Kinetic Modeling to Explain the Release of Medicine from Drug Delivery Systems

Abstract

Proper medication dissolution must be ensured when developing or manufacturing a new solid dosage form. Quantitative analyses performed in dissolution or release tests become simpler when applying mathematical formulae which represent dissolution outcomes as a function of several dosage form properties. Methodologies utilized to examine the kinetics of drug release from controlled‐release formulations are reviewed. The analysis of variance was conducted using statistical, model‐independent, and ‐dependent techniques for the dissolution profile comparison and fitting, respectively. Model equations, including zero‐ and first‐order, Hixson‐Crowell, Weibull, Higuchi, Korsmeyer‐Peppas, Baker‐Lonsdale, Hopfenberg, etc., were employed to match the experimental data. Additional release parameters were taken to illustrate the drug release patterns. Using correlation factors and the Akaike information criterion (AIC), the best‐fitting model was discovered, as were the transport phenomena affecting the behavior of the recognized formulations.

“…Furthermore, depending on the value of n , the release profile of the pharmaceutical agent can be classified into the Fickian model or the non-Fickian model. 43 Diffusion controls the drug release in the Fickian model when n = 0.5. This means that the Higuchi model is suitable for this phenomenon.…”

“…The MCZ release fitted the Korsmeyer-Peppas model best. This semi-empirical model was developed to describe the release of drugs from polymeric matrices and is governed by the equation Mt = kt n , where Mt corresponds to the total amount released, k is the model constant, and n is the exponent related to the solute transport mechanism [ 42 ]. The value of n calculated for the MCZ curve was 0.3303, indicating that the drug is released from the matrix by a pseudo-Fickian diffusion mechanism.…”

“…The release of both HMSNs@Pro and HMSNs@Pro@ZnO QDs at different pH conforms to the first-order model, indicating that the release rate of Pro is directly proportional to the concentration of Pro in the nanopesticide. In addition, the Ritger–Peppas release model analyzed the release behavior of the pesticides by determining the value of the diffusion exponents n [ 48 ]. In this study, the spherical HMSNs were employed as the carrier of the pesticide, thus when n ≤ 0.43, the drug release follows the Fickian diffusion; while 0.43 < n < 1.0, the drug release demonstrates non-Fickian diffusion behavior [ 49 , 50 ].…”
