Its successful approach emphasies the mechanisms by which drugs act and relates these to the overall pharmacological effects and clinical uses. It sets out for the reader a clear route from a molecular understanding of receptors and drug actions, to the therapeutic uses of the most important groups of drugs. For the Fifth Edition the text has been completely updated, incorporating significant new information published in the last few years, while obsolete material has been removed. New agents are fully discussed as well as extensions of basic knowledge which presage further drug development. Book jacket.Rang, H.
