A Review of Stress Ulcer ProphylaxisSchool of Pharmacy, University of Colorado Health Sciences Center, 4200 East Ninth Avenue (C238), Denver, CO 80262, rob.maclaren{at}uchsc.edu Stress-related mucosal damage (SRMD) is an erosive process of the gastroduodenum that occurs frequently in critically ill patients. Symptomatic lesions may range from overt bleeding (by hematemesis, melena, bloody or coffee ground aspirates, or hematochezia) to clinically significant hemorrhage (hypotension, tachycardia, or acute anemia requiring transfusion). SRMD is caused by mucosal ischemia that produces an imbalance between injurious factors and the protective mechanisms. Common patient risk factors include mechanical ventilation, coagulopathy, shock, hepatic dysfunction, renal dysfunction, thermal injury, trauma, kidney or liver transplant, head injury or spinal cord injury, recent gastrointestinal hemorrhage, and pharmacologic interventions. Stress ulcer prophylaxis may be provided by administering one of the following pharmacologic agents: an antacid, a histamine2 receptor antagonist, sucralfate, or a proton pump inhibitor. All agents possess equal efficacies but differ in their mechanisms of action, adverse event profile, drug interactions, monitoring requirements, costs, and personnel requirements for preparation and administration. Implementation of institution-specific protocols for stress ulcer prophylaxis provides cost minimization by maximizing appropriate drug usage.
