Which antipsychotic medication is a partial agonist at the D2 receptor, often referred to as a 'dopamine stabilizer'?
Show answer and explanation
Correct answer: Aripiprazole
Aripiprazole acts as a partial agonist; it reduces dopaminergic activity when dopamine levels are high (mesolimbic) and increases it when levels are low (mesocortical). This unique profile helps balance efficacy with a lower risk of extrapyramidal symptoms.
