| titleOfInvention | Biodegradable polymer microspheres capable of continuously controlled controlled release and preparation method thereof |
| abstract | The present invention relates to a microsphere made of a biodegradable polyester-based polymer capable of continuously controlling drug release and increasing the amount of drug encapsulated in the microsphere and a method for preparing the same, which is a drug in a biodegradable polyester-based polymer carrier. By encapsulating the biodegradable polyester-based polymer and the drug through covalent bonding, the drug release rate can be controlled according to the decomposition rate of the biodegradable polyester-based polymer regardless of the diffusion concentration of the drug. As well as to obtain the effect of encapsulating a larger amount of hydrophilic drug in the same size microspheres, the covalent bond of the biodegradable polyester-based polymer and the drug is to preactivate the drug having a functional group and the polymer To the polymer, coupling agents, bases, linkers, spacers Or by adding a multiligand compound to preactivate the polymer and then binding the desired drug. |
