Clinical study of a new anti-inflammatory and analgesic compound, benorylate, in rheumatic disorders.
Benorylate is obtained by esterification of acetylsalicylic acid and N-acetyl p-aminophenol (4-acetamidophenyl 2-acetoxybenzoate). Experimentally, this new product has been shown to be a good analgesic and anti-inflammatory agent. A clinical trial was carried out in order to study the efficacy, side effects and tolerance of this new product. In a group of 49 hospitalised patients aged from 20 to 70 years who were treated with this new product, 15 had ankylosing spondylitis, 11 had chronic progressive rheumatoid arthritis, 4 had Reiter's syndrome, 4 had psoriatic arthropathy, 8 had osteoarthrosis of the hip and 7 had various forms of rheumatism. The drug was administered orally in suspension form, initially three times per day, then twice, the total daily doses being 15 ml (6 g) or 20 ml (8 g). Treatment was regarded as effective in 62% of the cases, and of these 62%, 46% good and very good results were obtained. In 88% of the patients, tolerance was satisfactory and of these, it was excellent in 80%. Only in 2 cases did treatment have to be discontinued on account of side effects. From the biological point of view, uricaemia was significantly reduced in 7 patients, and in 6 patients uricuria increased. With regard to the level of salicylate in the blood assays showed that it is the same for 6 g benorylate and for 4 g aspirin. Benorylate has been shown to be an effective treatment for both inflammatory and degenerative rheumatic disorders. The results of its use can be compared with those obtained by acetylsalicylic acid, but is better tolerated. In addition, in chronic disorders it is better to have to take the product only twice per day.
