Itraconazole
Itraconazole 100mg or 200mg Capsules
Itraconazole is a potent antifungal medication belonging to the class of triazole agents. It is widely used to treat a broad spectrum of fungal infections affecting the skin, nails, and internal organs. It works by inhibiting ergosterol synthesis, an essential component of the fungal cell membrane, thereby stopping fungal growth and clearing the infection.
Some Therapeutic Uses Include:
Fungal Nail Infections (Onychomycosis): Treats severe infections of fingernails and toenails.
Skin Infections: Effective against ringworm (Tinea corporis), athlete’s foot (Tinea pedis), and jock itch (Tinea cruris).
Oral & Vaginal Thrush: Treats candidiasis affecting the mouth, throat, or vaginal area.
Systemic Infections: Used for serious internal infections like aspergillosis and histoplasmosis, especially in immunocompromised patients.
Dosage Administration Guide
With a Full Meal: Capsules must be taken immediately after a full meal to ensure proper absorption in the presence of gastric acid.
Avoid Antacids: Do not take antacids within 2 hours, as they reduce stomach acidity and decrease drug absorption.
Swallow Whole: Do not crush or chew the capsules, as this affects drug release and pharmacokinetics.
Complete the Course: Continue the full prescribed duration, even if symptoms improve early, to prevent recurrence.
