Description
Flucytosine Product Overview
Flucytosine (C4H4FN3O) is a white to off-white crystalline powder that is sparingly soluble in water. Inside fungal cells, it is converted to Fluorouracil, which disrupts fungal DNA and RNA synthesis.
Pharmaceutical companies use it in capsules and infusion solutions. Because fungi can quickly develop resistance when it is used alone, it is almost always combined with other antifungals, such as amphotericin B or Fluconazole, particularly for cryptococcal infections. It is on the WHO Model List of Essential Medicines, which has increased demand for affordable generic supply.
Zyntex supplies it from qualified API producers, only to licensed pharmaceutical companies. Other antifungal APIs in our range include Nystatin and Griseofulvin.
