β-Lactam antibiotics are bactericidal agents that interrupt bacterial cell-wall formation as a result of covalent binding to essential penicillin-binding proteins (PBPs), enzymes that are involved in the terminal steps of peptidoglycan cross-linking in both Gram-negative and Gram-positive bacteria. Antibiotics are listed alphabetically within their class or subclass by their nonproprietary name. If an antibiotic is a combination drug , both ingredients will be listed. The β-lactam core structures. Medical use. β-lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms.

Since the discovery of benzylpenicillin in the 1920s, thousands of new penicillin derivatives and related β-lactam classes of cephalosporins, cephamycins, monobactams, and carbapenems have been discovered. Beta-Lactam Antibiotics and Vancomycin Beta-lactam antibiotics Penicillins Cephalosporins Carbapenems Monobactams I. General principles of antibiotic activity: Anti-bacterial drugs have “selective toxicity”, that is they interact with a target present on the bacterial cell, What are carbapenems • Carbapenems are a class of beta-lactam antibiotics with a broad spectrum of antibacterial activity. They have a structure that renders them highly resistant to beta- lactamases.

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.
