Problems solved by technology

There are many reasons: high-density lipoprotein in blood is the main component that destroys liposomes; because it can activate the complement system, liposomes are easy to be penetrated and cracked; phospholipase can degrade phospholipids; serum albumin can combine with phospholipids to form complexes, thereby Decreased stability of nanoassemblies composed of phospholipids

Abstract

The invention relates to an irinotecan nano lipid binding preparation and a preparation method thereof. The irinotecan nano lipid binding preparation contains phospholipid, polyethylene glycol-dodecahydroxycy stearate, glycerol, ethanol and irinotecan, as well as an aqueous solvent for injection. The irinotecan nano lipid binding preparation is even in grain size, and as the lipid binding preparation, capable of reducing the toxicity of the irinotecan with long circulation effect and enhancing the tumor targeted enrichment effect and improving the compliance of a patient, and the preparation method is simple in process, high in repeatability and applicable to industrial production.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical nano-lipid bundle preparations, in particular to an irinotecan nano-lipid bundle preparation and a preparation method thereof. Background technique [0002] Irinotecan (CPT-11), which was approved by the FDA in 1998 for the standard chemotherapy regimen to treat the recurrence and exacerbation of metastatic colorectal cancer, is the re-approval of the US FDA after pentafluorouracil (5-FU) for more than 40 years Chemotherapy drugs for the first-line treatment of metastatic colorectal cancer. It is a derivative of camptothecin, which selectively binds and inhibits topoisomerase I, and covalently binds with the Topo-DNA complex to form a stable Topo-drug-DNA complex, thereby inhibiting the DNA reconnection step, so that the DNA strand cleavage, leading to apoptosis. It has a higher curative effect on small cell lung cancer, small cell lung cancer, cervical cancer, ovarian cancer and colorect...
