Stereoselective disposition of fenfluramine enantiomers in the rat. 1978

A Jori, and P De Ponte, and S Caccia

1. Rats were treated with d-, l-or dl-fenfluramine. The two optical isomers and their metabolites were determined in plasma, red blood cells and brain areas such as striatum and brainstem. 2. In all cases, the levels of d-fenfluramine were higher than those of the l-enantiomer, while levels of the metabolite norfenfluramine were lower for the d- than the l-form. 3. When metabolism of fenfluramine was inhibited by pre-treatment with SKF 525-A, the concentrations of the enantiomers no longer differed.

D003342	Corpus Striatum	Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.
