Preparation method of drug carried microsphere capable of being positioning injected into tumor cavity

The invention relates to a preparation method of a drug carried microsphere capable of being positioning injected into a tumor cavity. When in a reaction process, the nano drug carried microsphere is prepared through a nano precipitation method by adopting polylactic acid as a carrier of an anti-cancer drug taxol and adopting bovine serum albumin as surfactant. Under an opsonic action of a reticuloendothelial system, after the drug is packed by polymer, the pharmacokinetic behaviors of the drug in vivo are always changed. The nano microsphere can be prepared into a slow-releasing preparation so that the half life of the drug in vivo is changed and the drug action time is prolonged; therefore, on condition of ensuring the drug effect, the dosage of the drug is reduced, and adverse effects are reduced or eliminated. Synchronously, the BSA (Bovine Serum Albumin) is served as external water phase to prepare polylactide particles, the bovine serum albumin can be absorbed on the surface of the microspheres so as to be easy to be identified by the reticuloendothelial system and absorbed by liver, therefore, the drug carried microspheres are gathered at the liver, the drug is slowly released at the liver, and the action time of the drug is prolonged.

Nano microcapsule for six ingredients with rehmannia and preparation process thereof

The invention discloses a nano microcapsule for six ingredients with rehmannia and a preparation process thereof. The preparation process comprises the following steps of: taking the traditional pills for six ingredients with the rehmannia as a basis, adopting a multilevel dynamic hot reflux method for extraction and concentration of radix rehmanniae preparata, Poria cocos and rhizoma alismatis; carrying out nano-level crushing on dogwood, tree peony bark and yam; and uniformly mixing the nano fine powder and concentrated liquor according to certain proportion, carrying out freezing or spray-drying treatment, preparing the nano microcapsule, and finally adopting a corresponding preparation technology to prepare into a dosage form applicable on clinic. The process has the advantages of simple operation, short process flow, easy control of parameters, low cost, no toxic and side effects caused by organic reagents and the like. The nano microcapsule for six ingredients with the rehmannia can be directly used, and also can be used as a drug intermediate. In the nano microcapsule, the drug effect can be obviously delayed, the administration times and amount can be reduced, and the toxic and side effect caused by the traditional drug is reduced or eliminated. The nano microcapsule is concentrated by more than three times compared with the existing nano microcapsule product for six ingredients with the rehmannia on the market, and the total daily dosage can be reduced by 3-6 times compared with the traditional products such as the concentrated six ingredients with the rehmannia and the like.
