VITAMIN K2 MICROSPHERES
A vitamin K2 microsphere. The microsphere includes a poly(lactide-co-glycolide) acid (PLGA) particle, in which the Mw of PLGA is between 1000 and 300000, and the molar ratio between the lactide repeat units and the glycolide repeate unit is 1-9:9-1; and one or more vitamin K2 molecules are embedded...

Zusammenfassung: | A vitamin K2 microsphere. The microsphere includes a poly(lactide-co-glycolide) acid (PLGA) particle, in which the Mw of PLGA is between 1000 and 300000, and the molar ratio between the lactide repeat units and the glycolide repeate unit is 1-9:9-1; and one or more vitamin K2 molecules are embedded in the PLGA particle, wherein the vitamin K2 is present in an amount of 0.005-75 wt %, based on the weight of the microsphere. Also disclosed are a method of preparing the vitamin K2 microsphere, a method of treating osteoporosis using this microsphere, and a pharmaceutical composition containing the microsphere. |
