Amtolmetin: A Reappraisal of NSAID with Gastroprotection.

Aim. To assess the gastrosparing effect of amtolmetin guacyl (AMG) against other nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with osteo-/rheumatoid arthritis. Methods. A literature search was done in the electronic databases (PubMed, Google Scholar, Embase, and Scopus) with key words "amtolmetin guacyl", "amtolmetin", and "arthritis"; filters were applied to obtain publications between 01-Jan-1985 and 01-Oct-2015, which were "clinical trials" in osteo-/rheumatoid arthritis patients and in "English language." Studies were assessed using the Jadad criteria and trials with score ≥ 3 were included in the analysis to compare the safety and efficacy of AMG against other NSAIDs. Results. Search yielded 19 publications of which 3 were included for analysis. Baseline characteristics of patients were comparable between the AMG group and other NSAIDs (diclofenac, celecoxib, and piroxicam) groups in all trials. Efficacy of AMG was similar to the other NSAIDs compared in the trials. The number of adverse events (AEs) reported was similar between both the groups; however, severe AEs reported were significantly lower in the AMG group. Of note was the significant lower number of duodenal ulcers after treatment in the AMG group. Conclusions. AMG has efficacy similar to other NSAIDs and a safer gastrointestinal AE profile when compared to the other NSAIDs.
