This book provides practical information on how to use various psychotropic drugs in clinical practice, focusing on their mechanisms of action on receptors and enzymes in the brain. Divided into 11 chapters, it covers all main drug classes, with a dedicated chapter each on special populations and upcoming drugs. All the drugs discussed are presented in the same design format in order to facilitate rapid access to information. Specifically, each drug is individually divided into sections – its history and introduction, classification, pharmacological action, doses, drug interactions, indications, side effects and special populations. Only the essential facts about each drug have been included, so as to make the content concise and to avoid dilution of important information. To aid with review, key points are summarized at the end of each chapter.
