Abstract

The invention discloses an anti-HPV (human papilloma virus) polyphenol sustained-release lipid nanoparticle gel and a preparation method thereof, the preparation is mainly used for vaginal administration, mucous membrane administration or skin administration, is used for inhibiting papilloma virus infection, and belongs to the technical field of medicines. The invention relates to an anti-HPV (human papillomavirus) polyphenol sustained-release lipid nanoparticle gel, which is prepared from the following raw materials in parts by weight: 1 part of polyphenol, 1-5 parts of lipid component, 1-3 parts of soybean phospholipid, 1-3 parts of poloxamer, 2-6 parts of polycarbophil, 1-3 parts of carbomer, 5-10 parts of liquid paraffin and 22-28 parts of glycerol. The anti-HPV (human papilloma virus) polyphenol sustained-release lipid nanoparticle gel has the advantages that polyphenol medicine components can be slowly released, medicine adhesion is kept without flowing out, a certain medicine concentration is kept in a local environment and mucous membranes or skin layers, and the effect of inhibiting HPV viruses and infected cells is improved.

Description

technical field [0001] The present invention relates to an anti-HPV virus drug for vaginal administration, mucous membrane or skin administration, in particular to an anti-HPV virus polyphenol slow-release lipid nanoparticle gel for local treatment and prevention of human nipple The invention relates to warts and cervical cancer diseases caused by tumor virus HPV, belonging to the technical field of medicine. Background technique [0002] HPV mainly infects human skin epithelium and mucosal epithelium. HPVE1 and E2 proteins regulate the replication and transcription of the viral genome, E4 protein assists virus maturation, and high-risk HPVE5, E6, and E7 are the main factors that cause cancer. Immortalization plays a decisive role. The persistent infection of HPV virus can lead to the integration of HPV DNA into human cells. The integration of HPV DNA often results in the deletion of E1 and E2 regions in cervical cells, which in turn leads to the persistent high expression ...
