New Approaches to Etiotropic Therapy of ARVI Patients with Riamilovir

Abstract

Aim. To study the efficacy and safety of Riamilovir in patients diagnosed with acute respiratory viral infection using several dosage regimens of the drug.Material and Methods. The clinical efficacy and safety of Riamilovir were evaluated based on the results of a study, that included 150 patients in three comparative groups, 50 patients each. The research groups received etiotropic antiviral therapy with 1 capsule (250 mg) of Riamilovir 3 times per day for 5 days in the first group; in the second group, patients received Riamilovir off-label — 1 capsule (250 mg) 5 times per day for 5 days; and the third group included 50 patients who received only pathogenetic treatment.Results. As a result of the study, Riamilovir demonstrated a high safety profile regardless of the dosage regimen; no adverse events were registered. It was shown that Riamilovir use, regardless of the dosage regimen, led to a statistically significant reduction in the duration of inpatient treatment. It should be noted that the shortest periods of hospitalization were observed in patients who received the studied drug at increased daily dosages. Riamilovir was found to reduce the duration and severity of general infectious signs of the disease, while complete elimination of ARVI pathogens occurred by the 6th day of hospitalization; the shortest total duration of fever and a number of respiratory tract syndromes was registered among patients receiving Riamilovir at a daily dose of 1250 mg for 5 days.Conclusion. The etiotropic antiviral drug Riamilovir has shown clinical efficacy when used in both treatment regimens in patients with acute respiratory viral infections, as well as a good safety profile.
