How it works

From the US prescribing label for the same active substance (PALIPERIDONE). It describes the substance, not this exact product.

Paliperidone is the major active metabolite of risperidone.

The mechanism of action of paliperidone in schizophrenia is unclear.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.
How the body breaks it down

Metabolism and Elimination Although in vitro studies suggested a role for CYP2D6 and CYP3A4 in the metabolism of paliperidone, in vivo results indicate that these isozymes play a limited role in the overall elimination of paliperidone [see Drug Interactions (7) ].

How it leaves the body

One week following administration of a single oral dose of 1 mg immediate-release 14 C-paliperidone to 5 healthy volunteers, 59% (range 51% - 67%) of the dose was excreted unchanged into urine, 32% (26% - 41%) of the dose was recovered as metabolites, and 6% - 12% of the dose was not recovered.

With food

Administration of a 12 mg paliperidone extended-release tablet to healthy ambulatory subjects with a standard high-fat/high-caloric meal gave mean C max and AUC values of paliperidone that were increased by 60% and 54%, respectively, compared with administration under fasting conditions.
