RESUMO
When anti-inflammatory/analgesic agents are not well tolerated, patients with arthritis may be prescribed a cyclooxygenase-2 (COX-2) inhibitor. Since these patients often require daily treatment and COX-2 inhibitors are more expensive than nonselective nonsteroidal anti-inflammatory agents, it is important to assess their patterns of use. In this retrospective study, rofecoxib and celecoxib were compared, in a managed care population with arthritis, in terms of average daily medication consumption and cost. Celecoxib was found to be significantly more costly than rofecoxib, and certain factors, such as the treating physician's specialty, correlated with prescribing patterns. Given the high prevalence of arthritic conditions, these results suggest that the selection of a COX-2 inhibitor may substantially affect health care costs.
