Abstract
This dilemma cased is based on the actual development, FDA approval, and market withdrawal of dexfenfluramine, a drug used in the late 1990s in combination with phentermine for weight loss. The case is set up as a mock trial, with students taking the role of jury, defense (representing the drug company), and the prosecution (representing the central character Sally, who has developed cardiac valvular disease). Developed for a senior-level, small animal science class, the case would be applicable to any science major, and particularly those students who may go on to graduate school or work in research in any of the biomedical fields.
