Contrast Agent for CT & Cath Lab

OptiRay® (Ioversol)

Optiray® was first available in 1989 and also became available in the pre-filled syringe form for manual or automatic injection in 1996 (Optiject®) in France, Belgium, Luxembourg, and Switzerland. It is known as Ultraject® in the rest of the world.

Contrast Induced Nephropathy (CIN) is a well-documented concern in CT. Factors leading to CIN are high viscosity, high osmolality, low hydrophilicity. Optiray has low viscosity, low osmolality and high hydrophilicity meaning that it will have greater difficulty crossing the cell membrane to cause neural toxicity. It is a balanced molecule structure1,2.
