Bulk Active Pharmaceutical Ingredient (API) Sources for ZOSYN

Last updated: July 28, 2025

Introduction

ZOSYN, the brand name for piperacillin-tazobactam, combines a broad-spectrum penicillin antibiotic with a β-lactamase inhibitor to combat resistant bacterial strains. Widely prescribed for serious infections, ZOSYN’s efficacy hinges on the quality, purity, and consistent supply of its active pharmaceutical ingredients (APIs): piperacillin and tazobactam. Securing reliable bulk API sources is crucial for manufacturers, healthcare providers, and pharmaceutical distributors to meet global demand, ensure product uniformity, and maintain regulatory compliance.

Understanding ZOSYN’s API Composition

ZOSYN’s formulation comprises two APIs:

• Piperacillin: A broad-spectrum, extended-duration penicillin derivative.
• Tazobactam: A β-lactamase inhibitor that extends piperacillin’s spectrum by inhibiting bacterial enzymes that degrade antibiotics.

Both APIs must meet stringent quality standards, including purity (>99%), potency, and compliance with pharmacopeial specifications such as USP, EP, or JP.
