This is a concise reference, including summary tables for drug dosing in obese patients. This resource will provide practitioners with information regarding pharmacokinetic parameters that impact obese patients to aid them with dosing medications. It addresses specific therapeutic areas, primarily for acute care settings with some-overlap for drugs used in ambulatory settings.
