Sulbactam

Sulbactam Uses, Dosage, Side Effects, Food Interaction and all others data.

Sulbactam is a β-lactamase inhibitor given in combination with β-lactam antibiotics to inhibit β-lactamase, an enzyme produced by bacteria that destroys antibiotic activity.

Uses

Sulbactam is an beta-lactamase inhibitor antibiotic combined with other antibiotics to treat a variety of susceptible bacterial infections.

Sulbactam is currently available in combination products with ampicillin. Within this formulation it is indicated for the treatment of infections due to susceptible strains of the designated microorganisms in the conditions listed below. Skin and Skin Structure Infections caused by beta-lactamase producing strains of Staphylococcus aureus, Escherichia coli, Klebsiella spp. (including K. pneumoniae), Proteus mirabilis, Bacteroides fragilis, Enterobacter spp., and Acinetobacter calcoaceticus. Intra-Abdominal Infections caused by beta-lactamase producing strains of Escherichia coli, Klebsiella spp. (including K. pneumoniae), Bacteroides spp. (including B. fragilis), and Enterobacter spp. Gynecological Infections caused by beta-lactamase producing strains of Escherichia coli, and Bacteroides spp. (including B. fragilis).

Sulbactam is also used to associated treatment for these conditions: Animal bite, Bacterial Infections, Bacterial Infections caused by Beta lactamase producing bacteria, Bacterial Sinusitis, Bites, Human, Catheter Related Infections, Community Acquired Pneumonia (CAP), Gynaecological infection, Infective Endocarditis, Intra-Abdominal Infections, Nosocomial Pneumonia, Postoperative Infections, Postoperative Wound Infection, Skin and Subcutaneous Tissue Bacterial Infections, Complicated Bacterial Infections caused by Beta lactamase producing bacteria, Moderate Bacterial Infections, Severe Bacterial Infections

How Sulbactam works

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.

Food Interaction

No interactions found.

Volume of Distribution

Penetration of both ampicillin and sulbactam into cerebrospinal fluid in the presence of inflamed meninges has been demonstrated after IV administration.

Elimination Route

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.
