a muscarinic agonist would act as the antidote, and anti-anxiety effects might be sought from a class of drugs called benzodiazepines or other anxiolytics. Magnesium sulfate helps to stabilize the electrical activity in the heart and can suppress the abnormal rhythms seen in torsades de pointes.
