From managing common, self-limiting GI complaints to navigating the complexities of chronic Inflammatory Bowel Disease (IBD), pharmacists play an essential role in optimizing patient outcomes. The PharmD curriculum, particularly in the Patient Care 4: Gastrointestinal and Renal Disorders course, provides a comprehensive module dedicated to this diverse topic area. This includes the management of nausea, diarrhea, constipation, and Irritable Bowel Syndrome (IBS), as well as the advanced pharmacology of aminosalicylates and biologics for Crohn’s disease and ulcerative colitis. This quiz will test your knowledge on the assessment and pharmacologic management of these prevalent GI conditions.
