Value:Cell wall synthesis inhibitor

Antibacterial mechanism

Primarily used for uncomplicated urinary tract infections caused by susceptible gram-negative bacteria, particularly Enterobacteriaceae. May also be used for other infections as determined by a healthcare provider based on susceptibility testing.

As a beta-lactam antibiotic, it inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), which are essential for cross-linking peptidoglycan in the bacterial cell wall. Without a intact cell wall, bacteria cannot maintain structural integrity and eventually die.

Patients with known penicillin allergy should avoid this medication. Common side effects may include gastrointestinal symptoms such as nausea and diarrhea. Complete the full prescribed course even if symptoms improve to prevent antibiotic resistance. Always use under medical supervision with appropriate diagnostic confirmation of bacterial infection.
