Zypadhera, also known by its generic name olanzapine pamoate, is an atypical antipsychotic medication primarily used in the treatment of schizophrenia and bipolar disorder. It is designed for intramuscular injection, providing a long-acting option for patients requiring continuous medication to manage their psychiatric conditions. Zypadhera works by affecting the balance of neurotransmitters in the brain, particularly targeting dopamine and serotonin, to help reduce symptoms such as hallucinations, delusions, and mood swings. This medication is intended for use in adults and is administered by a healthcare professional, offering an alternative for patients who may struggle with adherence to daily oral medication regimens.
