Itraconazole Capsules 100 mg – Effective Oral Antifungal Treatment

Itraconazole Capsules 100 mg are a powerful oral antifungal medication used to treat a variety of fungal infections affecting the skin, nails, lungs, and other organs. Belonging to the azole antifungal class, itraconazole works by inhibiting the growth of fungi, making it effective against both superficial and systemic fungal infections.

This medication is often prescribed for difficult-to-treat fungal infections where topical treatments are insufficient, or when infection has spread beyond the surface. It offers a convenient oral therapy option that penetrates tissues effectively to eliminate fungal pathogens.

What Are Itraconazole Capsules 100 mg Used For?

Itraconazole 100 mg capsules are indicated for the treatment of:

• Blastomycosis, histoplasmosis, and aspergillosis (serious systemic fungal infections)
• Onychomycosis (fungal nail infections)
• Tinea infections such as athlete’s foot, ringworm, and jock itch
• Candidiasis involving mucous membranes and esophagus
• Fungal infections in immunocompromised patients

How Does Itraconazole Work?

Itraconazole works by blocking the synthesis of ergosterol, an essential component of fungal cell membranes. This disruption weakens the cell membrane and inhibits fungal growth, ultimately causing fungal cell death.

Mechanism Highlights:

• Selective inhibition of fungal cytochrome P450 enzyme
• Disrupts fungal cell membrane integrity
• Broad-spectrum antifungal activity

Dosage and Administration

The usual dose of Itraconazole Capsules 100 mg depends on the infection type and severity. Common regimens include:

• Onychomycosis: 200 mg daily in one or two divided doses for 6–12 weeks
• Systemic fungal infections: 200–400 mg daily based on clinical response
• Superficial fungal infections: 100–200 mg daily for 2–4 weeks

Capsules should be taken with food or a full meal to improve absorption. Avoid taking with antacids or medications that reduce stomach acid around the same time.
