In vitro dexamethasone release studies. Graph showing dexamethasone release under in vitro conditions (N = 4). (Black triangle) dexamethasone release from ethanolic solution. Dexamethasone was completely released in 4 h (black square) dexamethasone release from Vit E TPGS alone. Dexamethasone release was sustained up to ~22 h and (black diamond) dexamethasone release from blend of Vit E TPGS and Oc-40 (4.5:2.0) mixture for more than 100 h
