How Onychomycosis Medications Work

Onychomycosis is a fungal infection of the nail, caused by various types of fungi. The gold standard treatment for onychomycosis is Terbinafine, an antifungal medication that works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes.

Gold Standard: Terbinafine

• Terbinafine is absorbed through the skin and reaches effective concentrations in the nail plate, where it exerts its antifungal effects.
• It selectively targets fungal cells, causing cell death and preventing further growth of the fungus.
• The medication is usually taken orally for several months to ensure complete clearance of the infection.

Alternatives and Adjuncts

For patients who cannot tolerate Terbinafine or have failed treatment, alternative antifungal medications such as Itraconazole and Fluconazole may be considered. In some cases, surgical excision of the affected nail may also be an option.

Key Considerations

• Diagnosis is crucial to ensure accurate treatment; diagnostic tests include KOH prep, dermatophyte culture, and histopathology.
• Patient compliance and adherence to treatment regimens are essential for successful outcomes.
• Risk factors such as age > 60 years, diabetes mellitus, and immunocompromised state should be taken into account when selecting a treatment plan.
