Pharmaceuticals are medicinal drugs that are regulated by the U.S. Food and Drug Administration (FDA) or other regulatory bodies and are manufactured by pharmaceutical companies. Pharmaceutical scientists are typically involved in the development of new drugs: discovery, drug delivery systems, drug absorption and distribution, metabolism, and elimination characteristics. They spend most of their time doing research in a laboratory or office setting. Pharmacists also work with existing drugs, patients, and other healthcare practitioners to optimize patient care and drug use. They often work face-to-face with physicians (drug selection and use) and patients (best use of medications).
Biotechnology (commonly referred to as biotech) is the use of biological research techniques to develop products and processes based on genetically manipulated compounds from living organisms. Biotech is the applied knowledge of biology and seeks to duplicate or change the function of a living cell so it will work in a more predictable and controllable manner. Currently, the most common applications of biotech can be found within medicine and agriculture, as well as within industrial process and environmental undertakings. Biotech and pharmaceutical industries are similar, with the exception that biotech firms are more centered on research to develop their initial products.
