CONRAY 325 vs VASCORAY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated contrast agent that attenuates X-rays by blocking photons, allowing visualization of blood vessels and tissues.
VASCORAY is a fixed combination of iodixanol and calcium sodium edetate. Iodixanol is a nonionic, dimeric, isotonic iodinated contrast medium that increases radiographic contrast by attenuating X-rays. Calcium sodium edetate chelates calcium, potentially reducing contrast-induced nephropathy risk.
Intravenous: 1.0-2.0 mL/kg (325 mg I/mL) for contrast imaging; maximum total dose 250 mL.
0.5-1.0 mL/kg intravenously as a single dose, not to exceed 5 mL/kg total.

Terminal elimination half-life is approximately 1-2 hours in patients with normal renal function. May be prolonged in renal impairment.
Terminal elimination half-life of 8-12 hours in patients with normal renal function; prolonged in renal impairment.
Primarily renal (glomerular filtration); >95% excreted unchanged in urine within 24 hours. Biliary/fecal excretion is negligible (<5%).
Primarily renal (90% unchanged), with 10% biliary/fecal.
