Is it possible to give a cold child Groprinosin together with Pneumo 3 Biotic and Immunotrophin?

There is no information available to suggest that Groprinosin interacts with the ingredients in Pneumo 3 Biotic and Immunotrophin. However, according to available studies, inosine (the active ingredient in Groprinosin) does not shorten the duration of the infection or relieve its symptoms. So I do not see the legitimacy of its use in a cold child. I attach additional materials: https://www.gdziepolek.pl/artykuly/jak-wzmocnic-odpornosc-u-dziecka-przed-pojsciem-do-szkoly
