In vitro mean the cumulative release of SA profiles under different conditions of pH and GSH (glutathione). SA release from nanoformulations under three levels of pH (7.4, 6.8, and 5.5) (A). SA release from nanoformulations under three levels of pH (7.4, 6.8, and 5.5) combined with GSH (10 mM) (B). SA release from nanoformulations under three levels of pH (7.4, 6.8, and 5.5) combined with GSH (20 mM) (C). The data presented for release profiles are mean ± SD
