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.
