ZOSYN is a fixed-dose combination of piperacillin (a broad-spectrum beta-lactam antibiotic) and tazobactam (a beta-lactamase inhibitor) administered by injection. It treats serious infections including complicated appendicitis, peritonitis, nosocomial pneumonia, skin/skin structure infections, and pelvic inflammatory disease caused by beta-lactamase producing gram-negative and gram-positive organisms. The tazobactam component protects piperacillin from enzymatic degradation, extending its spectrum against resistant bacteria.
