Same patient with dry mouth. Which medication could help this condition?
Show answer and explanation
Correct answer: A. Muscarinic receptor agonist
- A. Correct. Muscarinic agonists such as pilocarpine and cevimeline stimulate residual salivary gland function and increase salivary flow.
- B. A muscarinic ANTAGONIST (anticholinergic) would dry the mouth further — the opposite of what's needed.
- C. Beta blockers do not stimulate salivation and can contribute to dryness.
- D. Alpha-adrenergic agonists do not increase aqueous salivary flow in this setting.
