Clavulanate potassium 

Clavulanate potassium is a potent β-lactamase inhibitor and acts as an antibiotic^[1][2].

Clavulanate potassium has weak antibacterial activity against most organisms when administered alone, but given in combination with beta-lactam antibiotics prevents antibiotic inactivation by microbial lactamase^[1].
Clavulanate potassium (0.25 mg/L, 0.5 mg/L) causes a relatively slow inhibition of growth, and a higher concentration (1 mg/L) is only marginally more effective than 0.5 mg/L^[2].
