Tiflorex

Tiflorex, formerly known as flutiorex, is a stimulant amphetamine. Its most pronounced effect is in suppression of appetite; it has little effect on pulse rate, sleep, or mood. It was found to be twice as potent an anorectic as fenfluramine.

SL 72.340-d was cited to be 4x the anorectant potency of fenfluramine (ED50=1.4 mg/kg vs 5.6 mg/kg).
