#140 – Beta-lactamase inhibitors: “Scientifically elegant, just complex"

Author: Society of Infectious Diseases Pharmacists August 21, 2026 Duration: 1:16:18

Gram-negative resistance is beautifully intricate, scientifically elegant, and very complex. Nothing is more exciting than the recently approved and bursting pipeline of beta-lactamase inhibitors. Listen to Drs. Sam Aitken and Christophe Le Terrier, along with host Dr. Erin McCreary, describe the nuanced enzymology and other antibacterial properties of beta-lactamase inhibitors. This episode also discusses the concepts of stand-alone inhibitors, resistance development, and more. If you want to learn more about sulbactam, clavulanic acid, tazobactam, avibactam, relebactam, vaborbactam, durlobactam, enmetazobactam, zidebactam, nacubactam, ledaborbactam, taniborbactam, and xeruborbactam – this episode is for you!
