Indication |
For use with Amoxicillin, clavulanic acid is suitable for the treatment of infections with Staph. aureus and Bacteroides fragilis, or with beta-lactamase producing H. influenzae and E. coli. |
Pharmacodynamics |
Clavulanic acid, produced by the fermentation of Streptomyces Clavuligerus,
is a beta-lactam structurally related to the penicillins. Clavulanic
acid is used in conjunction with amoxicillin for the treatment of
bronchitis and urinary tract, skin, and soft tissue infections caused by
beta-lactamase producing organisms. |
Mechanism of action |
Clavulanic acid competitively and irreversibly inhibits a wide
variety of beta-lactamases, commonly found in microorganisms resistant
to penicillins and cephalosporins. Binding and irreversibly inhibiting
the beta-lactamase results in a restauration of the antimicrobial
activity of beta-lactam antibiotics against
lactamase-secreting-resistant bacteria. By inactivating beta-lactamase
(the bacterial resistance protein), the accompanying
penicillin/cephalosporin drugs may be made more potent as well. |
