Paliperidone Palmitate is the palmitate ester prodrug of paliperidone, acting as a competitive antagonist of dopamine D2 and 5-HT2A receptors that can cross the blood-brain barrier. It regulates neurotransmitter balance to exert antipsychotic activity. Primarily used in schizophrenia research, it is typically formulated as a long-acting injectable (LAI) that forms a sustained-release depot in the muscle tissue.

| Description | Paliperidone Palmitate is the palmitate ester prodrug of paliperidone, acting as a competitive antagonist of dopamine D2 and 5-HT2A receptors that can cross the blood-brain barrier. It regulates neurotransmitter balance to exert antipsychotic activity. Primarily used in schizophrenia research, it is typically formulated as a long-acting injectable (LAI) that forms a sustained-release depot in the muscle tissue. |
| In vivo | Intramuscular Paliperidone Palmitate forms a long-acting depot lasting ~20 days. Hyaluronidase increases early exposure without compromising the extended-release profile. Injection-site reactions are species-specific (macrophage infiltration in mice vs. granulomas in rats), influencing biphasic absorption kinetics [1][2]. |
