Nystatin remains a critical antifungal agent primarily used in topical and oral formulations for managing candidiasis. Its formulation stability, patient compliance, and manufacturing efficiency depend heavily on excipient selection and innovation.
What is Nystatin’s Current Formulation Landscape?
Nystatin formulations typically include topical ointments, creams, powders, and oral suspensions. The oral form poses challenges due to its poor water solubility and stability in various pH conditions. Conventional excipients support drug stability, control release, and enhance bioavailability.
