Objective: Colorectal cancer is one of the most commonly diagnosed cancer and also most common gastrointestinal malignancy with high prevalence rate in the younger population. Usually, cancer cells are surrounded by a fibrin coat which is resistant to fibrinolytic degradation. This fibrin coat is act as self-protective against natural killing mechanism. The main objective was to prepare papain-loaded solid lipid nanoparticles (P-SLN) by melt dispersion-ultrasonication method and investigated the cytotoxic efficacy against colorectal adenocarcinoma (human colorectal adenocarcinoma [HCT 15]) cells.Methods: Optimized polymer ratio was characterized by differential scanning calorimetry, Fourier-transform infrared, X-ray diffraction, scanning electron microscopy, entrapment efficiency, particle size and zeta potential analysis, in vitro drug release, and in vitro cytotoxicity studies on HCT-15 colorectal adenocarcinoma cells.Results: The results showed that the particle size, morphological character and zeta potential value of optimized batch P-SLN were 265 nm, spherical and −26.5 Mv, respectively. The in vitro drug profile of P-SLN exhibited that it produced sustain drug release, and the cell viability of HCT-15 against P-SLN shown better efficacy than pure papain enzyme.Conclusion: P-SLNs were successfully prepared and investigated the in vitro drug release and in vitro cell viability against HCT-15 cell line.
