Description
This fourth edition of How Drugs Work equips readers with a set of clear concepts for matching the pharmacology to the diagnosis, and has been completely revised and updated to reflect the latest knowledge and terminology. Rather than providing overwhelmingly comprehensive information, it condenses the aspects of pharmacology directly relevant to everyday practice into a concise, accessible volume, including material on the half life of drugs, patient non-compliance and severe chronic inflammation.
