Introduction
Iohexol, a nonionic contrast agent primarily used in radiographic imaging procedures, has become integral to diagnostic medicine. Its primary function is to enhance imaging clarity in procedures such as computed tomography (CT) scans and angiography, facilitating accurate diagnosis. Due to its widespread application, a robust supply chain of pharmaceutical-grade iohexol is critical for hospitals, imaging centers, and medical facilities globally. This article provides an in-depth analysis of the key suppliers of iohexol, their manufacturing capabilities, regional presence, regulatory standing, and market dynamics shaping supply.
Overview of Iohexol Supply Chain
The supply of iohexol involves pharmaceutical manufacturing companies that produce high-purity contrast agents compliant with global regulatory standards. The supply chain encompasses research and development, manufacturing, quality assurance, distribution, and logistics. Given its medical application, suppliers must adhere to stringent Good Manufacturing Practices (GMP) and secure approvals from agencies such as the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA), and other national regulators.
