  • Publication number: 20230310401
    Abstract: Disclosed is a pharmaceutical composition containing dabigatran etexilate and a preparation method thereof. The pharmaceutical composition comprises a pharmaceutically active ingredient, dabigatran etexilate and/or dabigatran etexilate mesylate, an amphiphilic polymer of polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer, and a hydrophilic polymer of polyoxyethylene-polyoxypropylene glycol block copolymer. The mass percentage of the active pharmaceutical ingredient in the pharmaceutical composition is 5 wt % to 60 wt %; the mass percentage of the amphiphilic polymer in the pharmaceutical composition is 3 wt % to 40 wt %; and the mass percentage of the hydrophilic polymer in the pharmaceutical composition is 10 wt % to 90 wt %. The pharmaceutical composition not only increases the bioavailability of the pharmaceutically active ingredient, but also reduces absorption variability, and provides a more stable concentration of dabigatran in plasma, thereby reducing adverse side effects.

  • Patent number: 11707455
    Abstract: Disclosed is a pharmaceutical composition containing dabigatran etexilate and a preparation method thereof. The pharmaceutical composition comprises a pharmaceutically active ingredient, dabigatran etexilate and/or dabigatran etexilate mesylate, and a amphiphilic polymer of polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer. The mass ratio of the two is 1:0.23 to 1:3. The pharmaceutical composition not only increases the bioavailability of the pharmaceutically active ingredient, but also reduces absorption variability, and provides a more stable concentration of dabigatran in plasma, thereby reducing adverse side effects.

  • Patent number: 11628360
    Abstract: A method and apparatus for controlling game applications are provided. In the method, when an operating system receives a game starting command, the operating system determines a manner to start a corresponding game application according to whether the game application has resided in a memory, and when a cold boot manner is used, the operating system triggers the game application to report an amount of memory required currently by the game application, and determines whether a requirement of running the game application is met according to the amount of memory required and an amount of memory currently used, or the operating system ensures to meet the requirement of running the game application through background application freezing and clearing.
