Amoxicillin is a semi-synthetic antibiotic with a broad spectrum of bactericidal activity against many gram-positive and gram-negative microorganisms. Amoxicillin inhibits cell wall synthesis leading to lysis of the bacterial cell. Amoxicillin is, however, susceptible to degradation by β-lactamases, and therefore, the spectrum of activity does not include organisms which produce these enzymes. Clavulanic acid is a β-lactamase inhibitor which possesses the ability to inactivate a wide range of β-lactamase enzymes commonly found in microorganisms resistant to penicillin and cephalosporins. In particular, it has good activity against clinically important plasmid mediated β-lactamases frequently responsible for drug resistance.

The most frequently reported adverse effects were diarrhea/loose stools, nausea, skin rashes and urticaria, vomiting and vaginitis. Other less frequently reported reactions include: Abdominal discomfort, flatulence, and headache.
