Rezafen Jing(Rezafungin)He is a rising star in the field of antifungal drugs, briefly described as follows
feature |
description |
Drug category |
Echinococcin antifungal drugs |
mechanism of action |
Non competitive inhibition1,3-beta-β - glucan synthase, which destroys fungal cell walls |
Core strengths |
Long lasting effect: with a half-life of approximately133Hours, allowing weekly administration, DIAN replaces the traditional mode of daily administration of echinocandin |
Main indications |
Adult candidemia and invasive candidiasis |
Efficacy verification |
IIIPhase clinical trials(ReSTORE)Confirmed that its efficacy is non inferior to the standard treatment drug caspofungin (once daily) in the primary endpoint |
Drug susceptibility testing |
Provide clear medication guidance for clinical doctors, especially for strains such as Candida albicans and Candida auricula that are prone to drug resistance or highly resistant |
💊Epidemiological and treatment challenges faced
Invasive Candida infection(ICIs)The epidemiology of COVID-19 has undergone significant changes in the past few decades, mainly reflected in:
→ Changes in bacterial strainsThe source of infection is increasingly shifting from traditional Candida albicans tonon-albicans candidaSpecies such as Candida albicans and Candida auricula are typically more resistant to antifungal drugs.
→ high mortality rateDespite treatment options, the mortality rate of invasive candidiasis remains high, reaching up to30%-40%It is a serious threat to the lives of critically ill patients.
Treatment dilemmaThe existing drugs have limitations, such as requiring daily intravenous administration, which poses challenges to medical resources and patient compliance.
💎Summary and Outlook
Overall, Reza Fenjing relies on itsLong term weekly effectThe administration method and good efficacy and safety demonstrated in phase III clinical trials provide a new important option for the treatment of invasive Candida infections.
ButDrug sensitivity testing is the "eye" that ensures the scientific and rational use of this new drugBy guiding clinical medication through drug sensitivity testing, ZUI can maximize the therapeutic potential of remifentanil and cope with the increasingly severe drug resistance
