Clavulanate lithium is a potent β-lactamase inhibitor and acts as an antibiotic[1][2].
Clavulanate lithium 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 lithium (0.25, 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]. Cell Viability Assay[2] Cell Line: L. pneumophila NCTC 1119
