Benztropine (Cogentin) is used to treat the extrapyramidal effects induced by antipsychotics. This drug exerts its effect by:

decreasing the anxiety causing muscle rigidity. blocking the cholinergic activity in the central nervous system (CNS).increasing the level of acetylcholine in the CNS.increasing norepinephrine in the CNS.

Explanation.

Option B is the action of Cogentin. Anxiety doesn’t cause extrapyramidal effects. Overactivity of acetylcholine and lower levels of dopamine are the causes of extrapyramidal effects. Benztropine doesn’t increase norepinephrine in the CNS.
