Biopharmaceutics is the study of biopharmaceuticals, or medical drugs that are produced using biotechnology. It is a discipline that studies the disposition of a drug in the body based on the drugââ¬â¢s physicochemical properties and their interaction with the biological platform, as related to the inception, duration, and intensity of drug action, including co-constituents and mode of manufacture and form of administration of a drug. A basic assumption of people in the pharmaceutical industry (>85% in survey), in the U.S., is that the biopharmaceutical is a part of pharmaceutical, i.e., the biopharmaceuticals are pharmaceuticals that are biological in nature and manufactured using biotechnology, while drugs are the other major pharmaceuticals, with the source and manufacturing being non-biological in nature. The large majority of biopharmaceutical products are derived from life forms. In drug industry some small molecule drugs are not regarded as biopharmaceutical in nature. Systematic investigation of the biopharmaceutical properties of a drug is essential to determine the proper route of administration and most suitable delivery system for the drug. With the Biopharmaceutical Classification System for drugs over the past decade, the better strategies of formulation development based on the solubility and permeability of the drugs has been developed. A newly developed pattern, Biopharmaceutical Drug Disposition Classification System, has also integrated the physical concept of solubility and permeability to the effect of transporters and the predominate route of elimination of the drug.
