Clavamox is a broad-spectrum antibiotic containing amoxicillin trihydrate and clavulanate potassium. This combination makes for a highly effective antibiotic, as the clavulanate potassium increases the amount of time the antibiotic stays actively working in the body. The clavulanate potassium acts to inhibit the ß-lactamase, an enzyme which typically inactivates many other antibiotics. Once the ß-lactamase enzyme is restrained, the amoxicillin works to destroy harmful bacteria cells.
