New pharmacotherapeutic strategies for drug-resistant candida infections: a review.

Introduction: Candida species produce a wide array of infections ranging from mucocutaneous to systemic infections. Candida albicans remains the most common species identified, however the non-albicans Candida species have continued to increase as the diagnosis and therapeutic regimens have progressed.

Areas covered: This review with discuss the various Candida species, especially the non-albicans species, some of the important mechanisms of resistance, and newer in vitro and clinical studies describing the recent and novel antifungal options such as rezafungin, ibrexafungerp, and oteseconazole, along with a novel antifungal, fosmanogepix.

Expert opinion: Initial antifungal therapy is frequently obsolete due to the expansion of antifungal resistance. This is especially true with C. glabrata, C. krusei, and most recently with C. auris. The newer and novel antifungals discussed here will add valuable tools to our antifungal armamentarium to be able to appropriately and adequately treat and manage these difficult infections. Each of the antifungals has unique and novel properties that will expand the arsenal useful to treat these fungal infections in the years to come.
