Mechanism of action

The drug produces its fungicidal action by blocking the essential component present in the fungal cell membrane  i.e ergosterol by inhibiting the sequence of monooxygenase . Thus the decreased amount of ergosterol and monooxygenase causes accumulation of the sequences and contributes to its anti-fungal activity.

About 99% of the drug is bound to the plasma protein and metabolism of the drug is through hepatic enzymes i.e cytochrome P 450. The drug attains its half life in 36 hrs.
