Development and Characterization of Sodium Alginate/Poly(vinyl alcohol) Blend Scaffold with Ciprofloxacin Loaded in Controlled Drug Delivery System

drug-controlled release studies showed a slower and more continuous release for the SA/PVA in comparison with plain SA and PVA and the drug-delivery cumulative release was proportional to the amount and the interlayer distance of SA/PVA blend scaffolds. A sustained drug release pattern was observed with a non fickian diffusion mechanism.
