Introduction
Ampicillin sodium and sulbactam sodium, a combination of a β-lactam antibiotic and a β-lactamase inhibitor, is a potent antibacterial agent used in various clinical settings. This article delves into the clinical trials, market analysis, and projections for this drug combination.
Mechanism of Action and Spectrum
Ampicillin sodium works by interfering with the activity of penicillin-binding proteins (PBPs), which are essential for the synthesis of the bacterial cell wall. Sulbactam sodium, as a β-lactamase inhibitor, enhances the efficacy of ampicillin by inhibiting β-lactamases produced by bacteria, thereby extending the antibacterial spectrum to include bacteria that would otherwise be resistant to ampicillin alone[1][3][5].
Clinical Trials and Efficacy
Clinical trials have consistently shown the efficacy of ampicillin/sulbactam in treating a wide range of bacterial infections. These trials have demonstrated the combination's effectiveness against Gram-negative and Gram-positive bacteria, including medically important enteric pathogens such as Shigella and Salmonella, as well as certain strains of vancomycin-resistant Enterococcus[1][3].
Key Findings
- Infectious Disease Treatment: Studies have highlighted the combination's ability to treat severe infections, including those caused by β-lactamase-producing bacteria.
- Pharmacokinetics: Clinical trials have shown that the combination achieves peak serum concentrations quickly, with a mean serum half-life of approximately 1 hour in healthy volunteers[3].

Applications and Uses
Microbiology Applications
Ampicillin/sulbactam is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests, including panels, discs, and MIC strips, to determine the susceptibility of bacterial isolates to this antibiotic combination[1].
Eukaryotic Cell Culture Applications
Ampicillin is also used in eukaryotic cell culture to select for cells containing specific resistance plasmids, such as pcDNA3.1 and pEAK10[1].
Dosage and Administration
The recommended adult dosage of ampicillin/sulbactam ranges from 1.5 g to 3 g every six hours, with the total dose of sulbactam not exceeding 4 grams per day. The combination is available for intravenous and intramuscular administration[3][5].
Safety and Adverse Reactions
While generally well-tolerated, ampicillin/sulbactam can cause adverse reactions, including neurological effects such as convulsions, especially at high CSF levels. Both ampicillin and sulbactam can be removed by hemodialysis[3].
Conclusion
Ampicillin sodium and sulbactam sodium represent a crucial combination in the fight against bacterial infections, particularly those caused by β-lactamase-producing bacteria. With a strong market presence and projected growth, this combination is set to remain a vital tool in clinical settings.
