Product Name:
CAS Number:
For use in the treatment of candidemia, acute disseminated candidiasis, and certain other invasive Candida infections, as well as esophageal candidiasis, and prophylaxis of Candida infections in patients undergoing hematopoietic stem cell transplantation. Micafungin is also used as an alternative for the treatment of oropharyngeal candidiases and has been used with some success as primary or salvage therapy, alone or in combination with other antifungals, for the treatment of invasive aspergillosis.
Mode of Action:

Micafungin is a glucan synthesis inhibitor of the echinocandin structural class and can be used safely alongside other drugs such as HIV and transplant drugs.


As a semisynthetic lipopeptide Micafungin is an antifungal agent. Micafungin works by inhibiting the enzyme needed for fungal cell-wall synthesis.


In vitro Micafungin is highly protein bound with the primary binding protein being albumin. The half-life of Micafungin is between 14 and 17 hours.


Dose-limiting toxicity has not been found in adult patient clinical trials. The minimum lethal dose of Micafungin is 125 mg/kg in rats, which is 8.1 times the recommended clinical human dose. Severe adverse effects from Micafungin are uncommon, with patients reporting minor side effects like headache, mild itching, slight nausea and flushing.
