Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly consumed drugs worldwide for the relief of pain and arthritis. However, the use of NSAIDs increases the risk of ulcer bleeding by 4-fold. Current evidence indicates that combination of conventional NSAIDs and a proton pump inhibitor (PPI) reduces the risk of ulcer complications. The alternative strategy is to replace conventional, non-selective NSAIDs with NSAIDs selective for cyclooxygenase-2 (COX-2 inhibitors). Recently, there are concerns about the cardiovascular safety of COX-2 inhibitors and conventional NSAIDs. Because of such concern, patients requiring anti-inflammatory analgesics who have cardiovascular risk factors (e.g. smoking, hypertension, hyperlipidemia, diabetes) should receive prophylactic low-dose aspirin. However, concomitant low-dose aspirin negates the gastric sparing effect of COX-2 inhibitors and augments the gastric toxicity of nonselective NSAIDs. Thus, gastroprotective agents such as PPIs should be co-prescribed to patients with high ulcer risk who are taking aspirin plus a COX-2 inhibitor or a nonselective NSAID.
