🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Itraconazole, the active ingredient in this medicine, is a triazole antifungal agent that inhibits the fungal cytochrome P450 enzyme 14α-demethylase. This enzyme is responsible for converting lanosterol to ergosterol, a critical component of the fungal cell membrane. By inhibiting this step, itraconazole disrupts the synthesis of ergosterol, leading to increased membrane permeability and leakage of cellular contents, ultimately causing fungal cell death. This medicine is applied topically to the eye, allowing direct contact with the infected corneal tissue.
