Description
|
Clavulanic acid and its salts and esters. The acid is a suicide inhibitor of bacterial beta-lactamase enzymes from Streptomyces clavuligerus. Administered alone, it has only weak antibacterial activity against most organisms, but given in combination with beta-lactam antibiotics prevents antibiotic inactivation by microbial lactamase. [PubChem] |
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. |
Pharmacology |
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. |
