🩹 3. Main Uses

Itraconazole 200 mg is used to treat a range of fungal infections, including:
• Dermatophytoses (e.g., ringworm, athlete’s foot)
• Onychomycosis (fungal infections of nails)
• Oropharyngeal and esophageal candidiasis (thrush)
• Vulvovaginal candidiasis (yeast infections)
• Systemic and deep fungal infections (e.g., aspergillosis, histoplasmosis in lungs or other

features of Itraconazole 100 mg capsules — a commonly prescribed oral antifungal medicine:

✅ 1. Active Ingredient & Drug Class

• Contains itraconazole 100 mg, a triazole antifungal.

• Belongs to the systemic antifungals that inhibit fungal growth by targeting cell membrane synthesis.

✅ **2. Mechanism of Action

• Works by inhibiting fungal 14α-demethylase (a cytochrome P450 enzyme), preventing ergosterol production — an essential component of fungal cell membranes.

• This disruption weakens the membrane, increasing permeability and leading to fungal cell death.

✅ **3. Indications (What It’s Used For)

Itraconazole 100 mg is used (under a doctor’s prescription) to treat a range of fungal infections, including:

• Dermatophyte and yeast infections (skin, nails) such as onychomycosis.

• Mucosal fungal infections (oral or vaginal candidiasis).

• Systemic and deep fungal infections (e.g., aspergillosis, histoplasmosis, blastomycosis) in selected cases under supervision.

✅ **4. Pharmacokinetic Features

• Oral absorption: Readily absorbed; taking it with food improves bioavailability.

• Distribution: High tissue penetration, especially in skin and nails, which helps in treating difficult infections like nail fungus.

• Half-life: Has a relatively long elimination half-life, meaning it stays active in the body for extended periods with repeated dosing.

✅ **5. Convenience & Administration

• Oral capsule form makes it convenient compared with intravenous antifungals.

• Capsules should be swallowed whole with water and taken after a meal for best absorption.

✅ **6. Spectrum of Activity

• Broad-spectrum antifungal action — effective against dermatophytes, yeasts like Candida, and some molds.
