Higuchi formula
WebMar 2, 1998 · Despite its simple form, Higuchi's equation reasonably represents the rate of drug release for most drug concentrations, although it strictly predicts the exact result … WebNumerical fits indicate that the Higuchi square root of time model was the most appropriate one for describing the release profile of theophylline from hydrophobic matrices. The release mechanism was also explored and explained with biexponential equation. Application of this model indicates that Fickian or case I kinetics is the predominant ...
