Evaluation of quality of life following treatment with etoricoxib in patients with arthritis or low-back pain: an open label, uncontrolled pilot study in Mexico.

An open-label study was undertaken at multiple centers in Mexico to assess the impact of treatment with etoricoxib - a selective cyclo-oxygenase-2 (COX-2) inhibitor - on quality of life (QoL) and pain relief among patients with osteoarthritis (OA), rheumatoid arthritis (RA) or chronic low-back pain (CLBP). The study involved 191 adult patients (aged > 18 years old) who had used non-selective non-steroidal antiinflammatory drugs (NSAIDs) for the treatment of OA, RA or CLBP during the month prior to study enrolment. After discontinuation of prior therapy, patients were treated with etoricoxib 60 mg for OA and CLBP,or 90 mg for RA once daily for 2 weeks.
