Abstract

The invention provides an iodized oil embolism agent containing adriamycin and a preparation method of the iodized oil embolism agent. The iodized oil embolism agent is prepared from composite gel powder, an anti-tumor drug and a magnetic nano material and iodized oil; the anti-tumor drug is loaded in composite gel; the magnetic nano material is loaded on the outer side of the composite gel; the preparation method comprises the steps that S1, bletilla striata gelatin, tripropylene gelatin, n-butyl methacrylate, polylactic acid and deionized water are mixed, then initiator alkenyl amide is added, drying and smashing are carried out after a stirring reaction, and composite gel powder is obtained; S2, the anti-tumor drug is added into the composite gel solution, and oscillating and stirring are carried out to obtain drug-loaded gel; S3, the magnetic nano material is dispersed into ultrapure water, a surfactant is added, the drug-loaded microspheres are added, stirring is carried out for reaction, and filtering is performed to obtain magnetic loaded microspheres; and S4, storing and taking are carried out.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation, and in particular relates to a doxorubicin-containing lipiodol embolism and a preparation method thereof. Background technique [0002] At the beginning of the 20th century, iodized oil came out as an X-ray contrast agent and became the first iodine contrast agent used in human organs. With the wide application of iodized oil, medical workers have found that iodized oil also has the effect of arterial embolism, and is the first choice for clinical chemoembolic agents. Iodized oil is a kind of poppy seed oil containing fatty acid ethyl ester, the mass fraction is 37%-41, it is opaque to X-ray, and it is often used as X-ray contrast agent in clinic. Lipiodol can selectively accumulate in the liver cancer tissue area, and at the same time, it has an embolism effect on blood vessels, and is often used as a suspending agent or marker for liver tumor treatment drugs. [0003] Once iodize...
