<p>Micafungin, as one of three echinocandina, has been proven to be a successful antifungal therapeutic in treating general Candida fungus infections. The treatment of immunocompromised patients is particularly important as Candida infections cause high mortality rates in patients in intensive care units, receiving chemotherapy, or stem cell transplants. This product acts as an anti-fungal by inhibiting the 1,3-beta-D-glucan synthase enzyme. As a result the production of 1,3-beta-D-glucan, which is crucial to the fungal cell wall, is hindered. Thus, the fungal cell wall loses integrity allowing for osmotic instability and cell lysis to occur.</p>
