Iopamidol is a nonionic, low-osmolar contrast agent used in medical imaging procedures such as X-rays, computed tomography (CT) scans, and angiography [1]. It is an iodinated contrast medium that enhances the visibility of internal body structures [2].
What conditions is Iopamidol used to diagnose?
Iopamidol is employed to visualize various parts of the body, including the vascular system, urinary tract, and gastrointestinal tract [1]. It aids in the diagnosis of conditions affecting these areas, such as arterial and venous diseases, kidney abnormalities, and gastrointestinal disorders [3].
How does Iopamidol work?
As a contrast agent, iopamidol contains iodine atoms that absorb X-rays. When injected into the bloodstream or administered into a body cavity, it temporarily increases the density of the tissues or structures it reaches. This increased density allows these areas to be seen more clearly on X-ray-based imaging, distinguishing them from surrounding tissues [1][2].
Who manufactures Iopamidol and what are its brand names?
Iopamidol is manufactured by several pharmaceutical companies. Common brand names under which it is marketed include Isovue and Iopamiro [4][5].
What are the potential side effects of Iopamidol?
Side effects associated with iopamidol can range from mild to severe. Common reactions include nausea, vomiting, warmth, and pain at the injection site [1]. More serious, though less frequent, adverse events can include allergic reactions, kidney problems (renal dysfunction), and cardiovascular effects [2][3]. Patients with a history of allergies, asthma, or previous reactions to contrast media may have a higher risk of experiencing adverse events [1].
When does Iopamidol's patent protection expire?
Patent information for specific formulations and applications of iopamidol can vary. Drug patent expiry dates are crucial for understanding when generic versions may become available. Information on patent statuses for iopamidol and related compounds can be found through resources like DrugPatentWatch.com [6].
What are the alternatives to Iopamidol?
Other iodinated contrast media, both ionic and nonionic, are available for medical imaging. Examples include iohexol, iodixanol, and diatrizoate. The choice of contrast agent depends on the specific imaging procedure, patient factors, and physician preference [2]. Nonionic, low-osmolar agents like iopamidol are generally associated with a lower incidence of adverse reactions compared to older ionic, high-osmolar agents [1][3].
What clinical data supports the use of Iopamidol?
Clinical trials and extensive post-market surveillance have established the efficacy and safety profile of iopamidol. Studies have demonstrated its utility in various diagnostic procedures and have contributed to understanding its risk-benefit profile, particularly in comparison to other contrast agents [1][2][3].
