Itraconazole

ANTIFUNGAL

Uses of Itraconazole

  • Itraconazole is used to treat fungal infections in the lungs that can spread throughout the body. 
  • It is primarily used to treat pulmonary and extrapulmonary forms of blastomycosis, histoplasmosis (including chronic cavitary pulmonary disease and disseminated nonmeningeal histoplasmosis), pulmonary and extrapulmonary aspergillosis, and onychomycosis (fungal nail infections). 
  • Itraconazole is particularly effective in patients who are intolerant to amphotericin B therapy.

Side effects of Itraconazole

  • Stomach pain 
  • Nausea
  • Headache

How Itraconazole works

  • Itraconazole falls under the triazole antifungal category.
  • It interferes with the synthesis of ergosterol, a crucial component of fungal cell membranes. This disruption weakens the fungal cell membrane, making it more susceptible to damage. By inhibiting ergosterol production, itraconazole inhibits fungal growth. Without a stable cell membrane, fungi struggle to maintain their structural integrity and reproduce. It further disrupts fungal cell function by affecting various enzymes and processes. This damages the fungal cell's ability to carry out essential functions, ultimately leading to its death.
