    • A pharmaceutical composition comprises a taxane (e.g., paclitaxel, docetaxel, cabazitaxel, larotaxel, ortataxel, and/or tesetaxel) in a mixture of first and second surfactants. The absorption of the taxane is increased from the pharmaceutical composition is greater than the sum of the absorption of docetaxel from either the first or the second surfactant. The increase in absorption is especially enhanced when the ratio of the first surfactant to the second surfactant in the pharmaceutical composition is between 60:40 and 85:15 by weight, and the total surfactant weight does not exceed 98%of the total weight. Polysorbate 80, polysorbate 20, and caprylocaproyl polyoxylglycerides serve as suitable first surfactants, and polysorbate 80 or polyethyoxylated castor oil serve as suitable second surfactants. The stability of the pharmaceutical composition may be enhanced by further including a stabilizer (e.g., citric acid and/or ascorbic acid).
    • 药物组合物包含在第一和第二表面活性剂的混合物中的紫杉烷(例如紫杉醇,多西紫杉醇,卡巴他赛,拉罗哌赛,奥他他和/或替西他赛)。 紫杉烷的吸收从药物组合物的增加大于多西他赛从第一或第二表面活性剂的吸收的总和。 当药物组合物中第一表面活性剂与第二表面活性剂的重量比在60:40至85:15之间时,吸收的增加尤其增加,总表面活性剂重量不超过总重量的98%。 聚山梨醇酯80,聚山梨醇酯20和辛酰己酰基聚氧乙烯甘油酯用作适合的第一表面活性剂,聚山梨醇酯80或聚乙氧基化蓖麻油用作合适的第二表面活性剂。 通过进一步包括稳定剂(例如柠檬酸和/或抗坏血酸)可以增强药物组合物的稳定性。
