"This is definitely a nice supplement to my knowledge while combining my specific expertise as a medication expert. The content presented is clinically relevant and accurate, including the most up-to-date, evidence-based recommendations. The book even includes useful notes describing current clinical debates or controversial scenarios… The authors provide "rules of thumb" that are used in clinical practice and may be difficult to find in medical literature." -©Doody’s Review Service, 2022, Marc Crane, PharmD (Penn Medicine) Doody's Score: 4 Stars!
