This summary of a study originally published in the journal . The study took place in China and tested a medicine called isavuconazole on mold samples to check if isavuconazole can be used to treat mold infections. Isavuconazole became available in China in January 2022 as a capsule (a hard gel-covered pill filled with a dose of medicine) and in June 2022 as an injection or a shot. Isavuconazole stopped the growth of most molds. Other medicines were needed at higher amounts to stop the growth of molds. Isavuconazole is another option to treat mold infections in China.
