• Drug Groups: approved
• 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.
• Toxicity: Gastrointestinal symptoms including stomach and abdominal pain, vomiting, and diarrhea. Rash, hyperactivity, or drowsiness have also been observed in a small number of patients
• Affected Organisms: Enteric bacteria and other eubacteria
• Biotransformation: Hepatic
• Absorption: 75%
• Half Life: 1.0 hour
• Protein Binding: Low (22 to 30%)
