... Studies: Drug release profiles of Ao, A1, A2, A3, CH blends in acid and neutral media are shown in Figure 3 and 4. It was observed that the release characteristics of chitosan-starch film depend on both composition of film and pH of release medium (Virpal, 2014). The release behaviors of hydroxyurea were shown similar initial release behavior. ...

... drug release rate was maximum for first hour and it may attribute to present some of the drug on the outer surface of the films and it was released when the films were immersed in the fluid media ( Raizaday et al., 2015). Figure 3 shows that the quantity of drug released at pH 7.4 was decreased with increasing chitosan amount in the blend. This may be due to the formation of a dense matrix as a result of increasing chitosan in the blends which led to reduce the swelling of the films ( Kumari and Kundu, 2008). ...
