If a patient is given a D2 antagonist and develops extrapyramidal symptoms, what is the recommended treatment?

• A. Lithium
• B. Benadryl
• C. Propranolol
• D. Atropine

Answer: (B)

The recommended treatment for extrapyramidal symptoms caused by a D2 antagonist is Benadryl. Extrapyramidal symptoms often arise due to the blockade of dopamine receptors in the central nervous system, particularly in pathways that control motor function. Benadryl, which contains diphenhydramine, is an antihistamine with anticholinergic properties. This makes it effective in counteracting the symptoms of acute dystonia and other movement disorders associated with dopamine antagonism. Using Benadryl can help relieve symptoms like akathisia, acute dystonic reactions, and parkinsonism that can occur with the administration of D2 antagonists, such as certain antipsychotic medications. This option is favored because of its rapid onset of action in alleviating the discomfort and distress associated with these adverse effects. Though options like lithium and propranolol are useful in managing other conditions—such as mood disorders or hypertension—they are not specifically indicated for the treatment of extrapyramidal symptoms. Atropine, while an anticholinergic, is not commonly used for this purpose as it may not provide the necessary relief for the symptoms linked to D2 antagonism. Thus, Benadryl stands out as the most effective and appropriate choice for this scenario
