Description: Micafungin is an echinocandin antifungal. It works by inhibiting 1,3-β-D-glucan synthase resulting in reduced formation of 1,3-β-D-glucan which is an essential polysaccharide comprising 30-60% of Candida cell walls; decreased glucan content results in osmotic instability and thus cellular lysis.


Absorption: Absorbed from the GI tract after oral admin.

Distribution: >99% bound to plasma proteins, mainly albumin.

Metabolism: Metabolised by arylsulfatase to its catechol form; further metabolised by catechol-O-methyltransferase to the methoxy form.

Excretion: Mean half-life: About 14-17.2 hr. Excreted mainly in the faeces.

This medication is used to treat a variety of fungal infections (such as candidemia, esophageal candidiasis). It is also used to prevent fungal infections if you are having a bone marrow or stem cell transplant, since people with weak immune systems have a higher risk of fungal infections.
