Amoxicillin-clavulanate potassium（Cat No.:R037133）is a broad-spectrum beta-lactam/beta-lactamase inhibitor combination antibiotic, composed of amoxicillin, a penicillin-class antibiotic, and clavulanate potassium, a beta-lactamase inhibitor. Amoxicillin inhibits bacterial cell wall synthesis, while clavulanate blocks beta-lactamase enzymes that confer resistance, thereby extending the drug’s efficacy against beta-lactamase–producing bacteria. This combination is widely used to treat respiratory tract infections, urinary tract infections, skin infections, and sinusitis caused by Gram-positive and Gram-negative pathogens. It is available in both oral and intravenous formulations, offering broad clinical utility and a well-established safety profile in community and hospital settings.
