Content: The Powder for Injection contains either 1 g ampicillin sodium and 0.5 g sulbactam sodium or 2 g ampicillin sodium and 1 g sulbactam sodium.

Action/Kinetics: For details, see Ampicillin oral. Sulbactam is present in this product because it irreversibly inhibits beta-lactamases, thus ensuring activity of ampicillin against beta-lactamase-producing microorganisms. Thus, sulbactam broadens the antibiotic spectrum of ampicillin to those bacteria normally resistant to it. Peak serum levels, after IV infusion: 15 min. tv2, both drugs: about 1 hr. From 75%-85% of both drugs is excreted unchanged in the urine within 8 hr after administration.

NOTE: Mixed infections caused by ampicillin-susceptible organisms and beta-lactamase-produc-ing organisms are susceptible to this product; thus, additional antibiotics do not have to be used.
