Preparation method of emulsion for chemoembolization

摘要

A preparation method of an emulsion to be used in a chemoembolization which comprises the steps of mixing an aqueous contrast medium containing an anti-cancer agent as an inner aqueous phase and an oily contrast medium containing a surface active agent as an oil phase and then severely agitating the same. The thus obtained emulsion has an effect that the anti-cancer agent is released therefrom continuously and in a sustained manner due to its reduced difference in the viscosity between aqueous phase and oil phase.
