Nevertheless, the risk of cross-reactivity is sufficient to warrant the contraindication of all β-lactam antibiotics in patients with a history of severe allergic reactions (urticaria, anaphylaxis, interstitial nephritis) to any β-lactam antibiotic. Rarely, allergic reactions have been triggered by exposure from kissing and sexual contact ...
The β-lactam core structures. (A) A penam.(B) A carbapenam.(C) An oxapenam.(D) A penem.(E) A carbapenem.(F) A monobactam.(G) A cephem.(H) A carbacephem.(I) An oxacephem. This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class.
Meropenem, sold under the brand name Merrem among others, is an intravenous carbapenem antibiotic used to treat a variety of bacterial infections. [3] Some of these include meningitis, intra-abdominal infection, pneumonia, sepsis, and anthrax.
The simplest β-lactam possible is 2-azetidinone. β-lactams are significant structural units of medicines as manifested in many β-lactam antibiotics. [2] Up to 1970, most β-lactam research was concerned with the penicillin and cephalosporin groups, but since then, a wide variety of structures have been described. [3] [4]
The commonly quoted figure of 10% of patients with allergic hypersensitivity to penicillins and/or carbapenems also having cross-reactivity with cephalosporins originated from a 1975 study looking at the original cephalosporins, [9] and subsequent "safety first" policy meant this was widely quoted and assumed to apply to all members of the ...
Benzylpenicillin, a penicillin. The double bond is absent in the pentacyclic ring. The double bond is absent in the pentacyclic ring. Penem molecules do not occur naturally, and production of penems is an entirely synthetic process.
Monobactam antibiotics exhibit no IgE cross-reactivity reactions with penicillin but have shown some cross reactivity with cephalosporins, most notably ceftazidime, which contains an identical side chain as aztreonam. [9] Monobactams can trigger seizures in patients with history of seizures, although the risk is lower than with penicillins.
The Meropenem Yearly Susceptibility Test Information Collection Program noted that resistance within K. pneumoniae alone increased from 0.6% in 2004 to 5.6% in 2008. [10] The first outbreak involving colistin-resistant, carbapenem-resistant K. pneumoniae (CRKP) in the U.S. was discovered in Detroit , Michigan in 2009, involving three different ...
