From the Guidelines

Cresemba is the brand name for isavuconazole, an antifungal medication used to treat serious fungal infections, specifically invasive aspergillosis and mucormycosis, as recommended by recent guidelines 1.

Key Points

  • Cresemba works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, causing the fungal cells to become unstable and die.
  • The medication is typically administered first as an intravenous infusion (200 mg every 8 hours for 6 doses), followed by either continued IV therapy or oral capsules (200 mg once daily) 1.
  • Common side effects include nausea, vomiting, diarrhea, headache, and elevated liver enzymes.
  • Patients should be aware that Cresemba can interact with many other medications, so it's essential to inform healthcare providers about all current medications.
  • Regular monitoring of liver function is typically recommended during treatment with this medication.

Administration and Monitoring

  • The dosage and administration of Cresemba may vary depending on the specific fungal infection being treated and the patient's individual needs.
  • Therapeutic drug monitoring (TDM) is not routinely recommended for isavuconazonium sulfate, as studies have not defined a therapeutic range for this medication 1.
  • However, TDM may be considered for other antifungal medications, such as posaconazole, voriconazole, and itraconazole, to ensure adequate plasma drug concentrations and reduce toxicity.

Recent Guidelines and Recommendations

  • Recent guidelines from the Infectious Diseases Society of America and other organizations recommend the use of Cresemba as a primary therapy for invasive aspergillosis and mucormycosis, due to its efficacy and safety profile 1.
  • The guidelines also emphasize the importance of early initiation of antifungal therapy, surgical debridement, and combination therapy in certain cases to improve patient outcomes.
