Ganglionic Blockers · Pharmacology

Which mechanism best explains the action of ganglionic blocking drugs?

  1. Inhibition of acetylcholine synthesis in preganglionic neurons
  2. Irreversible blockade of muscarinic receptors
  3. Activation of alpha adrenergic receptors
  4. Competitive blockade of nicotinic receptors in ganglia
Show answer and explanation

Correct answer: Competitive blockade of nicotinic receptors in ganglia

Ganglionic blockers act by competitively inhibiting nicotinic acetylcholine receptors in autonomic ganglia. This prevents synaptic transmission between preganglionic and postganglionic neurons.
