How Kronuz Capsule works

Kronuz 100mg Capsule contains Isavuconazole, an antifungal medicine that blocks the activity of an enzyme that aids in the synthesis of ergosterol, a key component of the fungal cell membrane. As a result, the fungus fails to grow and multiply. This kills the infection causing fungus and clears the infection.
