Which antibiotic is commonly prescribed for a corneal abrasion?

The commonly prescribed antibiotic for a corneal abrasion is gentamicin ophthalmic solution. This medication is part of the aminoglycoside class of antibiotics and is specifically formulated for ocular use. It is effective against a broad spectrum of bacteria, especially those that are commonly responsible for eye infections. Corneal abrasions can lead to complications, such as infections, so prompt and effective treatment is crucial. Gentamicin ophthalmic solution can help reduce the risk of developing secondary infections from the abrasion.

While other antibiotics listed may have clinical uses in treating various infections, they are not typically the first choice for corneal abrasions. Amoxicillin is primarily effective for systemic infections and not formulated for ocular use. Ciprofloxacin, although it's effective against a range of ocular bacteria, is generally more appropriate for specific bacterial keratitis rather than straightforward abrasions. Vancomycin, too, is usually reserved for more serious infections known to be resistant and is not a primary treatment for corneal abrasions. Thus, gentamicin is preferred in this context due to its efficacy and suitability for direct application to the eye.
