 (tā′zō-băk′tăm)
n.
A compound, C10H12N4O5S, that inhibits action of the enzyme beta-lactamase, thus counteracting bacterial resistance to beta-lactam antibiotics. It is used in its sodium form in combination with piperacillin to treat infections caused by antibiotic-resistant bacteria.

[Probably t(ri)- + azo- + -bactam, suffix for inhibitors of beta-lactamase, bacterial enzyme conferring resistance to certain antibiotics (b(eta)- + lactamase).]
