The main idea is that combining a beta-lactam antibiotic with a beta-lactamase inhibitor widens its activity by protecting the antibiotic from bacterial enzymes that would otherwise inactivate it. In Augmentin, the inhibitor is clavulanate. Clavulanate acts as a mechanism-based inhibitor, binding to and inactivating many beta-lactamases produced by resistant bacteria. This shields amoxicillin, allowing it to retain activity against organisms that make these enzymes, so you get effectiveness against beta-lactamase–producing strains that would resist amoxicillin alone. Other beta-lactamase inhibitors exist in different antibiotic combinations, but for Augmentin the pairing is amoxicillin with clavulanate.
