Therapeutic Class

Atypical Neuroleptic / Second-Generation Antipsychotic

Pharmacology

Risperidone is a selective monoaminergic antagonist with high affinity for dopamine D2 and serotonin 5-HT2A receptors. It also has moderate activity at alpha1-adrenergic and H1 histamine receptors, while having minimal anticholinergic effects. This balanced receptor activity helps alleviate positive symptoms of schizophrenia while also improving negative and affective symptoms, and it generally carries a lower risk of extrapyramidal side effects compared to typical antipsychotics. Risperidone modulates dopamine and serotonin pathways in the brain, stabilizing mood and behavior.

Dosage and Administration

Schizophrenia:

• Initial: 1 mg twice daily

• Gradual increase by 1 mg increments, as tolerated

• Usual maintenance: 4–6 mg daily; maximum: 16 mg/day

Mania in Bipolar Disorder:

• Initial: 2–3 mg daily

• Adjust according to response and tolerability

• Maximum dose: 6–8 mg/day

Elderly or patients with hepatic/renal impairment:
