Ampicillin sodium and Sulbactam sodium

Ampicillin sodium and Sulbactam sodium are formed by mixing Ampicillin sodium with Sulbactam sodium (each 1.5 g of this product contains 1 g amoxicillin sodium and 0.5 g sulbactam sodium). Ampicillin is a β-lactam antimicrobial, whereas sulbactam is a β-lactamase inhibitor. Ampicillin has a broad spectrum of bactericidal activity against many gram-positive and gram-negative aerobic and anaerobic bacteria. However, ampicillin is degraded by beta-lactamases. The combination of ampicillin and sulbactam demonstrates synergy in addressing bacterial strains resistant to ampicillin, thus providing broader coverage. Bacteria susceptible to ampicillin/sulbactam include Haemophilus influenzae, Escherichia coli, Acinetobacter, Klebsiella, Staphylococcus aureus, Enterobacter, and anaerobes.
