Achieving Zero-Order Release Kinetics Using Multi-Step

In our study, the relative importance of swelling and erosion in the controlled release of felodipine is quantified through the application of a statistical model and SR-μCT. The solubility of felodipine in the dissolution medium is 970 μg/mL (0.097%, w/v), which is relatively close to the low level solubility (0.02%, w/v) in Bettini et al.’s study.CONTROLLED RELEASE DRUG DELIVERY DESIGN AND MANUFACTURE.
