Question

A patient presents in the Emergency Department in great distress and with the following signs and symptoms: Which drug most likely caused these signs and symptoms?

A. AChE inhibitor
B. α-adrenergic blocker
C. Antimuscarinic
D. β-adrenergic blocker
E. Parasympathomimetic (muscarinic agonist)
F. Peripherally acting (neuronal) catecholamine depletor

Answer 1

Antimuscarinic drugs most likely caused the signs and symptoms described.

Step-by-step explanation:

The signs and symptoms described, such as distress and affected interaction with the organ, are consistent with anticholinergic toxicity. Therefore, the drug most likely to have caused these signs and symptoms is C. Antimuscarinic. Anticholinergic drugs block muscarinic receptors, suppressing parasympathetic interaction with the organ.
