ABSTRACT
Aim. Evaluation of the efficacy, safety, and tolerability of Riamilovir (trade name «Triazavirin®») in patients with mild COVID-19. Materials and methods. The randomized open-label study included 120 patients with clinical and epidemiological manifestations of coronavirus infection and its laboratory (PCR) confirmation. Results. The efficacy, safety, as well as good tolerability of Riamilovir in the treatment of new coronavirus infection (COVID-19) have been established. Conclusion. The results of the study on the efficacy, safety, and tolerability of Riamilovir allow us to recommend it as a means of etiotropic therapy of the new coronavirus infection (COVID-19). © Team of Authors, 2021.
ABSTRACT
AIM: The assessment of the effectiveness, safety and tolerance of the drug Riamilovir for emergency drug prevention in the foci of a new coronavirus infection (COVID-19). MATERIALS AND METHODS: The trial included 113 persons aged 18 years and older who had level 1 contacts with patients with a new coronavirus infection (COVID-19), who had not previously been ill, with negative PCR results for COVID-19. RESULTS: The high effectiveness, safety and good tolerance of the preventive use of the drug Riamilovir for the period of 20 days of taking a prophylactic dose of 1 capsule (250 mg) per day in the foci of COVID-19 has been established. CONCLUSION: The effectiveness and safety of the preventive use of the drug Riamilovir allow to recommend it for emergency drug prophylaxis in contact persons in the foci of a new coronavirus infection (COVID-19).
ABSTRACT
Aim. The study evaluates clinical effectiveness and safety of etiotropic antiviral medications with a direct mechanism of action (Riamiiovir, Ribavirin, Umifenovir) for the treatment of moderate SARS-CoV-2 infection in adults. Materials and methods. The study used the data from 59 health records of patients with moderate PCR-confirmed SARS-CoV-2 infection. Control group included 29 patients treated with 1250 mg Riamiiovir off-label per day for 5 days (250 mg 5 times a day), comparison group consisted of 30 patients, who received 800 mg Ribavirin and Umifenovir per day for 5 days. The effectiveness of the medications was assessed by the duration and severity of general infectious and respiratory syndromes, anosmia and ageusia, as well as the oxygen content in the blood, the timing of SARS-COV-2 virus elimination from the body according to the results of control studies of nasopharyngeal swabs using the PCR method and dynamics of blood tests results. Results. A statistically significant decrease in the duration of fever, cough, and anosmia and a more rapid elimination of the virus from the body were noted in the group of patients receiving Riamiiovir. Decreased levels of non-specific inflammatory markers in blood serum, as well as normal values of liver enzymes were observed in control group during therapy, as opposed to the comparison group. No serious adverse events were noted when using the medication. Conclusion. Nucleoside analogue medication Riamiiovir showed good effectiveness and safety profile in adult patients with moderate SARS-CoV-2 infection.
ABSTRACT
AIM: In this study we evaluated the effects of Riamilovir on SARS-CoV-2 viral shedding and on admission duration in patients with moderate COVID-19. MATERIALS AND METHODS: We have used data from 69 health records of patients with moderate severe PCR confirmed SARS-CoV-2 infection. Control group included 34 patients treated with off-label riamilovir 1250 mg per day for 5 days (250 mg 5 times a day), comparison groups 35 patients, who received ribavirin and umifenovir 800 mg a day for 5 days. The antiviral therapy was administered within 72 hours from the onset of the disease. The primary endpoints were elimination of virus in oropharyngeal and nasopharyngeal swabs on 7 day of admission and discharge from the hospital by 14 day. RESULTS: Patients assigned to riamilovir had significantly shorter time to clinical improvement as well as increased PCR negative rate by day 7. CONCLUSION: Yearly administration of riamilovir as opposed to the umifenovir and ribavirin in therapy of moderate SARS-CoV-2 infection was associated with significant shorter time to clinical improvement by 14 day of hospitalization. PCR negative rate by 7 days of hospitalization is significantly more likely in riamilovir group.
ABSTRACT
The article evaluates the results of Riamilovir use in treatment of patients with a moderate form of the disease caused by a new strain of the SARS-CoV-2 virus. It was found that the average time required to complete resolution of symptoms during treatment with the drug was 6-7 days. The first negative result of PCR analysis for the SARS-CoV-2 virus was registered on the 10-11thday of therapy;two consecutive negative PCR results for the SARS-CoV-2 virus were registered in the majority of patients by day 14-19 of treatment in 63±4.28%. The body temperature of the majority of patients (75%) returned to normal by the 4thday of treatment. CT scan showed improvement in the lungs of patients: a repeated CT scan performed on average on day 19 from the start of therapy showed no lung damage or no progression in 10±3.0% of patients following therapy. The CT scan of the lungs performed in 1-2 months after the treatment showed that the number of patients with no lung damage increased to 27±4.44%. As a result of treatment, a decrease in the C-reactive protein index was observed in patients. The tolerability level of the drug was assessed as good: no adverse events or significant deviations in laboratory parameters were detected.
