AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
ZOSYN is a fixed-dose combination of piperacillin (a beta-lactam antibiotic) and tazobactam (a beta-lactamase inhibitor) administered by injection. It treats serious infections including nosocomial pneumonia, complicated intra-abdominal infections, skin infections, and pelvic inflammatory disease caused by beta-lactamase-producing gram-negative and gram-positive organisms. The tazobactam component protects piperacillin from enzymatic degradation, broadening its spectrum against resistant pathogens.
