ABSTRACT
Nowadays, large part of the population in Hungary is affected by the dry eye disease or symptom. Most of these magistral pharmaceuticals (FoNo VI) compared to the industrial products have disadvantages. They are not compatible with contact lenses, because of the preservatives and after opening they can be used only for seven days. In our experiments we used sodium-perborate as preservative, which could be a solution for the problems mentioned above. Our results indicate that the sodium-perborate sterilized the solution and resists against microbiological contamination. Its preservative effect maintained for more than four weeks. Our further purpose is to develop a new pharmacy drug preparation method to find an effective solution for the microbiological stability-related problems of artificial tears.
