The microemulsion formulation was composed of soybean oil, lecithin, T ween 80, ethanol, and water. Characterization of the microemulsions was carried out by means of particle size, viscosity, conductivity, storage stability, in vitro drug release, and in vitro hemolysis. Putative anticancer activity was determined using C alu1 and A 549 carcinoma cell lines with an XTT [2,3‐bis‐(2‐methoxy‐4‐nitro‐5‐sulfophenyl)‐2H‐tetrazolium‐5‐carboxanilide] cell proliferation assay. Drug release from the MMC ‐loaded microemulsion was sustained for more than 5 h while release from MMC solution was completed within 2 h. Based on the results of cytotoxicity study, a higher anticancer effect was observed with mitomycin C ‐loaded microemulsion ( MMC ‐ M ), with IC 50 values being approximately twofold to fourfold higher than that seen with the MMC solution on C alu1 and A 549 carcinoma cell lines, respectively. In conclusion, MMC microemulsion has several advantages including slower drug release, a more pronounced anticancer effect at lower MMC doses, potentially leading to lower systemic toxicity potential if leakage occurs from the tumor site.
