oteseconazole

What is oteseconazole, and what is it used for?

Oteseconazole is a systemic antifungal medication used to treat recurrent vulvovaginal candidiasis in women without reproductive potential.

Candidiasis is a type of yeast infection caused by Candida species of fungi. Oteseconazole may be used as monotherapy or in combination with fluconazole, another systemic antifungal medication.

Oteseconazole is a synthetic azole metalloenzyme inhibitor that works by inhibiting the activity of a fungal enzyme essential for fungal survival and growth. Oteseconazole selectively inhibits fungal sterol 14-alpha demethylase (CYP51), an enzyme essential for the formation and integrity of the fungal cell membrane. The inhibition of CYP51 results in the accumulation of 14-alpha methylated sterols which are toxic to fungi.

Oteseconazole is active against the following Candida species of fungi associated with recurrent vulvovaginal candidiasis:

• Candida albicans
• Candida glabrata
• Candida krusei
• Candida parapsilosis
• Candida tropicalis
• Candida lusitaniae
• Candida dubliniensis

Warnings

• Do not use in patients with known hypersensitivity to oteseconazole or any of its components.
• Do not use in women of reproductive potential or women who are pregnant or breastfeeding.
