Metronidazole (MetroGel) is primarily used to treat ___________.

• A. Dry eye syndrome
• B. Corneal ulcers
• C. Acne rosacea
• D. Hyperlipidemia

Answer: (C)

Topical metronidazole is used for acne rosacea because it helps calm the facial skin by reducing inflammation and the inflammatory papules and pustules that characterize rosacea. MetroGel targets the inflammatory component of rosacea, which is why it’s a common topical therapy for this condition.

It isn’t used for dry eye syndrome, which is managed with lubricants or other eye-specific therapies; corneal ulcers require different topical antibiotics or antifungals tailored to eye infections; and hyperlipidemia is treated with lipid-lowering medications. So acne rosacea is the appropriate indication for MetroGel.
