Tenidap in patients with rheumatoid arthritis. A 4-week, placebo-controlled study.

The present double-blind, placebo-controlled study was conducted to compare the safety and efficacy of tenidap in patients with rheumatoid arthritis (RA). Patients with flare of active RA following NSAID withdrawal were randomized to receive either placebo (n = 67) or tenidap (n = 131; 40-200 mg/day). The mean changes from baseline in efficacy and biochemical variables were compared between treatment groups at endpoint (4 weeks). The improvements in four of the five primary efficacy variables were significantly greater in the tenidap group compared with the placebo group (p < 0.01). Tenidap was also associated with an 18% reduction in erythrocyte sedimentation rate (ESR) and a marked, 51%, reduction in serum C-reactive protein (CRP) level, both of which were significantly greater than the changes in the placebo group (p < 0.05). The percentage of patients who discontinued because of side effects was the same in both groups (3%). In conclusion, tenidap 40-200 mg/day was effective and well tolerated in the treatment of patients with RA for 4 weeks.

A controlled study comparing the effects of nabumetone, ibuprofen, and ibuprofen plus misoprostol on the upper gastrointestinal tract mucosa.

BACKGROUND: This study was developed to compare the incidence of endoscopically diagnosed ulcers in elderly patients taking nabumetone, ibuprofen, or concomitant ibuprofen/misoprostol. Further research is indicated to better establish the clinical relevance of these endoscopy findings. METHODS: We conducted a prospective, multicenter, randomized, endoscopist-blinded, 12-week study involving 171 patients with osteoarthritis aged 60 years and older. Patients were randomized to receive nabumetone, 1000 mg (n = 58); ibuprofen, 600 mg four times daily (n = 53); or ibuprofen, 600 mg four times daily, administered concomitantly with misoprostol, 200 micrograms four times daily (n = 60). Endoscopy was performed at baseline and at weeks 2, 6, and 12. Endoscopy results were scored on a scale of 1 to 9. Significant ulcers were defined as breaks in the mucosa greater than 5 mm with appreciable depth. RESULTS: Of the 171 randomized patients, 148 completed the study. There was no significant difference in the incidence of significant ulcers between the nabumetone group and the ibuprofen/misoprostol group (one vs zero). There were significantly fewer significant ulcers in the nabumetone and ibuprofen/misoprostol groups than in the ibuprofen monotherapy group (one and zero vs eight; P < .01). There also was a significant difference in the time to ulcer development, with a greater risk of developing an ulcer sooner with ibuprofen treatment (P < .01) than either nabumetone or ibuprofen/misoprostol treatment. The severity of osteoarthritis, based on physicians' assessments, improved in 64% of patients in the nabumetone group, 55% of those in the ibuprofen group, and 63% of those in the ibuprofen/misoprostol group. CONCLUSIONS: Nabumetone is equivalent in ulcerogenicity to concomitant ibuprofen/misoprostol and is significantly less ulcerogenic than ibuprofen alone.

Ibuprofen or aspirin in rheumatoid arthritis therapy.

Ibuprofen is a nonsteroidal drug with analgesic, antipyretic, and anti-inflammatory properties that was recently introduced for use in antiarthritis therapy in the United States. In a year-long double-blind multiclinic trial in 885 patients with rheumatoid arthritis, ibuprofen was at least as satisfactory as aspirin, considering both efficacy and tolerance. In the majority of patients, daily doses ranged from 800 to 1,600 mg of ibuprofen and 3 to 6 gm of aspirin. The drugs did not differ greatly in providing relief from arthritis symptoms, but ibuprofen was definitely better tolerated, especially in regard to gastrointestinal complaints. Seven percent of the ibuprofen group dropped out of the study because of adverse reactions, as compared with 16% of the aspirin group; 17% of the ibuprofen group and 31% of the aspirin group had gastrointestinal symptoms.
