title: Preparation and properties of a drug release membrane of mitomycin C with N-succinyl-hydroxyethyl chitosan.
abstract: A novel drug loaded membrane made of N-succinyl-hydroxyethyl chitosan and mitomycin C was used as an implant for glaucoma filtering surgery. The characteristics of the membrane, such as FTIR, equilibrium water content, swelling ratio, permeability, and drug release in vitro were determined. The L929 fibroblast inhibition of drug loaded membranes was compared to hydroxyethyl chitosan film and blank control, detecting by MTT. The biodegradability and biocompatibility were evaluated by implanting membranes into the subcutaneous tissue and muscle of rats. FTIR indicated mitomycin C was introduced. The experimental results indicated the drug loaded membrane was effective on the swelling property, permeability, and drug release in vitro. Cell culture experimental results demonstrated that the destination membrane inhibited fibroblast proliferation. In vivo, the membranes showed bioabsorption and biocompatibility. The experimental results provide a theoretical basis for the future development of the drug loaded membrane as an implant for increasing the success rate of filtering surgery.
