what is the difference between erythromycin and augmentin?
Erythromycin is a macrolide antibacterial with a spectrum similar, however not identical to penicillin. Erythromycin is therefore commonly used in penicillin-allergic patients. Co-amoxiclav (brand name Augmentin) is a combination of amoxicillin, broad-spectrum penicillin and clavulanic acid, a beta lactamase inhibitor.
