🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Risperidone is an atypical antipsychotic that works by blocking dopamine D2 receptors and serotonin 5-HT2A receptors in the brain. This dual antagonism helps reduce positive symptoms of schizophrenia such as hallucinations and delusions, while also improving negative symptoms and mood. It also blocks alpha-adrenergic receptors, which can cause orthostatic hypotension, and histamine H1 receptors, which contributes to sedation and weight gain.
Mechanism Steps
💡 How to Take Ris 4mg Tablet
Strength: Risperidone 4 mg immediate-release tablet
Dosage Information
| Adult Dosage | The usual starting dose for schizophrenia is 2 mg once daily, which may be increased to 4 mg or higher based on response and tolerability. For bipolar mania, the typical starting dose is 2 to 3 mg once daily. For irritability associated with autism, dosing is individualized based on weight. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may require lower starting doses and slower titration due to increased sensitivity to side effects. Use with caution in elderly patients with dementia due to increased risk of stroke and mortality. |
| Renal Impairment | Dose adjustment is recommended in patients with moderate to severe renal impairment. Start with a lower dose and titrate slowly. |
| Hepatic Impairment | Dose adjustment is recommended in patients with hepatic impairment. Start with a lower dose and titrate slowly. |
| Maximum Daily Dose | The maximum recommended daily dose is 16 mg, but doses above 6 mg per day do not consistently provide additional benefit and may increase side effects. |
