There are numerous different types of beta-lactamases. Some antimicrobials (eg, cefazolin and cloxacillin) are naturally resistant to certain beta-lactamases. The activity of the beta-lactams: amoxicillin, ampicillin, piperacillin, and ticarcillin, can be restored and widened by combining them with a beta-lactamase inhibitor. Clavulanic acid, sulbactam, and tazobactam are all beta-lactamase inhibitors. beta-lactams have a long history in the treatment of infectious diseases, though their use has been and continues to be confounded by the development of resistance in target organisms.

Betalaktamresistens Svensk MeSH

Het meest bekende β-lactam antibioticum is penicilline. Ist eine höhere Konzentration von Beta-Laktam-Antibiotikum vorhanden, wird auch das Enzym vermehrt gebildet. Um diese Resistenzentwicklung zu überlisten sind Hemmstoffe der Beta-Laktamase (z.B. Clavulansäure) entwickelt worden, die bei gleichzeitiger Gabe mit dem Antibiotikum dessen Wirksamkeit erhöhen.
