Cholinergic Blocking Drugs

Question 1

Cholinergic-Blocking Drugs

Answer 1

• Drugs that block or inhibit the actions of acetylcholine (ACh) in the parasympathetic nervous system (PSNS)
• Also known as anticholinergics, parasympatholytics, and antimuscarinic drugs

Question 2

AntiCholinergics

Mechanism of Action

Answer 2

• Competitive antagonists
• Compete with ACh for binding at muscarinic receptors in the PSNS——-As a result, ACh is unable to bind to thereceptor site and cause a cholinergic effect
• Once these drugs bind to receptors, they inhibit nerve transmission at these receptors
