| '''Ampicillin/sulbactam''' is a combination of the common [[penicillin]]-derived [[antibiotic]] [[ampicillin]] and [[sulbactam]], an [[Enzyme inhibitor|inhibitor]] of [[bacteria]]l [[beta-lactamase]]. Two different forms of the drug exist. The first, developed in [[1987]] and marketed in the United States under the tradename '''Unasyn''', is an [[intravenous]] antibiotic. The second, an oral form called [[sultamicillin]], is marketed under the trade name '''Ampictam''' outside of the United States. Ampicillin/sulbactam is used to treat [[infection]]s caused by bacteria resistant to [[beta-lactam antibiotic]]s. Sulbactam blocks the [[enzyme]] which breaks down ampicillin and thereby allows ampicillin to attack and kill the bacteria.

| Ampicillin/sulbactam is also used when the cause of an infection is not known ([[empiric therapy]]). [[peritonitis|Intra-abdominal infections]], skin infections, [[pneumonia]], and [[gynecology|gynecologic infections]]. It is active against a wide range of bacterial groups, including ''[[Staphylococcus aureus]]'', ''[[Enterobacteriaceae]]'', and [[anaerobic bacteria]]. Importantly, it is not active against ''[[Pseudomonas aeruginosa]]'' and should not be used alone when infection with this organism is suspected or known.
