Executive Summary
Fosfomycin disodium, a broad-spectrum antibiotic primarily used against multidrug-resistant bacterial infections, is experiencing renewed clinical interest amid rising antimicrobial resistance (AMR). Its unique mechanism—irreversible inhibition of MurA enzyme involved in bacterial cell wall synthesis—positions it as a vital asset in combating multidrug-resistant urinary tract infections (UTIs) and systemic infections. This report offers a comprehensive market analysis, updates on ongoing clinical trials, and projections for the drug’s commercial trajectory through 2030. With increasing regulatory support and unmet clinical needs, fosfomycin disodium is poised for substantial growth, underscored by expanding indications, favorable regulatory developments, and evolving antimicrobial resistance patterns.
1. Introduction
Fosfomycin disodium (also known as fosfomycin sodium disurbate) is an oral and injectable antibiotic, initially discovered in the 1960s. Recognized for its efficacy against Gram-positive and Gram-negative bacteria, especially problematic multidrug-resistant strains such as ESBL-producing E. coli, carbapenem-resistant Klebsiella pneumoniae, and Pseudomonas aeruginosa, fosfomycin is gaining renewed attention globally. Despite decades of clinical use—mainly in Europe and Asia—it remains underutilized in some markets due to regulatory ambiguities and lack of comprehensive clinical data.
The current global antimicrobial resistance crisis underscores the importance of fosfomycin, especially as newer antibiotics face resistance challenges. This report updates stakeholders regarding ongoing clinical trials, evaluates market dynamics, and forecasts growth trajectories based on emerging data, policy developments, and unmet medical needs.
