WebMay 25, 2016 · The mechanism of the drug release was determined by fitting in vitro release data to various release kinetic models such as the zero order, first order, Higuchi, Hixson Crowell and Korsemeyer–Peppas model and finding R 2 values for the release profile corresponding to each model. The results confirm that the release rate of the drug from … WebFeb 1, 2024 · The Higuchi model implies that the amount of drug liberated form the dosage form is a function of the square root of time. The Hixson–Crowell model describes a …

WebDec 1, 2016 · Higuchi model was simplified to f t = K H t where, KH is the Higuchi dissolution constant. Hence, Higuchi described the drug release as a diffusion process based on Fick’s law i.e. square root time dependent ( Fig. 6) ( Siepmann and Peppas, 2012 ).

WebFeb 14, 2024 · The release kinetics of TMP@COF is also studied using zero-order, first-order, Higuchi, and Korsmeyer-Peppas models. Our results indicate that the diffusion kinetics of the COF nanodrug carrier is consistent with the Higuchi model, thus evidencing the possibility of stable TMP diffusion from the porous material. candle stuff ltd
