Cloforex (Oberex) is an anorectic of the amphetamine class.[1] It is a prodrug to chlorphentermine.[2] It never became a mass produced drug in part due to the side effects found in mice. Mice who consumed 75 mg of cloforex a day experienced weight loss along with pulmonary hypertension and hair loss.[3]
