Medicinal biotechnology aims to produce pharmaceutical and diagnostic products for the prevention and treatment of human diseases using living cells and cell materials. The areas of application of medicinal biotechnology are genetic testing, drug production, gene therapy and pharmacogenomics. One of the major uses in biotechnology is for medicinal purposes. Modern applications of biotechnology continue to find promising new uses in the medicinal and health care fields. Modern biotechnology can be used to manufacture drugs more easily and cheaply, as they can be produced in larger quantities from existing genetic sources.
