AimTo evaluate the efficacy and safety of Polyoxidonium® in patients with inflammatory and infectious upper respiratory diseases in real clinical practice.Materials And MethodsThis retrospective multicenter study included data from adults and children over 6 months old with inflammatory and infectious upper respiratory diseases (n=16 365). The exploratory endpoints included: the proportion of patients with complete relief of symptoms, demographic characteristics of patients, the frequency of prescriptions of Polyoxidonium® by disease groups, determination of the groups of concomitant drugs, most commonly prescribed treatment regimen, frequency of prescribing different Polyoxidonium® dosage forms, duration of the most common specific symptoms of acute respiratory infections during therapy, the incidence of treatment-related adverse events.ResultsAfter treatment completion, the proportion of patients with complete relief of symptoms was 40%, with positive dynamics - 99.77%. Polyoxidonium® in combination therapy was also effective in the treatment of COVID-19 and Post-COVID-19 syndrome. The median patient age was 28 years. Polyoxidonium® was most frequently prescribed for the treatment of inflammatory and infectious upper respiratory diseases in combination with antibiotics or symptomatic drugs in dosage form solution. The primary routes of administration were intranasal and sublingual. The resolution of infection symptoms occurred predominantly within the first 5 days after the initiation of therapy. The therapy appeared to be equally effective across all age groups. No Polyoxidonium®-related adverse events occurred.ConclusionTreatment with Polyoxidonium® contributes to achieving favorable outcomes in patients with inflammatory and infectious upper respiratory diseases. The study drug has a high safety profile.
