Introduction
The combination of Cilastatin Sodium and Imipenem represents a critical therapeutic duo within the broad spectrum of antibiotics used for severe bacterial infections. Imipenem, a carbapenem antibiotic, exerts potent bactericidal activity against a wide array of Gram-positive and Gram-negative bacteria. Cilastatin Sodium functions as a renal dehydropeptidase inhibitor, preventing the rapid degradation of imipenem in the kidney, thereby enhancing its efficacy and allowing for higher therapeutic concentrations. As the demand for broad-spectrum antibiotics surges amid rising antimicrobial resistance, ensuring a reliable supply chain for Cilastatin Sodium and Imipenem is imperative for healthcare providers and pharmaceutical manufacturers.
Market Overview
The global market for imipenem-cilastatin is driven by increasing prevalence of multi-drug resistant infections, hospital-acquired infections, and the expanding use of carbapenem antibiotics in critical care settings. The manufacturing landscape is concentrated among key pharmaceutical companies specializing in generics and active pharmaceutical ingredients (APIs). The dominance of certain suppliers influences global availability, pricing, and regulatory adherence.
