Quantifying the impact of NSAID-associated adverse events.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used among patients experiencing many different types of pain, including inflammatory, acute pain (eg, injury, low back pain, headache, postoperative pain), and chronic pain (eg, rheumatoid arthritis, osteoarthritis). However, both traditional NSAIDs and second-generation NSAIDs (cyclooxygenase-2 inhibitors) can lead to very expensive and serious adverse events. Gastrointestinal, cardiovascular, and renal complications associated with NSAIDs have been shown to be dose-dependent. In 2005, to help minimize these risks, the US Food and Drug Administration issued a public health advisory stating that "NSAIDs should be administered at the lowest effective dose for the shortest duration consistent with individual patient treatment goals." This article reviews the undue clinical and economic burden associated with NSAID-related serious adverse events.
