Study of the medicine MestaMidin®-nos virucidal activity of against influenza and ARD pathogens

Introduction. Respiratory diseases have always been a serious threat to public health, but in 2020 the situation deteriorated significantly due to the rapid development of the coronavirus infection COVID-19. Due to the lack of available means of ethiotropic therapy and the still insufficient coverage of the general population with vaccination, disinfectants, as well as topical preparations that prevent the penetration of the virus into the body, play an important role in preventing the spread of infection.

Aim of the study. This work is devoted to the study of the virucidal activity of the medicine Mestamidin-nos against respiratory viruses, namely influenza A and B viruses, parainfluenza, respiratory syncytial, adenovirus and seasonal coronavirus.

Materials and methods. This study was carried out by the suspension method according to MU 3.5.2431-08 “Study and assessment of the virucidal activity of disinfectants”.

Results. It was shown that for all studied viruses the use of the compound for 60 minutes led to a complete (up to 0 lgTID50) or sufficient (4 lgTID50) decrease in the viral titer. In the case of a study of a compound with a protein load (imitating strong organic pollution), the effectiveness of the compound was significantly reduced against influenza A viruses, one of the strains of influenza B virus, adenovirus and seasonal coronavirus.

Conclusion. Based on the results of the study, it can be concluded that the effective inhibition of pathogens of influenza and acute respiratory infections using the compound MesaMidin®-nos in the absence of strong organic pollution.
