Abstract

The invention provides an iseganan quick-release film agent. The film agent is prepared from the following raw materials in percentage by weight: 0.001-0.3 percent of iseganan, 30-80 percent of a film forming agent, 0.01-9 percent of plasticizer, 0.2-3.0 percent of a flavoring agent, 0.02-0.5 percent of surfactant, 0-20 percent of filler and the balance of a buffer solution. The quick-release film agent can be quickly released in 1 minute, so that antimicrobial peptide can quickly reach high concentration in an administration position, and the bacterium resisting and inhibiting effect can be effectively achieved.

Description

technical field [0001] The present invention relates to an immediate-release film preparation of Estherginam. Background technique [0002] Amino acid sequence H-Arg-Gly-Gly-Leu-Cys-Tyr-Cys-Arg-Gly-Arg-Phe-Cys-Val-Cys- Val-Gly-Arg-NH2 (5-14,7-12; disulfide bond), the molecular formula is C 78 h 126 N 30 o 18 S 4 , with a molecular weight of 1900.29 Iseganan is an analogue of porcine neutrophil peptide-1 (protegrin-1, PG-1), which can combine with bacterial extracellular components such as lipopolysaccharide or lipid membrane acid to cause bacterial swelling and rupture , kills bacteria by disrupting cell membranes. [0003] Due to its unique mechanism of action, Eserginan has broad-spectrum bactericidal properties against oral microorganisms, does not produce drug resistance, has no toxic and side effects, and has the potential to replace traditional antibiotics. In vitro studies have shown that it has inhibitory effects on Gram-positive and negative bacteria and fung...
