After oral administration of sulbactam pivoxil, the ester bond is cleaved, releasing active sulbactam. The beta-lactam ring of sulbactam irreversibly binds to beta-lactamase at or near its active site, thereby blocking enzyme activity and preventing metabolism of other beta-lactam antibiotics by the enzyme."}]
