Biochem/physiol Actions

Prodrug form of paliperidone, is a long-acting injectable antipsychotic that targets dopamine and serotonin receptors.


Paliperidone palmitate is a long-acting injectable form of paliperidone, an atypical antipsychotic that targets dopamine D2 and serotonin 5-HT2A receptors to alleviate schizophrenia symptoms through neurotransmission regulation. Paliperidone palmitate also interacts with α1/α2 adrenergic and H1 histaminergic receptors, influencing both its therapeutic effects and side effect profile. The formulation′s sustained release mechanism promotes gradual absorption, ensuring stable drug levels for prolonged efficacy.

Risperidone is a new benzisoxazole antipsychotic. 9-Hydroxy-risperidone is the major plasma metabolite of risperidone. The pharmacological properties of 9-hydroxy-risperidone were studied and appeared to be comparable to those of risperidone itself, both in respect of the profile of interactions with

This double-blind (DB), randomized, parallel-group study was designed to evaluate efficacy and safety of paliperidone palmitate 6-month (PP6M) formulation relative to paliperidone palmitate 3-month (PP3M) formulation in patients with schizophrenia. Following screening, patients entered an open-label (OL) maintenance phase and
