Description
Paliperidone is a psychotropic agent belonging to the chemical class of benzisoxazole derivatives. Paliperidone is the major active metabolite of Risperidone. It is a centrally active dopamine Type 2 (D2) antagonist and with predominant serotonin Type 2 (5-HT2A) antagonist activity. It is also active as an antagonist at α1 and α2 adrenergic receptors and H1 histaminergic receptors, which may explain some of the other effects of the drug. It has no affinity for cholinergic muscarinic or β1-and β2-adrenergic receptors.

Precautions
Caution should be exercised when Paliperidone is prescribed in patients with known Cardiovascular diseases, QT prolongation, Neuroleptic malignant syndrome, Tardive dyskinesia, Hyperglycemia, Dyslipidemia, Obesity, Hyperprolactinemia, Leukopenia, Neutropenia, Agranulocytosis, Seizures, Potential for Cognitive & Motor impairment etc.
Use in Pregnancy & Lactation
Pregnancy: Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Paliperidone should be used during pregnancy only if the potential benefits justifies the potential risk to the fetus.
Lactation: Paliperidone is excreted in human breast milk. The known benefits of breastfeeding should be weighed against the unknown risks of infant exposure to Paliperidone.
Pediatric use
Safety and effectiveness in the treatment of schizophrenia not established in patients less than 12 years of age. Safety and effectiveness in the treatment of schizoaffective disorder not established in patients less than 18 years of age.
Drug Interaction
• Paliperidone should be used with caution in combination with other centrally acting drugs and alcohol. It may antagonize the effect of Levodopa and other dopamine agonists.
• Because of its potential for inducing orthostatic hypotension, an additive effect may be observed when Paliperidone is administered with other therapeutic agents that have this potential.
• Strong CYP3A4/P-glycoprotein (P-gp) inducers: It may be necessary to increase the dose of Paliperidone when a strong inducer of both CYP3A4 and P-gp (e.g., carbamazepine) is co-administered. Conversely, on discontinuation of the strong inducer, it may be necessary to decrease the dose of Paliperidone.
• Co-administration of divalproex sodium increased Cmax and AUC of Paliperidone by approximately 50%. Adjust dose of Paliperidone if necessary based on clinical assessment.
Over Dose
Overdose of Paliperidone is limited; there is no specific antidote to Paliperidone. If overdose occurs general supportive and symptomatic measures should be employed.
