What are the uses of this medicine?

Micafungin (Mycamine) is used in adult and pediatric patients for:

• Treatment of Candidemia, Acute Disseminated Candidiasis, Candida Peritonitis and Abscesses in adult and pediatric patients 4 months of age and older.
• Treatment of Candidemia, Acute Disseminated Candidiasis, Candida Peritonitis and Abscesses without meningoencephalitis and/or ocular dissemination in pediatric patients younger than 4 months of age.
• Treatment of Esophageal Candidiasis in adult and pediatric patients 4 months of age and older.
• Prophylaxis of Candida Infections in adult and pediatric patients 4 months of age and older undergoing Hematopoietic Stem Cell Transplantation (HSCT).

Limitations of Use:

• The safety and effectiveness of MYCAMINE have not been established for the treatment of candidemia with meningoencephalitis and/or ocular dissemination in pediatric patients younger than 4 months of age as a higher dose may be needed.
• MYCAMINE has not been adequately studied in patients with endocarditis, osteomyelitis or meningoencephalitis due to Candida.
• The efficacy of MYCAMINE against infections caused by fungi other than Candida has not been established.

How does this medicine work?

• Micafungin is a member of the echinocandin class of antifungal agents.
• Micafungin inhibits the synthesis of 1,3-beta-D-glucan, an essential component of fungal cell walls, which is not present in mammalian cells.
• The echinocandins are a relatively new class of antifungal agents, whose activity is due to inhibition of glucan synthetase, the enzyme that is responsible for synthesis of β-1, 3-D-glucan, an essential component of the cell wall of filamentous fungi, such as Aspergillus and Candida species.
• This enzyme inhibition results in alteration in the fungal membrane integrity, followed by cell ballooning and, for Candida cells, lysis.

Who Should Not Use this medicine ?

This medicine cannot be used in patients with:

• known hypersensitivity to micafungin, any component of MYCAMINE, or other echinocandins.

What drug interactions can this medicine cause?

• Monitor for sirolimus, itraconazole or nifedipine toxicity, and dosage of sirolimus, itraconazole or nifedipine should be reduced, if necessary.

Is this medicine FDA approved?
