Nonlinear regression fitting was performed on the dissolution results of INM at various temperatures, using eqn (1). The concentration of INM released immediately after dissolution (C₀), the saturated concentration of INM (C_S), the product of the dissolution rate constant and the effective surface area of powder particles (kS), and the sum of squared residuals (SS) were listed.
