drugs in regular use today, their biochemical and cellular mechanisms of action, pharmaco­ kinetics, dosage regimens, therapeutic responses, adverse reactions, and drug interactions and tolerance. In addition, certain therapeutic principles that are still in an experimental phase are described, for example, immunotoxins, thymic hormones, and interleukins. The book presents comprehensive information on various autoimmune diseases, the etiopathogenetic immune mechanisms where these are known, and the current possibilities for immunopharmacological intervention. The specific disease section also covers rare situations, fluctuations in disease patterns, and subgroups of patients and immunophar­ macological treatment in these situations. Altogether, the book represents a practical textbook for clinicians and advanced students who want to be updated on therapeutic principles with regard to autoimmune diseases and transplantation.
