Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated radiocontrast agent that attenuates X-rays by increasing radiopacity of blood vessels and tissues, allowing visualization during imaging procedures.
Iopamidol is a nonionic, water-soluble iodinated contrast agent that attenuates X-rays, thereby enhancing radiographic visualization of vascular structures and organs. It does not bind to receptors and has no significant pharmacological activity.
Intravenous: 0.5-2 mL/kg of iomeprol 300-400 mg I/mL for imaging, not exceeding 200 mL total dose; arterial: up to 250 mL per procedure.
Intravenous or intra-arterial administration; dose varies by procedure (e.g., 1-2 mL/kg for CT, up to 50-100 mL for angiography) up to a maximum of 200 mL per procedure.

Terminal elimination half-life is approximately 1.5-2 hours in patients with normal renal function. In renal impairment, half-life is prolonged (up to 10-30 hours in severe impairment), necessitating dose adjustment and monitoring. The half-life is not significantly affected by hepatic impairment.
Terminal elimination half-life is approximately 2 hours in patients with normal renal function (creatinine clearance >90 mL/min). In moderate renal impairment it extends to 3-5 hours; in severe renal impairment (CrCl <30 mL/min) it can exceed 30 hours, prolonging diagnostic window.
Iomeprol is almost exclusively eliminated via renal glomerular filtration, with 92-98% of the administered dose recovered unchanged in urine within 24 hours. Less than 2% is excreted in feces via biliary elimination. In patients with normal renal function, renal clearance approximates glomerular filtration rate.
Primarily renal excretion of intact drug via glomerular filtration; >90% excreted unchanged in urine within 24 hours. Less than 1% fecal or biliary elimination.
