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 10-11 day 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 4 day 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.
