Amoxicillin/clavulanic acid
（重定向自Coamoxiclav）
Amoxicillin/clavulanic acid or co-amoxiclav is an antibiotic useful for the treatment of a number of bacterial infections. It is a combination antibiotic consisting of amoxicillin trihydrate, a β-lactam antibiotic, and potassium clavulanate, a β-lactamase inhibitor. This combination results in an antibiotic with an increased spectrum of action and restored efficacy against amoxicillin-resistant bacteria that produce β-lactamase.
