Final answer:
Dystonic reactions are treated with anticholinergic drugs. Commonly used drugs with dopamine antagonist properties include typical and atypical antipsychotic medications.
Step-by-step explanation:
Dystonic reactions are treated by administration of anticholinergic drugs. These drugs act by inhibiting the effects of acetylcholine, a neurotransmitter involved in muscle movement. Some commonly used anticholinergic drugs for treating dystonic reactions include diphenhydramine (Benadryl), benztropine (Cogentin), and trihexyphenidyl (Artane).
Drugs with dopamine antagonist properties that are commonly used in clinical practice include typical antipsychotic medications such as haloperidol (Haldol) and chlorpromazine (Thorazine), as well as atypical antipsychotic medications such as risperidone (Risperdal) and olanzapine (Zyprexa).
