Amoxicillin clavulanic
Amoxicillin-clavulanic acid is a combination antibiotic that kills bacteria by inhibiting cell wall synthesis, with clavulanic acid protecting amoxicillin from enzymatic degradation by beta-lactamases.
Amoxicillin-clavulanic acid is a combination antibiotic that kills bacteria by inhibiting cell wall synthesis, with clavulanic acid protecting amoxicillin from enzymatic degradation by beta-lactamases. Used for Bacterial infections caused by beta-lactamase-producing organisms (respiratory tract infections, urinary tract infections, skin and soft tissue infections, otitis media), Helicobacter pylori eradication (as part of combination therapy).

Mechanism of action
Amoxicillin is a beta-lactam antibiotic that binds to penicillin-binding proteins and inhibits bacterial cell wall cross-linking, leading to cell lysis and death. Clavulanic acid is a beta-lactamase inhibitor that irreversibly binds to and inactivates bacterial beta-lactamases, enzymes that would otherwise destroy amoxicillin. This combination extends amoxicillin's spectrum to include beta-lactamase-producing organisms.
