At a time when the production and distribution of drugs and drug products is no longer confined within the national boundaries of particular countries, many thoughtful people are concerning themselves with the idea of standardisation of quality control procedures and specifications. For medicines currently marketed in different countries, a multitude of standards and specifications for both the raw materials and finished products exists. Plans for the regionalisation of drug standards have been put into operation but realistic estimates of progress agree that it will be measured and dignified. In one area there is the possibility for earlier action in reaching agreement on adequate specifications. The process of registration of a new drug substance for the first time presents an opportunity to make known to drug regulation authorities, academic and industrial pharmaceutical specialists, and other interested parties, the qualities and characteristics of the newly proposed agent and its dosage forms. A wide range of information will be needed on the chemical, physical, biological and physicochemical properties of the dosage forms as well as the raw materials of the active and inactive ingredients. Many of these requirements have already been described (3). There may be apprehension that the disclosure of some of this information could imperil the confidentiality of certain manufacturing processes or trade secrets, and adequate steps would be demanded to prevent this happening. The promulgation of a standard, at or shortly after the time of registration, should have been preceded by experimental tests, in the laboratories of the Authority, to verify the robustness of the analytical methodology. In some cases more extensive confirmation by collaborative study may be warranted. The elaboration of these concepts will be presented and examples brought forward of problems that have occurred in the past, and means to prevent them in the future.
