Pimavanserin (pronounced as pima-van-ser-in) is a non-dopaminergic, selective serotonin inverse agonist primarily used for the treatment of Parkinson's disease psychosis and is also being studied for use in other types of psychosis.
Etymology
The name "Pimavanserin" is derived from the chemical structure of the drug. "Pima" refers to the piperidine and methyl components, "van" refers to the vanillyl group, and "serin" refers to the serotonin receptor interaction.
