Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Pantopaque is an iodinated oil-based contrast agent that attenuates X-rays, allowing visualization of the subarachnoid space during myelography. It acts as a positive contrast medium by increasing the absorption of X-rays in the cerebrospinal fluid.
Radiopaque contrast agent that contains iodine, attenuates X-rays, enhancing vascular and tissue visualization during imaging.
Adults: 5-15 mL (6-18 g iophendylate) intrathecally for myelography via lumbar puncture. No repeated dosing.
The typical adult dose of SCANLUX-370 is 0.1 mg/kg administered intravenously as a single dose, up to a maximum of 7 mg.

Terminal elimination half-life is approximately 6 hours in patients with normal renal function. In renal impairment, half-life is significantly prolonged (up to 24–48 hours in severe impairment), requiring dose adjustment or avoidance.
The terminal elimination half-life of SCANLUX-370 is approximately 1.5-2 hours in patients with normal renal function. This short half-life allows for rapid clearance and minimal accumulation with repeated dosing.
Primarily renal (glomerular filtration) with approximately 60-70% of the dose excreted unchanged in urine within 24 hours. Biliary/fecal excretion accounts for less than 5% of the administered dose; minor metabolism occurs, but the majority is eliminated unchanged via kidneys.
SCANLUX-370 is primarily eliminated via renal excretion, with approximately 85-90% of the dose recovered unchanged in urine within 24 hours. The remaining 10-15% is excreted unchanged in feces via biliary elimination.
