Successive additions of methyl oleate epoxide and H were made to the βCDs, and the reaction was carried out by vibrating ballmilling (VBM) in a mixer mill (volume of 65 mL) containing 12 stainless steel balls (3 balls with diameter of mm, 5 balls with diameter of mm, and 4 balls with diameter of mm).
This mill has been successfully employed for the production of nanoparticles of albendazole, danazol and omeprazole as well as probucol [87] for the enhancement of their dissolution and absorption properties. A major drawback of media milling is the erosion of the balls arising from the intensive mixing forces in the vessel.
