Area of Science:

  • Dermatology
  • Mycology
  • Pharmacology

Background:

  • Onychomycosis is a prevalent fungal nail infection impacting patient quality of life.
  • It affects up to 30% of individuals by age 60, primarily caused by dermatophytes.
  • Differential diagnosis is crucial as other conditions like psoriasis can mimic onychomycosis.

Purpose of the Study:

  • To review the management of onychomycosis.
  • To compare traditional treatments with newer oral antifungal agents.
  • To highlight the efficacy of oral terbinafine.

Main Methods:

  • Review of existing literature on onychomycosis treatments.
  • Analysis of pharmacologic properties and clinical outcomes of antifungal drugs.
  • Emphasis on diagnostic confirmation through potassium hydroxide (KOH) slide preparation and culture.

Main Results:

  • Traditional treatments, like griseofulvin, have suboptimal cure rates and long treatment durations.
  • Newer agents, including oral itraconazole and terbinafine, demonstrate improved efficacy and shorter treatment periods.
  • Oral terbinafine shows potent fungicidal activity against dermatophytes, with effective regimens as short as 12 weeks.

Conclusions:

  • Accurate diagnosis is essential for effective onychomycosis management.
  • Oral terbinafine represents a significant advancement in treating onychomycosis, offering higher cure rates and reduced treatment time.
  • The shift towards more potent and targeted antifungal therapies improves patient outcomes and quality of life.
