experiments using the binding of various ligands for monoamines to rat brain membranes and synaptosomal preparations for studying monoamine uptake and release have shown that d-fenfluramine is more potent than the l isomer in inhibiting 5-ht uptake , whereas d-norfenfluramine preferentially releases 5-ht from a reserpine-insensitive compartment .
