IntroductionWe compared, by a meta-analytic process, the antipyretic and symptomatic activity, and the safety profile of morniflumate (ATC code: M01AX22) with those of other commonly used non-steroidal anti-inflammatory drugs (NSAIDs) in acute ear, nose and throat (ENT) diseases.Evidence AcquisitionOur search strategy was performed in various database, included Google Scholar, PubMed and Embase, the key word was "morniflumate". Interventional studies in adults with ENT or lower airway inflammatory diseases were compared in a meta-analysis for the number of symptom-free and fever-free patients at day 3 of therapy, and of drug interruptions due to adverse events (AEs). For symptoms, we included only studies on ENT inflammatory diseases; for fever and AEs, we also considered studies on lower airway inflammatory diseases. Of 33 studies retrieved, 8 (24.2%) met the inclusion criteria and compared morniflumate to placebo, nimesulide, paracetamol and other NSAIDs.Evidence SynthesisOn day 3, the number of symptom-free patients was significantly higher with morniflumate vs placebo and nimesulide (+20% and +30%, respectively) and similar to the other comparators. The number of fever-free patients significantly increased (up to 70%) with morniflumate vs all comparators except paracetamol (similar). No difference was found in the number of AE-related interruptions.Conclusionsmorniflumate showed good antipyretic and symptomatic activity and a short-term safety profile at least comparable to that of other NSAIDs.
