OPTIRAY 300 vs OPTIRAY 350
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Optiray 300 (ioversol) is a nonionic iodinated contrast medium that attenuates X-rays, enhancing vascular and tissue contrast during imaging. It acts by increasing the density of blood vessels and tissues to X-rays, thereby improving visualization of anatomical structures.
Iodinated radiocontrast agent that attenuates X-rays and enhances visualization of vascular structures and organs during imaging procedures.
Intravenous administration: 50-150 mL per injection (up to 250 mL for CT imaging). Typical adult dose: 1-2 mL/kg body weight (up to 150 mL) given as a bolus or rapid infusion. Intrathecal administration: 8-12 mL for myelography.
Intravenous administration: 50-150 mL of 350 mgI/mL solution for contrast-enhanced CT; dose determined by procedure, body weight, and clinical indication. Intra-arterial: Varies per procedure, typically 30-60 mL total. Maximum single dose not established; avoid exceeding 5 mL/kg body weight.

Terminal elimination half-life is approximately 1.5-2 hours in patients with normal renal function. In patients with impaired renal function, half-life may be prolonged significantly (up to 30 hours or more), necessitating dose adjustment or avoidance.
2.0 ± 0.4 hours in patients with normal renal function (creatinine clearance >90 mL/min); prolonged to 10-40 hours in severe renal impairment (CrCl <30 mL/min)
Primarily renal elimination via glomerular filtration; approximately 95-100% of the administered dose is excreted unchanged in urine within 24 hours. A negligible amount is eliminated via biliary/fecal routes (<1%).
Renal: 90-95% as unchanged drug via glomerular filtration within 24 hours; biliary/fecal: <5%
