Medicine Description unasyn-injection 375mg
Unasyn Injection is a medication that combines ampicillin, a penicillin-type antibiotic, with sulbactam, a beta-lactamase inhibitor. The mechanism of action begins with ampicillin inhibiting bacterial cell wall synthesis, leading to cell lysis and death. This action is effective against a broad spectrum of gram-positive and some gram-negative bacteria. Sulbactam serves to protect ampicillin from degradation by beta-lactamase enzymes produced by certain bacteria. By inhibiting these enzymes, sulbactam enhances the efficacy of ampicillin, allowing it to effectively target bacteria that would otherwise be resistant due to beta-lactamase production.
