Description

Mezlocillin Sodium is a broad-spectrum, semisynthetic acylureidopenicillin antibiotic. It is valued for its enhanced activity against Gram-negative bacteria, including Pseudomonas aeruginosa, compared to earlier penicillins. This product is essential for pharmaceutical manufacturers and research institutions developing injectable antibiotic formulations and conducting microbiological studies.

Application

• Active Pharmaceutical Ingredient (API) for the manufacture of injectable antibiotic drugs.
• Research and Development of new antibacterial therapies and combination treatments.
• Microbiological Studies as a reference standard for susceptibility testing and mechanism of action research.
• Veterinary Pharmaceutical Production for treating bacterial infections in animals.
• Hospital Compounding (where regulated and approved) for specific patient needs.
