Astellas Pharma US, Inc. announced today the availability of their antifungal agent MYCAMINE® (micafungin sodium) for injection in a 100mg vial format. Approved in 2005 for the treatment of patients with esophageal candidiasis and prophylaxis of Candida infections in patients undergoing hematopoietic stem cell transplantation, MYCAMINE® was previously only available in a 50mg vial. The addition of this vial size will increase the convenience of use when administering MYCAMINE while decreasing waste in the hospital setting.

"The addition of the 100mg MYCAMINE vial provides physicians with a convenient option which may reduce waste in the clinical setting.

"From a pharmacist's perspective, the availability of MYCAMINE in a 100mg vial makes a big difference," stated Steven Gabardi, PharmD, BCPS, Organ Transplant Clinical Specialist, Brigham and Women's Hospital, Harvard Medical School. "Having this medication dosage format reduces storage space requirements and time spent on preparation. It is a little difference that will make a significant impact."

About MYCAMINE

MYCAMINE is a member of a new class of antifungal agents, the echinocandins. MYCAMINE inhibits an enzyme essential for fungal cell-wall synthesis and is fungicidal (lethal) for Candida. MYCAMINE can be used concomitantly with a variety of other drugs, including the HIV protease inhibitor ritonavir and the transplant medications cyclosporine and tacrolimus.
