Cefuroxime; Indications/Uses, Dosage, Side Effects, Interactions

Cefuroxime is a semisynthetic, broad-spectrum, beta-lactamase-resistant, second-generation cephalosporin with antibacterial activity. Cefuroxime binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that cefuroxime interferes with an autolysin inhibitor. This effect is bactericidal.

Mechanism of Action of Cefuroxime

Cefuroxime, like the penicillins, is a beta-lactam antibiotic. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that cefuroxime interferes with an autolysin inhibitor.

Cefuroxime, a beta-lactam antibiotic similar to penicillins, inhibits the third and final stage of bacterial cell wall synthesis by preferentially binding to specific penicillin-binding proteins (PBPs) that are located inside the bacterial cell wall. Penicillin-binding proteins are responsible for several steps in the synthesis of the cell wall and are found in quantities of several hundred to several thousand molecules per bacterial cell. Penicillin-binding proteins vary among different bacterial species. Thus, the intrinsic activity of cefuroxime, as well as the other cephalosporins and penicillins against a particular organism, depends on their ability to gain access to and bind with the necessary PBP. Like all beta-lactam antibiotics, cefuroxime’s ability to interfere with PBP-mediated cell wall synthesis ultimately leads to cell lysis. Lysis is mediated by bacterial cell wall autolytic enzymes (i.e., autolysins). The relationship between PBPs and autolysins is unclear, but it is possible that the beta-lactam antibiotic interferes with an autolysin inhibitor. Cefuroxime possesses activity against both Gram-positive and Gram-negative bacteria. The drug retains antibacterial activity in the presence of certain beta-lactamases, both penicillinase, and cephalosporins; however hydrolysis by other beta-lactamases, alteration of the PBP, and decreases permeability results in resistance to cefuroxime.
