Surface modification of poly(methyl methacrylate)-sulphadiazine complexes as self photostabilizer against Ultraviolet (UV) Irradiation

Materials research innovations (Print), 2023
Surface functionalization of PMMA by Aminolysis reaction was utilised along with the addition of inorganic photo stabilisers (Zn(II), Ni(II), Cu(II) and Co(II)) to enhance the photostability of PMMA under exposure to UV light.

Photostabilization strategies of photosensitive drugs

International Journal of Pharmaceutics, 2018
Several active compounds are sensitive to light, especially to the ultraviolet radiation (UV-R) leading to their degradation or modification, with lost or decrease of their biological activity. The aim of this study was to perform a systematic review regarding photostabilization strategies used on health products and perform a critical appraisal of ...
