Amoxicillin-Clavulanate is a combination antibiotic used to treat a wide range of bacterial infections. It contains amoxicillin, a penicillin-type antibiotic that kills bacteria, and clavulanate potassium, a beta-lactamase inhibitor that helps prevent certain bacteria from resisting the antibiotic. This combination enhances the effectiveness of treatment against bacteria that would otherwise be resistant to amoxicillin alone. It is commonly prescribed for infections of the respiratory tract, urinary tract, skin, and sinuses.
