  • Patent number: 10835511
    Abstract: 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).

  • Publication number: 20200332789
    Abstract: A fluid delivery system is revealed. A double diaphragm pump provided with two inlets and two outlets is mounted in the fluid delivery system. An introducing pipeline is connected to one set of inlet and outlet while a return pipeline is connected to the other set of inlet and outlet. Thereby a pneumatic mechanism in the double diaphragm pump drives two diaphragms therein to draw in and expel fluid in the system so that the fluid flows in and out through the two sets of inlets and outlets. Thus the pressure remains constant and the volume flow rate is uniform during delivery and returning of the fluid. A drain-back tube provided with a control valve is arranged between the introducing pipeline and the return pipeline. The fluid is returned and delivered under control of the control valve while changing fluids or cleaning pipelines of the system.
