These are beta-lactam antibiotics that inhibit bacterial cell wall synthesis by binding to penicillin-binding proteins, leading to cell wall rupture and bacterial death.

These are beta-lactam antibiotics that inhibit bacterial cell wall synthesis by binding to penicillin-binding proteins, leading to cell wall rupture and bacterial death. Used for Bacterial infections including pneumonia, intra-abdominal infections, urinary tract infections, and sepsis, Hospital-acquired and community-acquired infections caused by susceptible gram-positive and gram-negative organisms.

Mechanism of action

Cefepime is a fourth-generation cephalosporin, Meropenem is a broad-spectrum carbapenem, and Piperacillin/Tazobactam is a beta-lactam/beta-lactamase inhibitor combination. All three work by disrupting peptidoglycan cross-linking in the bacterial cell wall. Piperacillin/Tazobactam includes tazobactam, a beta-lactamase inhibitor that protects piperacillin from enzymatic degradation by resistant bacteria.
