Description

Altanserin is a potent and selective 5-HT2A receptor antagonist. Serotonin (5-HT) system functioning have been proposed for a variety of psychiatric disorders, but a direct method quantitatively assessing 5-HT release capacity in the living human brain is still lacking. It was suggested that the combination of a dexfenfluramine-induced 5-HT release and subsequent assessment of 5-HT(2A) receptor availability with [(18)F]altanserin by positron emission tomography (PET) was suitable to measure cortical 5-HT release capacity in the human brain. Besides human neuroimaging studies altanserin has also been used in the study of rats.

In Vivo Use Guide

Thirteen healthy male subjects received placebo and single oral doses of 40 mg (n = 6) or 60 mg (n = 7) of the potent 5-HT releaser dexfenfluramine separated by an interval of 14 days. Three further subjects received placebo on both days. Two hours after placebo/drug administration, 250 MBq of the 5-HT(2A) receptor selective PET-radiotracer [(18)F]altanserin was administered intravenously as a 30s bolus.

Route of Administration: Intravenous
