A pharmaceutical drug (medicine or medication and officially medicinal product) is defined as a drug used in health care. Such drugs aid the diagnosis, cure, treatment, or prevention of disease. Drug therapy (pharmacotherapy) is an important part of the medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management. Drug discovery and drug development are complex and expensive endeavors undertaken by pharmaceutical companies, academic scientists, and governments. Governments generally regulate what drugs can be marketed, how drugs are marketed, and in some jurisdictions, drug pricing. Controversies have arisen over drug pricing and disposal of used drugs.
In the United States a Drug is Defined as:
Effective drug regulation on the part of nations both promotes and protects the health of the public through ensuring several things. Medicines that are of adequate quality, are safe and efficient are required. Health care professionals and patients must have the needed information to enable them to use the medications rationally. Medicines must be manufactured, stored, distributed and dispensed in appropriate manners. Any illegal manufacture and trade of drugs must be both detected and adequately sanctioned. Promotion and advertising of drugs must be balanced, fair and aimed at the rational use of drugs. Access to medications must not be hindered by unjustified regulatory work.
National governments are held responsible for the establishment for strong national drug regulation authorities (DRA's) that have a clear mission, realistic objectives, a solid legal basis, an appropriate organizational structure, suitable financing, an appropriate level of qualified staff, equipment and information, access to technical literature, and the capacity to exert effective market control. DRA's are accountable to both the government and the public at large for their decisions and should be transparent. The DRA's evaluation and monitoring mechanisms need to be built into its regulatory system to assess attainment of its established objectives.
