Which drug is used for sialorrhea in Parkinsonism as part of its therapeutic effects?

• A. Benadryl
• B. Cogentin
• C. Benadryl adverse effects
• D. Adverse effects

Answer: (B)

Excess saliva in Parkinsonism can be helped by drugs that reduce secretions through anticholinergic action. Cogentin, which is benztropine, blocks muscarinic acetylcholine receptors, lowering parasympathetic activity and thus reducing saliva production. This makes it effective for sialorrhea as part of treating parkinsonian symptoms. Benadryl (diphenhydramine) does have anticholinergic effects but is not used to manage drooling in Parkinsonism and can cause sedation and cognitive issues, especially in older patients. The other options aren’t medications designed to treat this symptom.
