True or False: Agonist neuromuscular blockers are classified as nondepolarizing agents.

• A. True
• B. False
• C. Depends on the dosage
• D. They can be both

Answer: (B)

Agonist neuromuscular blockers are classified as depolarizing agents rather than nondepolarizing agents. In pharmacology, nondepolarizing neuromuscular blockers act by competitively inhibiting the binding of acetylcholine to nicotinic receptors at the neuromuscular junction, leading to muscle relaxation. In contrast, depolarizing neuromuscular blockers, such as succinylcholine, act as agonists by initially stimulating the receptor, causing muscle contraction, but then remain bound, preventing further transmission of impulses and effectively causing a state of paralysis. Given this understanding, the statement that agonist neuromuscular blockers are classified as nondepolarizing agents is false. The classification is based on their mechanism of action and effects on neuromuscular transmission, which clearly distinguishes agonist from nondepolarizing neuromuscular blockers.
