Kinetic Model | Equation | Description | Plot Graph | Ref. |

Zero order | $C={C}_{o}+{K}_{o}t$ | Where, C | Cumulative % drug release vs. time | Okano et al., 1987 Yin et al., 2009 Park, 2014 |

First order | $\mathrm{log}{C}_{t}=\frac{\left(\mathrm{log}{C}_{o}-{k}_{1}t\right)}{2.303}$ | Where, C | Log % of drug remaining vs. time and the slope of the plot gives the first order rate constant | Hallam et al., 1983 Shah and Rajput, 2017 Mucientes and Peña, 2009 |

Higuchi | $Q={K}_{H}{t}^{1/2}$ | K | Cumulative % drug release vs. square root of time | Gouda et al., 2017 Higuchi, 1963 Siepmann and Peppas, 2011 |
