NS-IT200

About

Itraconazole is a synthetic triazole antifungal agent with a broad spectrum of activity against various fungal pathogens, including dermatophytes, yeasts, and dimorphic fungi. It exerts its antifungal effect by inhibiting the fungal cytochrome P450-dependent enzyme 14-alpha-demethylase, which is crucial for ergosterol synthesis, a vital component of the fungal cell membrane. This inhibition leads to structural and functional impairment of the fungal cell membrane, ultimately resulting in fungal cell death.

The 200mg dosage is commonly used for systemic fungal infections, including aspergillosis, blastomycosis, histoplasmosis, and onychomycosis. Itraconazole exhibits high lipophilicity and keratin affinity, allowing for sustained drug levels in skin and nails. Its complex pharmacokinetics necessitate careful dosing and monitoring, especially due to potential drug interactions and adverse effects.

Uses

• Treatment of systemic fungal infections like aspergillosis.
• Management of blastomycosis and histoplasmosis.
• Therapy for onychomycosis (fungal nail infections).

Safety Measures

• Alcohol - Concurrent use of alcohol with itraconazole may increase the risk of liver toxicity and gastrointestinal upset. It is generally advisable to avoid or limit alcohol consumption.
• Pregnancy - Itraconazole is contraindicated during pregnancy due to potential teratogenic effects. Effective contraception must be used by women of childbearing potential during and after treatment.
• Breastfeeding - Itraconazole is excreted into breast milk. Breastfeeding is not recommended during treatment with itraconazole.
• Liver - Use with extreme caution in patients with pre-existing liver disease, as itraconazole can cause severe hepatotoxicity. Monitor liver function tests regularly.
• Kidney - Use with caution in patients with renal impairment. Dose adjustment may be necessary, and monitoring of drug levels might be considered.
• Lung - Contraindicated in patients with a history of congestive heart failure or ventricular dysfunction, as it can exacerbate these conditions. Use with caution in patients with underlying lung disease.
