Pharmacogenomics: Foundations, Competencies, and the Pharmacists’ Patient Care Process, Second Edition provides a basic and clinical foundation for the application of drug-gene interactions in clinical therapeutics. As the field of PGx advances and changes rapidly, there is a need for a regularly updated, pharmacy-focused resource that can be a reference for practicing pharmacists and student pharmacists in the context of the Pharmacists’ Patient Care Process (PPCP). Specific information is presented through “PGx Pearls.” Each of the 20 cases are presented in the context of the PPCP, with “Competency Connections” related to updated pharmacists’ competencies in genetics and genomics. Each chapter provides content and objective-related questions with the answers provided.
