How does itraconazole work in treating onychomycosis?
Itraconazole treats onychomycosis by targeting the fungal cells causing the nail infection through a specific mechanism:
How Itraconazole Works for Onychomycosis
Class:
Itraconazole is a systemic antifungal from the azole class.
Mechanism of Action:
It inhibits the fungal enzyme lanosterol 14α-demethylase, which is crucial for converting lanosterol to ergosterol.
Ergosterol is an essential component of fungal cell membranes.
By blocking ergosterol synthesis, itraconazole disrupts the fungal cell membrane’s integrity and function.
Effect on Fungi:
Without ergosterol, the fungal cell membrane becomes unstable, increasing permeability.
This leads to leakage of cellular contents and ultimately fungal cell death or growth inhibition.
Pharmacokinetics and Nail Penetration:
Itraconazole is absorbed into the bloodstream when taken orally.
It concentrates well in keratin-rich tissues such as nails and skin, reaching the site of infection effectively.
This makes it particularly useful for nail infections where topical agents struggle to penetrate.
Treatment Regimens:
Can be given continuously (e.g., 200 mg twice daily for 6–12 weeks) or as pulse therapy (e.g., 200 mg twice daily for 1 week per month, repeated for several months).
Pulse therapy can reduce side effects and improve adherence.
In brief: Itraconazole works by inhibiting ergosterol synthesis in fungal cell membranes, weakening and killing the fungi causing onychomycosis. Its good nail penetration via oral dosing makes it effective for treating fungal nail infections.
Terbinafine plays a central role in managing onychomycosis (fungal nail infection) due to its effectiveness and relatively favorable safety profile. Here’s a detailed overview of its role:
Role of Terbinafine in Onychomycosis Management
1. Mechanism of Action
Terbinafine is an oral antifungal that inhibits the enzyme squalene epoxidase in fungal cells.
This inhibition disrupts fungal cell membrane synthesis, leading to fungal cell death (fungicidal effect).
2. Effectiveness
Highly effective against dermatophytes, the most common cause of onychomycosis.
Usually prescribed as a 12-week oral treatment for fingernail infections and up to 16 weeks for toenail infections.
Demonstrates higher cure rates compared to some other antifungals.
3. Advantages
Fungicidal action leads to faster and more complete eradication of the fungus.
Generally well tolerated with fewer drug interactions than some other antifungals.
Good nail penetration, reaching the site of infection effectively.
4. Treatment Considerations
Requires liver function monitoring before and during treatment, especially for patients with liver issues.
Side effects may include gastrointestinal symptoms, taste disturbances, and rare liver toxicity.
Patients should be advised to complete the full course for best results, even if symptoms improve early.
5. Use in Combination
Sometimes combined with topical antifungals or nail debridement to enhance effectiveness.
