The present volume deals with drugs which play an important role in the therapy of schizophrenia. It describes the introduction of the first antipsychotics on the market and the importance of clozapine, a prototype for atypical antipsychotics, for further investigation of other potentially atypical antipsychotics, which may have an important impact on the therapy and especially the well being of schizophrenic patients, and their introduction in clinical practice. The book is written by experts in the field of schizophrenia both from a clinical and preclinical point of view. It is of interest to practising psychiatrists, to neuroscientists working in the pharmaceutical industry and also to medical students.
