INFORMATION ABOUT PIMAVANSERIN
Pimavanserin Uses
Pimavanserin is used in the treatment of Parkinson's disease.
How Pimavanserin works
Pimavanserin works by modulating serotonin activity in the brain, specifically at 5-HT₂A receptors, which play a key role in hallucinations and delusions. It does not interfere with dopamine, the chemical essential for movement control. This allows Pimavanserin to effectively reduce hallucinations and delusions in people with Parkinson’s disease psychosis without worsening their motor symptoms.
Common side effects of Pimavanserin
Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
Common
Peripheral edema, Confusion
