Treatment with drugs is fundamental to modern therapy of psychiatric disorders. Since the publication of the first edition of this book, significant advances have been made in psychopharmacology. In this second edition the author has provided a thoroughly revised volume, which includes a list of key references and a glossary of terms, abbreviations and synonyms. New material has been added, including chapters on molecular genetics and functional neuroanatomy, as well as two intriguing chapters which give a flavour of the development of psychopharmacology in the 21st century.
