Aripiprazole is classified as which type of antipsychotic?

• A. Typical antipsychotic
• B. Atypical (second generation) antipsychotic
• C. Antidepressant
• D. Mood stabilizer

Answer: (B)

Aripiprazole falls into the atypical (second generation) antipsychotics because these drugs combine dopamine receptor modulation with serotonin receptor effects, giving them a broader action than older, typical antipsychotics that mostly block D2 alone. Aripiprazole is unique in that it acts as a partial agonist at dopamine D2 receptors, which helps dial down excessive dopamine signaling associated with psychotic symptoms without fully blocking dopamine and triggering movement problems. It also targets serotonin receptors, acting as a partial agonist at 5-HT1A and an antagonist at 5-HT2A receptors. This combination tends to reduce positive symptoms while posing fewer extrapyramidal side effects than typical antipsychotics and can help with mood and cognitive aspects, which is characteristic of atypical antipsychotics rather than antidepressants or mood stabilizers.
