ESBL stands for Extended-Spectrum beta-Lactamase. Beta lactamases are enzymes that are produced by many types of bacteria (germs) which make them more resistant to antibiotics and can make the infection harder to treat.
Î²-lactam antibiotics (beta-lactam antibiotics) are a broad class of antibiotics, consisting of all antibiotic agents that contain a Î²-lactam ring in their molecular structures.This includes penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems.Most Î²-lactam antibiotics work by inhibiting cell wall biosynthesis in the bacterial organism and are the most widely used group of antibiotics.ommon adverse drug reactions (ADRs) for the Î²-lactam antibiotics include diarrhea, nausea, rash, urticaria, superinfection (including candidiasis). Infrequent ADRs include fever, vomiting, erythema, dermatitis, angioedema, pseudomembranous colitis.
