Clinical Drug Development and Therapeutics
Drug Development is the process of bringing a new pharmaceutical drug to the market once a lead compound has been identified through the process of drug discovery. Drug design often referred to as rational drug design or simply rational design, is the inventive process of finding new medications based on the knowledge of a biological target. The drug is most commonly an organic small molecule that activates or inhibits the function of a biomolecule such as a protein, which in turn results in a therapeutic benefit to the patient. In the most basic sense, drug design involves the design of molecules that are complementary in shape and charge to the biomolecular target with which they interact and therefore will bind to it. The drug is the application of known drugs and compounds to treat new indications. A generic drug is a pharmaceutical drug that is equivalent to a brand-name product in dosage, strength, route of administration, quality, performance, and intended use. The term may also refer to any drug marketed under its chemical name without advertising, or to the chemical makeup of a drug rather than the brand name under which the drug is sold. In drug development, preclinical development, also named preclinical studies and nonclinical studies, is a stage of research that begins before clinical trials can begin, and during which important feasibility, iterative testing and drug safety data are collected.
