mobiflex and aceclofenac

To compare in a 3 month, multicenter, double blind, parallel study the efficacy and safety of a nonsteroidal antiinflammatory drug, aceclofenac, 100 mg bid orally, with that of tenoxicam, 20 mg orally at bedtime, in the treatment of adult patients with active ankylosing spondylitis (AS).. A total of 273 patients (135 in the aceclofenac group and 138 in the tenoxicam group) entered the study. Eight efficacy variables were assessed: morning stiffness, visual analog pain scale, control of additional paracetamol, modified Schöber's test, C7 line-iliac crest distance, lateral flexion of the spine, thoracic expansion, and occiput-wall distance.. Seven of the 8 variables improved significantly in both groups, with no differences between the 2 groups in any variable at the end of the study. Six percent of patients taking aceclofenac and 5% of patients taking tenoxicam withdrew because of unsatisfactory therapeutic action. Forty-two adverse events possibly or probably related to treatment were observed in the aceclofenac group and 37 in the tenoxicam group. However, only 2.2% of patients in the aceclofenac group and 1.4% in the tenoxicam group withdrew for this reason.. Aceclofenac and tenoxicam are similar in terms of safety and effectiveness; and aceclofenac, 100 mg orally twice daily, is a safe, effective, and convenient treatment for active AS.

To compare the efficacy and safety of aceclofenac (AC) and tenoxicam (TX) in the treatment of rheumatoid arthritis (RA), a multicentric parallel, randomized, double-blind trial of three months duration was performed in 292 patients: 145 were randomized to the AC treatment group and 147 to the TX treatment group. The trial was completed by 237 (81.1%) patients. Both treatment groups showed amelioration of clinical parameters monitored at 15 days, and this improvement continued until the end of the trial, no statistically significant differences being observed between AC and TX. Twenty-four patients (8.2%, 12 AC and 12 TX) did not complete the trial because of inefficacy, and 15 because of side effects (5.1%, 6 AC and 9 TX), in 7 of them due to gastrointestinal intolerance (2,4%, 1 AC, 6 TX, p = 0.052). These data demonstrate that AC shows similar efficacy to TX in the treatment of rheumatoid arthritis and better safety profile than TX, mainly regarding gastrointestinal tolerability.

To study the effects of the non-steroidal anti-inflammatory drugs (NSAIDs) aceclofenac, piroxicam, tenoxicam and indomethacin on cytokine, matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs) and prostaglandin E2 (PGE2) production, by interface membranes (IFT), obtained at revision surgery for aseptic loosening of total joint arthroplasty. Involvement of these soluble factors is well documented and probably, a pharmaceutically induced inhibition of them might retard loosening.. IFTs from 10 patients with a loose hip or knee endoprosthesis were collected. The possibility of septic loosening was thoroughly excluded by histopathologic and microbiologic evaluation. IFTs were cultured in the absence or presence of the tested drugs and the levels of the soluble mediators were determined, using electrophoretic and enzyme-linked immunosorbent assay techniques. Paracetamol was used as neutral drug.. All NSAIDs exhibited a pronounced inhibitory effect upon the production of interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha). This specific effect on IL-6 is reported in the literature for the first time. The majority of NSAIDs also induced the production of IL-1beta in an adequate portion of samples. These drugs did not have a clear effect on MMP synthesis, but they had a stimulatory tendency on TIMP-1 production. Paracetamol, significantly decreased the synthesis of TNF-alpha and that of the gelatinases.. Our in vitro results are encouraging, since it appears that the action of NSAIDs, globally considered, may be beneficial upon the loosening process. The inhibitory effect of paracetamol upon TNF-alpha and gelatinases is intriguing. Our data, if supported by similar observations, probably justify performance of long-term clinical trials.

A polarographic study about how three anti-inflammatories, such as Aceclofenac, Tenoxicam and Droxicam behave, using tast polarography (TP) and differential pulse polarography (DPP) was carried out. These studies were always carried out in a media formed by Methanol-Britton-Robinson aqueous buffer (0.1M) (4:96 (v/v)) due to the low solubility of these drugs in water. A strong influence of pH on analytical signals was observed, showing that the optimal pH values were between 4 and 5. Using DPP in the optimal experimental conditions, a detection limit of 10 ppb for Tenoxicam and Droxicam and 52 ppb for Aceclofenac was reached. The DPP proposed method was successfully applied to the determination of the active compounds in commercial drugs.
