Abstract

The invention relates to the technical field of medicines, in particular to new application of theaflavin as a synergist of antifungal drugs. Through in vitro experiments, when used together with fluconazole, itraconazole, miconazole, ketoconazole and other antifungal drugs, theaflavin can increase therapeutic effect on slight surface and deep fungus infection to some extent and can restore the effect of the antifungal drugs on drug-resisting fungi. Therefore, the theaflavin can be used as the synergist of the antifungal drugs. The invention provides new application for the theaflavin; when used as the synergist of the antifungal drugs, the theaflavin not only can increase the antifungal effect of the drugs, but also can restore the effect of the antifungal drugs on the drug-resisting fungi in the condition that clinic fungal drug resistance is more and more common and drug resistance degree is more and more serious. The application dosage of the antifungal drugs can be reduced, so that medical expenses can be saved for patients, and the toxic and side effects of the drugs are reduced.

Description

technical field [0001] The invention relates to the technical field of medicine, and relates to a new application of theaflavin as a synergist for antifungal drugs. Background technique [0002] Theaflavin is one of the tea polyphenols. Studies have shown that theaflavin has the effect of regulating blood lipids, preventing cardiovascular diseases, and has a unique function of lowering blood lipids. Theaflavins are not only an effective free radical scavenger and anti Oxidant, and has various physiological functions such as anti-cancer, anti-mutation, improvement and treatment of cardiovascular and cerebrovascular diseases, and treatment of diabetes. Its role in food, medicine and health care is becoming more and more prominent. Theaflavins also have antibacterial effects, but have no antifungal effects, and there are no reports of their combined use as a synergist and antifungal drugs to treat fungal diseases. Contents of the invention [0003] The invention provides a n...
