What type of infections are echinocandins primarily used to treat?

Echinocandins are primarily used to treat yeast infections caused by Candida species. This class of antifungal agents works by inhibiting the synthesis of β-(1,3)-D-glucan, an essential component of the fungal cell wall, which is particularly significant in Candida infections. The efficacy of echinocandins against Candida species makes them a crucial option for the treatment of invasive candidiasis, especially in patients who are immunocompromised or have other risk factors.

While echinocandins may have some activity against other fungal pathogens, including certain molds, their primary indication remains focused on Candida infections. This specificity illustrates their targeted use in the clinical management of fungal diseases, particularly in cases that are resistant to other antifungal therapies.
