RESUMO
The goal of this study was to obtain data for prescription habits, tolerability for patients at high risk, and clinical effectiveness of meloxicam administered at 7.5 mg and 15 mg for various rheumatic diseases under real world prescribing conditions. This was a 3-month large-scale prospective observational cohort study in 4000 medical practices throughout Germany shortly after the introduction of meloxicam. To be eligible, patients had to have a diagnosis of acute or chronic active rheumatic disease for which nonsteroidal antiinflammatory drug (NSAID) therapy was required according to the prescribing information. In this study, 13,307 patients receiving meloxicam prescriptions (7.5 mg in 65% and 15 mg in 33%) were observed. The diagnoses of these patients included osteoarthritis (61%), rheumatoid arthritis (24%), ankylosing spondylitis (1.6%), and other rheumatic conditions (28%). A substantial proportion of high risk patients were enrolled: 12% with a previous history of a perforation, ulceration, and bleeding (PUB), 24% with at least one concomitant cardiovascular disorder, and 26% receiving concomitant antihypertensive medication. Many of the patients (58%) had received NSAIDs before meloxicam, including patients with insufficient prior treatment effectiveness (43%) and those with NSAID-related adverse drug reactions (21%). In 85% and 94% of the patients, respectively, effectiveness and tolerability were rated as good or very good. Quality of life and daily functions improved in 64% to 84% of the patients. Only 0.8% of the patients reported gastrointestinal (GI) adverse drug reactions. Four uncomplicated cases of gastric ulceration, one serious perforated gastric ulcer, and one serious ileus complication were reported after incorrect use or overdosing of meloxicam. Treatment with the selective cyclooxygenase-2 (COX-2) inhibitor meloxicam in doses of 7.5 mg and 15 mg resulted in meaningful treatment responses under real life conditions, despite inclusion of a substantial number of patients with insufficient effectiveness of previous use of non-COX-2 selective NSAIDs. All major GI toxicity (PUB) observed was owing to the fact that prescribing conditions were not respected appropriately. Despite a selection of high risk patients overall, GI, cardiovascular, and renal tolerability was favorable.
