Erythromycin is classified as what type of medication?

Erythromycin is classified as an antibiotic, which is a type of medication used to combat bacterial infections. The correct classification, in this case, is antibiotic ointment, as erythromycin can be formulated in an ointment form for topical application, especially for treating skin infections or conditions caused by bacteria. This formulation allows the medication to be applied directly to the affected area, providing localized treatment with effective antibacterial action.

While erythromycin is also available in tablet, suspension, and eye drop forms, these specific options pertain to different applications of the drug. The ointment form is particularly used when treating localized infections, making it a suitable choice in certain clinical scenarios.
