    • The present invention relates to a pharmaceutical composition containing cyclosporin. More specifically, the present invention relates to a pharmaceutical composition containing cyclosporin, an oil component, a hydrophilic cosurfactant consisting of propylene carbonate or a mixture of propylene carbonate and polyoxyethylene-polyoxypropylene block copolymer, and a surfactant. The composition of the present invention is characterized in that it can be dissolved in an external phase such as water, artificial gastric juice and intestinal juice, etc. to form a self-emulsion with mild stirring and therefore, by appropriately adjusting the constitutional ratio of each component the diameter of particles in the inner phase of the emulsion thus formed can be readily controlled to 100 nm or below. The composition of the present invention can be formulated into the oral preparations such as soft capsules, hard capsules sealed with gelatin bending at the conjugated portion, oral liquid preparations, etc. When the composition of the present invention using propylene carbonate or its mixture with polyoxyethylene-polyoxypropylene block copolymer in a liquid state at room temperature is formulated into the soft capsule, it provides some advantages that it can inhibit the change in the capsule appearance and the precipitation of active ingredient due to the change in the solvent content, reduces the manufacturing cost to provide an economical effect and is substantially less toxic, in comparison to the soft capsule using ethanol, transcutol, propylene glycol, glycofurol, dimethylisosorbide, etc., in the prior art.
    • 本发明涉及含有环孢菌素的药物组合物。 更具体地,本发明涉及含有环孢菌素,油成分,由碳酸丙烯酯或碳酸丙烯酯和聚氧乙烯 - 聚氧丙烯嵌段共聚物的混合物构成的亲水性辅助表面活性剂和表面活性剂的药物组合物。 本发明的组合物的特征在于,其可以溶解在诸如水,人造胃液和肠液等的外部相中以形成自乳状液,同时温和搅拌,因此通过适当地调节 如此形成的乳液的内相中的粒子的直径可以容易地控制在100nm以下。 本发明的组合物可以配制成口服制剂,例如软胶囊,用共轭部分弯曲的明胶密封的硬胶囊,口服液体制剂等。当使用碳酸丙烯酯或其与聚氧乙烯的混合物的本发明的组合物 在室温下处于液态的聚氧丙烯嵌段共聚物配制成软胶囊,其具有一些优点,可以抑制由于溶剂含量的变化引起胶囊外观的变化和活性成分的沉淀,减少制造 在现有技术中,与使用乙醇,转酮醇,丙二醇,糖醇,二甲基异山梨醇等的软胶囊相比,具有经济效果并且毒性大大降低的成本。

    • The present invention relates to a microemulsion preconcentrate composition comprising (1) cyclosporin as an active component; (2) alkyl ester of polycarboxylic acid and/or carboxylic acid ester of polyols as a lipophilic solvent; (3) oil; and (4) surfactant. The composition according to the present invention is characterized in that it dissolves in an external phase such as water, artificial gastric fluid and artificial intestinal fluid by controlling the mixing ratio of the components thereby to get the microemulsion form of inner phase diameter of 100 nm or below. The composition according to the present invention can be formulated as the dosage form of a soft capsule, a hard capsule sealed with a gelatin banding at the conjugated portion, or an oral liquid preparation for oral administration. Especially, if the cyclosporin microemulsion preconcentrate comprising cyclosporin, oil, lipophilic solvent and surfactant is formulated in a soft capsule according to the present invention, the resultant capsule removes the disadvantages of the prior arts showing the reactivity of hydrophilic solvent with gelatin shell of soft capsule and the volatility of hydrophilic solvent wherein the hydrophilic solvent was essential component in the composition according to the existing patents.
    • 本发明涉及一种微乳液预浓缩组合物,其包含(1)环孢菌素作为活性成分; (2)多元羧酸的烷基酯和/或作为亲脂性溶剂的多元醇的羧酸酯; (3)油; 和(4)表面活性剂。 根据本发明的组合物的特征在于通过控制组分的混合比例在水相,人造胃液和人造肠液等外界溶解,得到内相直径为100nm的微乳液形式,或 下面。 根据本发明的组合物可以配制成软胶囊的剂型,用共轭部分的明胶带密封的硬胶囊,或用于口服给药的口服液制剂。 特别地,如果将包含环孢菌素,油,亲脂性溶剂和表面活性剂的环孢菌素微乳液预浓缩物配制在根据本发明的软胶囊中,则所得胶囊消除了现有技术的缺点,显示亲水性溶剂与软胶囊明胶壳的反应性 和亲水性溶剂的挥发性,其中亲水性溶剂是根据现有专利的组合物中必需组分。
