Based on the WHOs Anatomical Therapeutical Chemical drug classification system, virtually all marketed therapeutics are covered here in 46 topical and systematic articles. Each carefully selected section contains a general introduction to the therapeutic class, current developments and challenges, followed by a systematic listing of all important products. For each therapeutic, up-to-date information on compound structure, mechanism, pharmacology, clinical use, time on market, and production methods is provided, complete with references to the scientific and patent literature. With all articles either rewritten or completely updated to include marketed drugs up to 2021, this unique reference provides reliable data on more than 2,000 products, making it an indispensable guide for every professional in the pharmaceutical and medical sector.
