Amoxicillin/Clavulanate Potassium Tablets are a broad-spectrum antibiotic for treatment of bacterial infections. Amoxicillin/Clavulanate Potassium Tablets combine amoxicillin, a synthetic penicillin-type antibiotic, with clavulanate potassium, a beta-lactamase inhibitor to protect the antibiotic from certain enzymes that may destroy the amoxicillin.
