Nov. 5, 2008 -- Two banned obesity drugs may have lingering effects on the heart, according to a new study. The study shows that heart valve problems linked to the banned obesity drugs fenfluramine and/or dexfenfluramine typically last years after stopping those drugs. The FDA ordered fenfluramine and dexfenfluramine off the market in September 1997 after those drugs were linked to heart valve problems. Fenfluramine was one of the ingredients in fen-phen , and dexfenfluramine is closely related to fenfluramine.
Biological engineers or bio-engineers are engineers who use the principles of biology and the tools of engineering to create usable, tangible, economically viable products.
Also, they frequently work in research and development or in quality assurance. Biomedical engineers design electrical circuits, software to run medical equipment, or computer simulations to test new drug therapies. They also design and build artificial body parts such as hip and knee joints.iomedical engineers use the principles of calculus and other advanced topics in mathematics for analysis, design, and troubleshooting in their work. Problem-solving skills. Biomedical engineers typically deal with and solve problems in complex biological systems.
