Samenvatting
Retaining the successful previous editions′ programmed instructional format, this book improves and updates an authoritative textbook to keep pace with compounding trends and calculations addressing real–world calculations pharmacists perform and allowing students to learn at their own pace through examples.
Connects well with the current emphasis on self–paced and active learning in pharmacy schools
Adds a new chapter dedicated to practical calculations used in contemporary compounding, new appendices, and solutions and answers for all problems
Maintains value for teaching pharmacy students the principles while also serving as a reference for review by students in preparation for licensure exams
Rearranges chapters and rewrites topics of the previous edition, making its content ideal to be used as the primary textbook in a typical dosage calculations course for any health care professional
Reviews of the prior edition: "...a well–structured approach to the topic..." (Drug Development and Industrial Pharmacy) and "...a perfectly organized manual that serves as a expert guide..." (Electric Review)
