Description

Fosfomycin Sodium is the sodium salt form of the broad-spectrum bactericidal antibiotic, fosfomycin. This compound is valued for its unique mechanism of action, inhibiting bacterial cell wall synthesis at an early stage, which makes it effective against a range of Gram-positive and Gram-negative bacteria, including some resistant strains. It is a critical active pharmaceutical ingredient (API) primarily demanded by the pharmaceutical industry for the formulation of injectable antibiotics.

Application

• Pharmaceutical API: Primary use as the active ingredient in sterile injectable formulations for systemic antibiotic therapy.
• Treatment of Severe Infections: Used in hospitals for treating complicated urinary tract infections (UTIs), respiratory tract infections, and septicemia.
• Combination Therapy: Employed in combination with other antibiotics to enhance efficacy and combat multi-drug resistant bacterial infections.
• Veterinary Medicine: Formulated for use in veterinary injectables to treat bacterial infections in livestock and companion animals.
• Research & Development: Serves as a reference standard and key intermediate in antimicrobial research and new drug development.
