Microbiology
Mechanism of Action
Ketoconazole blocks the synthesis of ergosterol, a key component of the fungal cell membrane, through the inhibition of cytochrome P-450 dependent enzyme lanosterol 14α-demethylase responsible for the conversion of lanosterol to ergosterol in the fungal cell membrane. This results in an accumulation of methylated sterol precursors and a depletion of ergosterol within the cell membrane thus weakening the structure and function of the fungal cell membrane.
Activity In Vitro and In Vivo
Ketoconazole tablets USP, 200 mg are active against clinical infections with Blastomyces dermatitidis, Coccidioides immitis, Histoplasma capsulatum,Paracoccidioides brasiliensis.[1]
