🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionRisperidone is well absorbed after oral administration. Food does not significantly affect the extent of absorption, but may slightly delay the time to peak concentration.
DistributionRisperidone distributes widely throughout the body. It crosses the blood-brain barrier and is also found in breast milk.
Protein BindingApproximately 90% bound to plasma proteins, mainly albumin and alpha-1 acid glycoprotein.
MetabolismRisperidone is extensively metabolized in the liver by CYP2D6 to its active metabolite, 9-hydroxyrisperidone, which has similar pharmacological activity.
Half-LifeThe elimination half-life of risperidone is approximately 3 hours, while the active metabolite 9-hydroxyrisperidone has a half-life of about 24 hours.
ExcretionRisperidone and its metabolites are excreted primarily in the urine (about 70%) and feces (about 15%).
BioavailabilityOral bioavailability of risperidone is approximately 70%.
Onset of ActionInitial effects on agitation and sleep may be seen within a few days, but full antipsychotic effects may take 1 to 2 weeks or longer.
Peak Plasma TimePeak plasma concentration of risperidone is reached within 1 to 2 hours after oral administration. The active metabolite peaks at about 3 to 4 hours.
Duration of ActionThe clinical effects last for about 24 hours, allowing once-daily dosing for most patients.

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

1
D2 receptor blockade: Risperidone binds to dopamine D2 receptors in the mesolimbic pathway, reducing positive symptoms of psychosis.
2
5-HT2A receptor blockade: Blockade of serotonin 5-HT2A receptors helps balance dopamine release and reduces extrapyramidal side effects.
3
Alpha-1 adrenergic blockade: This action can lead to orthostatic hypotension and dizziness.
4
Histamine H1 blockade: Contributes to sedation and increased appetite, leading to weight gain.

Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly 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 ImpairmentDose adjustment is recommended in patients with moderate to severe renal impairment. Start with a lower dose and titrate slowly.
Hepatic ImpairmentDose adjustment is recommended in patients with hepatic impairment. Start with a lower dose and titrate slowly.
Maximum Daily DoseThe 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.
