Pharmacology
Formerly known as FK463, micafungin is a novel antifungal agent. It is a glucan synthesis inhibitor of the echinocandin structural class. The U.S. Food and Drug Administration approved micafungin in March 2005. Micafungin inhibits an enzyme essential for fungal cell-wall synthesis and is fungicidal (lethal) for Candida. Micafungin can be used concomitantly with a variety of other drugs, including the HIV protease inhibitor ritonavir and the transplant medications cyclosporine and tacrolimus.

side effects and Toxicity
Intravenous LD50 in rats is 125mg/kg. In dogs it is >200mg/kg. No cases of overdosage have been reported. Repeated daily doses up to 8 mg/kg (maximum total dose of 896 mg) in adult patients have been administered in clinical trials with no reported dose-limiting toxicity. The minimum lethal dose is 125 mg/kg in rats, equivalent to 8.1 times the recommended human clinical dose for esophageal candidiasis based on body surface area comparisons.
