Q: How does Invega work?

Mechanism of Action Invega, which contains the active ingredient paliperidone, works by altering the activity of certain natural substances in the brain called neurotransmitters. These chemicals are responsible for sending signals between nerve cells and play a significant role in mood, behavior, and thought processes. The medication primarily targets two specific neurotransmitters: Dopamine: It helps regulate the overactivity of dopamine, which is often linked to symptoms like hallucinations and delusions. Serotonin: It also affects serotonin levels, which can help improve mood, cognitive function, and social interaction. While the exact way Invega works is not fully understood, researchers believe it functions by blocking specific receptors for these chemicals on the surface of brain cells. By modulating these pathways, the medication helps to decrease abnormal excitement in the brain and restore a more stable chemical balance.
