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.

The principal antibiotic families of which the β-lactam ring is part of the core structure are the penicillins, cephalosporins, carbapenems, and monobactams, which are also called β-lactam antibiotics. A β-lactam (beta-lactam) ring is a four-membered lactam (cyclic amide).

B lactam antibiotics

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.

Beta-lactamases are enzymes produced by bacteria that break open the beta-lactam ring, inactivating the beta-lactam antibiotic. Some beta-lactamases are encoded on mobile genetic elements (eg, plasmids); others are encoded on chromosomes. There are numerous different types of beta-lactamases.

The β-lactam antibiotics—penicillins, cephalosporins, carbapenems, and monobactams—share a common structure (β-lactam ring) and mechanism of action (i.e., inhibition of the synthesis of the bacterial peptidoglycan cell wall). Diagnosis of nonimmediate reactions to b-lactam antibiotics b-Lactams, particularly penicillins, may cause several kinds of allergic reactions, which have been classified as immediate, accelerated, or delayed according to the time interval between the last drug administration and their onset (1). This terminology may be simplified by classi- The discovery and development of the beta–lactam antibiotics is the most powerful, important and famous achievement of modern science and technology.
