There is disclosed a medicinal composition comprising lipid, non-lipid liquid and pharmaceutical ingredients, characterized by the fact that the ingredients are emulsified and encapsulated in a gelatine capsule as a liquid and in a physical form capable of delivering the pharmaceutical in its unaltered original state to the brush layer of the small intestine; the non-lipid ingredient being water, a water substitute not attacked by lipid enzyme activity or a mixture of water substitute and water; and the total water in the emulsion is not more than 20%; the physical form of the ingredients is as follows:
(a) the lipid ingredient is in the form of individual globules predominantly of a size less than about 3 microns in diameter;
(b) each of the globules contains the pharmaceutical ingredient dispersed therein; and
(c) each of the globules is enveloped within a surrounding layer of said non-lipid liquid ingredient adhered to the globule by surface tension, the surrounding layer serving to maintain the globules in independent form and to present only the non-lipid liquid surface to the stomach fluids.
There is also disclosed a method of making same.
本发明公开了一种由脂质、非脂质液体和药物成分组成的药物组合物,其特征在于这些成分被乳化并以液体的物理形式封装在明胶胶囊中,能够以未改变的原始状态将药物输送到小肠刷状层;非脂质成分是
水、未被脂质酶活性攻击的
水替代物或
水替代物和
水的混合物;乳化液中的总
水分不超过 20%;成分的物理形式如下:
(a) 脂质成分主要呈直径小于约 3 微米的单个球状;
(b) 每个小球都含有分散在其中的药物成分;以及
(c) 每个球状物都被包在一层非脂质液体成分的周围层中,这层液体成分通过表面张力附着在球状物上,周围层的作用是保持球状物的独立形态,并使胃液只看到非脂质液体表面。
此外,还公开了一种制作方法。
