Respiratory infections caused by COVID-19 are a global health problem, and it is important to find additional candidates that can reduce inflammation and enhance the efficacy of treatment. This study found that muco-inhalable delivery system (MIDS) loaded with silymarin can alleviate inflammation and exhibit antiviral activity against COVID-19.
Respiratory infected by COVID-19 represents a major global health problem at moment even after recovery from virus corona. Since, the lung lesions for infected patients are still sufferings from acute respiratory distress syndrome including alveolar septal edema, pneumonia, hyperplasia, and hyaline membranes Therefore, there is an urgent need to identify additional candidates having ability to overcome inflammatory process and can enhance efficacy in the treatment of COVID-19. The polypenolic extracts were integrated into moeties of bovine serum albumin (BSA) and then were coated by chitosan as a mucoadhesion polymer. The results of interleukin-6, and c-reactive protein showed significant reduction in group treated by Encap. SIL + CUR (64 +/- 0.8 Pg/mu L 6 +/- 0.5 mu g/mu L) compared to group treated by Cham. + CUR (102 +/- 0.8 Pg/mu L & 7 +/- 0.5 mu g/mu L) respectively and free capsules (with no any drug inside) (148 +/- 0.6 Pg/mu L & 10 +/- 0.6 mu g/mu L) respectively. Histopathology profile was improved completely. Additionally, encapsulating silymarin showed anti-viral activity in vitro COVID-19 experiment. It can be summarized that muco-inhalable delivery system (MIDS) loaded by silymarin can be used to overcome inflammation induced by oleic acid and to overcome COVID-19.
