This third edition of 'Essentials of Psychopharmacology' is, like its predecessors, based upon the premier book in the field, the exhaustive 'Textbook of Psychopharmacology' (now in its 4th edition). The Essentials format is designed to provide a thorough update of the evidence base in terms of both specific medications and psychopharmacological treatment, critical information for psychiatry residents, primary care physicians, and other health care professionals involved in clinical care. A substantive revision with up-to-the-minute references, the book features new chapters on medications introduced since the last edition, expanded coverage of other recent drugs, and a new chapter on cognitive enhancers, a topic which has received a great deal of attention in both the medical literature and popular press as the U.S. population ages. The book is divided into two parts, Classes of Pyschiatric Treatments, which is broken down by drug class (antidepressants, antipsychotics, et al.) and Psychopharmacological Treatment, which provides specific treatment recommendations for the full range of major psychiatric disorders. Though the latter has been streamlined in this new edition, coverage of critical issues such as indications, interactions, side-effects, and other prescribing factors remains comprehensive, and clinicians can rely absolutely upon its accuracy, efficacy, and usefulness. A hands-on reference, 'Essentials of Psychopharmacology' is, hands down, the best of its class.
