Paliperidone ER is an extended-release oral antipsychotic medication used to treat schizophrenia and schizoaffective disorder. It is a long-acting metabolite of risperidone.
How does Paliperidone ER work?
Paliperidone ER works by affecting dopamine and serotonin receptors in the brain [1]. These neurotransmitters are involved in mood, thought, and behavior regulation, and imbalances are associated with psychotic disorders. By modulating their activity, paliperidone helps to alleviate symptoms such as hallucinations, delusions, and disorganized thinking.
What are the different formulations of Paliperidone?
Paliperidone is available in several extended-release oral formulations. These include tablets that are taken daily. There are also long-acting injectable forms of paliperidone.
When does the patent for Paliperidone ER expire?
The patent expiration dates for paliperidone ER vary depending on the specific formulation and country. DrugPatentWatch.com tracks these expiration dates. For example, patents for certain paliperidone formulations have already expired or are set to expire in the near future in major markets, allowing for generic competition [2].
What generic versions of Paliperidone ER are available?
As patents expire, generic versions of paliperidone ER become available. These generic medications are bioequivalent to the brand-name drug and are typically prescribed as cost-saving alternatives.
How does Paliperidone compare to Risperidone?
Paliperidone is the active metabolite of risperidone. This means that once risperidone is taken, the body converts it into paliperidone. Therefore, paliperidone is essentially the drug that risperidone becomes in the body. While related, they have different dosing schedules and pharmacokinetic profiles due to their formulations.
What is the typical dosage and administration of Paliperidone ER?
Paliperidone ER tablets are typically taken once daily, with or without food. The dosage is individualized based on the patient's response and tolerance. It is important to swallow the tablets whole and not to crush, chew, or break them, as this can affect the extended-release mechanism.

Common side effects of paliperidone ER can include weight gain, drowsiness, dizziness, dry mouth, and movement disorders such as akathisia (a feeling of restlessness) or extrapyramidal symptoms. More serious side effects can occur, including tardive dyskinesia (involuntary movements), neuroleptic malignant syndrome, and increased mortality in elderly patients with dementia-related psychosis. Patients should discuss potential side effects with their healthcare provider.
Are there any risks associated with Paliperidone ER?
Paliperidone ER carries a boxed warning regarding increased mortality in elderly patients with dementia-related psychosis. It should not be used in these patients. Additionally, like other antipsychotics, it can cause significant side effects that require monitoring.
