ANGIOVIST 292 vs MAGNEVIST
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Angiovist 292 (diatrizoate meglumine and diatrizoate sodium) is an ionic, high-osmolar iodinated contrast agent. It functions by absorbing x-rays due to the high atomic number of iodine, thereby enhancing the radiopacity of vascular structures and organs during diagnostic imaging. It also increases the osmolarity of the intravascular compartment, which can lead to hemodynamic effects.
Gadopentetate dimeglumine is a paramagnetic contrast agent that shortens T1 and T2 relaxation times in tissues where it accumulates, enhancing signal intensity on T1-weighted magnetic resonance imaging (MRI). It distributes extracellularly and does not cross the intact blood-brain barrier, but accumulates in areas of disrupted barrier or abnormal vascularity.
Intravenous administration: 50-150 mL of a 292 mg iodine/mL solution for adults, depending on the imaging procedure, with a maximum total dose of 300 mL per procedure.
0.2 mL/kg (0.1 mmol/kg) intravenously, up to 0.6 mL/kg (0.3 mmol/kg) for certain indications, with a maximum of 20 mL per dose.

Terminal elimination half-life is approximately 2 hours in patients with normal renal function; prolonged to >30 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life in patients with normal renal function is approximately 1.6 hours. In patients with impaired renal function, half-life is prolonged (up to 30 hours with GFR <30 mL/min).
Primarily renal; >90% of dose excreted unchanged in urine within 24 hours. Fecal excretion is negligible (<1%).
Renal excretion of unchanged gadopentetate dimeglumine accounts for approximately 99% of the administered dose within 72 hours. Biliary/fecal excretion is negligible (<0.5%).
