For tinea barbae, which systemic antifungal agent is listed as a treatment option?

• A. Terbinafine
• B. Fluconazole
• C. Itraconazole
• D. Griseofulvin

Answer: (D)

Griseofulvin is listed because tinea barbae affects beard hair, and this drug has a distinctive ability to become incorporated into keratin as it is formed in growing skin, hair, and nails. That means the antifungal activity is delivered right into the structures that are being formed, including the beard hairs, which is especially important for infections involving hair. Griseofulvin works by disrupting fungal cell division through interaction with fungal microtubules, effectively halting the dermatophyte’s growth as new keratin is produced. Because beard hair and other keratinized tissues take time to replace, treatment must be prolonged and patient monitoring is advised for liver function and drug interactions. While newer options like terbinafine and itraconazole are common today for many dermatophyte infections, griseofulvin remains a classic systemic choice for tinea barbae, reflecting its proven penetration into hair-bearing skin.
