Final answer:
The best option for treating side effects of traditional neuroleptics is C. Anticholinergics, as they can counteract the extrapyramidal symptoms that can arise from using these medications.
Step-by-step explanation:
The treatment for side effects of traditional neuroleptics, which are a class of psychotropic medication primarily used for managing psychosis and disorders such as schizophrenia and bipolar disorder, includes options from different classes of medications. Typical side effects can include extrapyramidal symptoms due to dopamine receptor antagonism. To address these, anticholinergics are often used to counteract these effects by reducing the overactivity of acetylcholine that results when dopamine activity is reduced. Beta-blockers are generally not used for this purpose, while benzodiazepines may relieve some acute extrapyramidal symptoms or agitation but are not antidotes to the side effects themselves. ACE inhibitors are classically blood pressure medications and have no role in treating the side effects of neuroleptics.
