What drugs are combined in Duodote?

• A. Pralidoxime and atropine
• B. Atropine and morphine
• C. Pralidoxime and diazepam
• D. Atropine and epinephrine

Answer: (A)

Duodote is the antidote for organophosphate poisoning and combines two drugs: atropine and pralidoxime. Atropine blocks acetylcholine at muscarinic receptors, so it relieves the life-threatening secretions, bronchoconstriction, bradycardia, and other muscarinic effects. Pralidoxime reactivates acetylcholinesterase by removing the organophosphate inhibitor from the enzyme, helping restore nerve signaling and reducing both muscarinic and nicotinic symptoms, especially muscle weakness. This pairing specifically addresses the two major pathways of organophosphate toxicity. The other drugs listed are not part of Duodote and are used for different indications (pain relief, seizures/anxiety, or anaphylaxis/shock).
