Drugs play an important role throughout the world. In industrialized countries where a formal approval process governs the introduction of new medicinal agents, thousands of chemicals are in use as drugs. This book provides a detailed picture of this marketplace. Grouped by their medicinal use and biological activity, 8,000 drugs in common use around the world are described. For each, the chemical name and a list of trade names and synonyms are provided; the CAS Registry Number and the European Inventory of Existing Chemical Substances (EINECS) Number are given; the physical properties of each compound are described, and the known biological activity and indicated applications are presented. Indexes, including a master index of name and synonyms, are appended. This compendium should be valuable to physicians, research chemists, biologists and the lay public who, with a single synonym for a drug, will be able to quickly find a thumbnail sketch of the essential information concerning the agent.
