Tiflorex (also known as (+)-Flutiorex) is a phenylalkylamine derivative patented by Synthelabo S. A. as an anorectic agent. Tiflorex acts as a central nervous system stimulant form amphetamine class with little effect on pulse rate, sleep, or mood. In preclinical models, Tiflorex provoked a dose-dependent reduction in the consumption of the protein-rich diet and a reduction in the consumption of the protein-poor diet.
