    • A W/O/W type composite emulsion, wherein a W/O type emulsion containing water, an oil ingredient and a lipophilic emulsifier each in a proportion expressed in term of mass ratio falling within a range enclosed with bold lines in FIG. 1 is dispersed in an external aqueous phase with a water-soluble macromolecule blended therein has a sufficient stability, and permits preserving a percent inclusion of medical substances included in an internal aqueous phase of the W/O/W type composite emulsion at a high level.Because of the characteristics, it is now possible to blend in a liquid formulation medical substances having an unfavorable taste or unstable medical substances which have to date hardly been included in liquid formulations with low viscosity, so that the W/O/W type composite emulsion can be utilized for liquid formulations including a liquid formulation for internal application, injections, etc.
    • 一种W / O / W型复合乳液,其中含有水,油成分和亲脂性乳化剂的W / O型乳液,其按质量比表示的比例落在图1中粗线所示的范围内。 1分散在外部水相中,其中混合的水溶性高分子具有足够的稳定性,并且允许在W / O / W型复合乳液的内部水相中包含的药物的含量百分比保持在高水平 。 由于这些特征,现在可以将具有不利味道的液体制剂医药物质或不稳定的医药物质混合在一起,这些物质几乎不被包含在具有低粘度的液体制剂中,使得W / O / W型复合乳液 可用于液体制剂,包括用于内部应用的液体制剂,注射剂等。
