title: [Clinical study on a new acetylsalicylic acid/paracetamol preparation with gastric acid resistant coating (Safapryn), and on two various phenylbutazone dosages in patients with primary chronic polyarthritis as based on a new evaluation method].
abstract: The authors describe a simple non-crossover-blind test for the evaluation of subjective indices. A table for recording pains during the 14 days' study is described. The patient's satisfaction with the treatment and the number of days until withdrawal from the trial are recorded. The statistical procedure takes into consideration differences between the treatment groups and makes possible a valuable comparison with drugs tested in other clinical trials. The three dose schedules of antirheumatic treatment were tested on 122 patients and the results compared with those of 342 patients treated with the 6 other antirheumatic drugs (enteric-coated aspirin, paracetamol, indomethacin, flurbiprofen, mefenamic acid, and prednisolone) and those of 41 patients who received placebos. The results show that Safapryn (3,6 g aspirin + 3.0 g paracetamol daily) compared with 3.9 g enteric coated aspirin does not offer any advantage in its analgesic effect, although it gives rise to fewer side effects. Phenylbutazone (3000 mg) was almost as effective as 15 mg prednisolone daily. Between the effects of this dosage of phenylbutazone and other non-steroidal antirheumatic drugs, however, no significant difference could be detected. 50 mg phenylbutazone daily and placebo treatment could not be distinguished.
