BLI-489 hydrate, a penem β-lactamase inhibitor, is active against class A and class C as well as some class D β-lactamases. The combination of Piperacillin and BLI-489 hydrate is efficacious against murine infections caused by class A (including extended-spectrum β-lactamases), class C (AmpC), and class D β-lactamase-expressing pathogens[1][2].
On the basis of preliminary results with various ratios, a dosing ratio of 8:1 was found to be optimal for retention of enhanced efficacy. Piperacillin-BLI-489 dosed at an 8:1 ratio was efficacious against murine infections caused by class A (including extended-spectrum beta-lactamases), class C (AmpC), and class D beta-lactamase-expressing pathogens[2].
