- Mechanism of action
Sulbactam is an irreversible inhibitor of β-lactamase; by binding and inhibiting β-lactamase produced by bacterial cells, sulbactam is thereby able to prevent it from reducing antibiotic activity. Although sulbactam alone possesses little useful antibacterial activity, except against the Neisseriaceae, whole organism studies have shown that sulbactam restores ampicillin activity against beta-lactamase producing strains. In particular, sulbactam has good inhibitory activity against the clinically important plasmid mediated beta-lactamases most frequently responsible for transferred drug resistance. The presence of sulbactam in formulations with ampicillin effectively extends the antibacterial spectrum of ampicillin to include many bacteria normally resistant to it and to other beta-lactam antibacterials. Thus, products with ampicillin + sulbactam possess the properties of a broad-spectrum antibacterial and a beta-lactamase inhibitor.
Target Actions Organism ABeta-lactamase inhibitorStaphylococcus aureus - Absorption
Peak serum concentrations are reached almost immediately following a 15-minute intravenous infusion of sulbactam + ampicillin. Mean peak serum levels for sulbactam range from 48 to 88 mcg/mL following intravenous administration of 2000 mg of ampicillin plus 1000 mg sulbactam. After an intramuscular injection of 1000 mg ampicillin plus 500 mg sulbactam, peak sulbactam serum levels ranging from 6 to 24 mcg/mL are attained.
- Volume of distribution
Penetration of both ampicillin and sulbactam into cerebrospinal fluid in the presence of inflamed meninges has been demonstrated after IV administration.
- Protein binding
Approximately 38% reversibly bound to human serum protein.
- Metabolism
- Not Available
- Route of elimination
Approximately 75 to 85% of both ampicillin and sulbactam are excreted unchanged in the urine during the first 8 hours after administration.

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Abacavir may decrease the excretion rate of Sulbactam which could result in a higher serum level. Aceclofenac Aceclofenac may decrease the excretion rate of Sulbactam which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Sulbactam which could result in a higher serum level. Acetaminophen Acetaminophen may decrease the excretion rate of Sulbactam which could result in a higher serum level. Acetazolamide Acetazolamide may increase the excretion rate of Sulbactam which could result in a lower serum level and potentially a reduction in efficacy. Acetylsalicylic acid Acetylsalicylic acid may decrease the excretion rate of Sulbactam which could result in a higher serum level. Aclidinium Aclidinium may decrease the excretion rate of Sulbactam which could result in a higher serum level. Acrivastine Sulbactam may decrease the excretion rate of Acrivastine which could result in a higher serum level. Acyclovir Acyclovir may decrease the excretion rate of Sulbactam which could result in a higher serum level. Adefovir dipivoxil Adefovir dipivoxil may decrease the excretion rate of Sulbactam which could result in a higher serum level.
