Description and Uses

Clavulanate is a β-lactamase inhibitor that is effective against Ambler class A β-lactamases (IC₅₀ values range from 12 to 60 nM). While it is not an effective antibiotic by itself, clavulanate is commonly used with other antibiotics that would be inactivated by β-lactamases secreted by bacteria. It is often combined with amoxicillin and other penicillin-based antibiotics.

Clavulanic acid is a β-lactam antibiotic produced by several species of Streptomyces. The free acid degrades and is isolated and maintained as either the sodium or potassium salt. Clavulanate is a weak antibiotic, but is a potent inhibitor of β-lactamases. In combination with penicillin and cephalosporins, it shows potent synergistic activity. Clavulanic acid is a suicide inhibitor, covalently binding to a serine residue in the active site of the β-lactamase.
