Background: Developing and evaluating a drug taken by mouth delivery method with mebendazole nanosuspension to treat intestinal worms infestations are the main objectives of the current research effort. This is because drug particles in the nano range help to reduce particle size and enhance dissolution. Methods: By using High pressure homogenization method, the mebendazole is converted into nanosuspension. Various amounts of HPMC K4M used as a stabilizer and Tween 80 and Poloxamer 188 used as a surfactant and compare its ratios. The results were investigated using effectiveness of drug entrapment, saturation solubility, zeta potential, particle size, drug release study and stability testing. Result: The drug purification results are shown by knowing the FT-IR spectrum. With a good entrapment efficiency and saturated solubility, optimized batches are found and the use of transmission electron microscopy confirms the nano size particle formed. The mebendazole nanosuspension showed higher release in the target site within 12 hours, according to an in-vitro dissolution experiment. Using the oral route for administration of the mebendazole nanosuspension, it increases the drugs absorption along with complete drug releasing. Conclusion: The study indicates that the prepared mebendazole nanosuspension has increased the rate of dissolution and solubility by converting nano range particles and encouraging the use of BCS class Ⅱ drugs with acceptable stability.
