Which drug has therapeutic effects including improving rigidity, sialorrhea, muscle relaxation, and sedation?

• A. Benadryl therapeutic effects
• B. Adverse effects
• C. Breast milk effects
• D. Cogentin

Answer: (D)

The main idea is using an anticholinergic medication to counter medication-induced movement disorders (EPS) from antipsychotics. Benztropine, known as Cogentin, blocks muscarinic acetylcholine receptors in the brain, which helps rebalance the dopamine-cholinergic activity in the basal ganglia. This balance reduces rigidity, tremor, and dystonia, and it also decreases salivation, addressing sialorrhea. The drug’s calming, sedating effect can occur with central nervous system anticholinergic activity, which often accompanies its use for EPS. Other options don’t fit this therapeutic role as directly: the other choices are not medications for EPS, and while Benadryl has some anticholinergic effects, it isn’t the standard agent for treating these symptoms.
