More Information
Summary:The present invention provides a pharmaceutical emulsified preparation and manufacturing method thereof. Although the pharmaceutical emulsified preparation is a stable emulsion, it will release the pharmaceutical ingredients in inner aqueous phase after medication for the patient thereby achieving the treatment effect to hepatocellular carcinoma. To solve the problem, there is provided a w/o/w type emulsion preparation, in which its inner aqueous phase is a water solution containing pharmaceuticals and its outer aqueous phase is dispersed with w/o oil drops. The w/o oil drops are formed by containing polyoxyethylene hardened castor oil in oil phase as surfactant, wherein the additive mole number of ethylene oxide of the polyoxyethylene hardened castor oil is more than one and less than nine.
