Executive Summary
Polymyxin B sulfate, a potent antibiotic classified within the polymyxin class, is widely utilized as a pharmaceutical excipient and active pharmaceutical ingredient (API) in combating multi-drug resistant (MDR) gram-negative bacterial infections. Its rising prominence is driven by escalating antimicrobial resistance (AMR), regulatory approvals, and increasing demand in both hospital and outpatient settings. This report analyzes current market dynamics, technological advancements, and forecasted financial trends, aiming to inform stakeholders, investors, and industry players about the opportunities and risks associated with Polymyxin B sulfate.
Introduction
Polymyxin B sulfate is an antimicrobial agent primarily used for systemic infections caused by MDR gram-negative bacteria such as Pseudomonas aeruginosa, Klebsiella pneumoniae, and carbapenem-resistant strains. Originating from the fermentation of Bacillus polymyxa, the compound was introduced into clinical practice in the 1950s but faced restriction due to toxicity concerns—nephrotoxicity and neurotoxicity. Recent resurgence stems from the antimicrobial resistance crisis, positioning Polymyxin B sulfate as a critical last-line therapy.
