Currently, several new drug families like echinocandins and flucytosine have also entered the market with increasing prominence. The mode of action for antifungal drugs is either to inhibit the cell wall biosynthesis or to interfere with cellular division. However, despite new drugs being discovered, resistance to antifungal agents makes the search for newer, better and faster-acting drugs a necessity.
