Correct answer: A — Atropine or glycopyrrolate
Atropine (0.4-0.6 mg IV/IM) or glycopyrrolate (0.2-0.4 mg IV/IM) are anticholinergic (antimuscarinic) drugs that reduce salivary and bronchial secretions by blocking muscarinic receptors on salivary glands. They may be used as pre-medication before dental sedation or general anaesthesia to improve visualisation and reduce aspiration risk. Glycopyrrolate is preferred because it does not cross the blood-brain barrier (fewer CNS side effects) and has a more potent antisialagogue effect with less tachycardia than atropine.
