Iobitridol 250 vs iohexol 240 in phlebography of th lower limbs. A double-blind clinical trial.

Abstract

Iobitridol 250 (Xenetix 250) was compared with iohexol 240 (Omnipaque 240) in phlebography of the lower limbs by means of a multicenter, randomized double-blind trial in 70 patients. No significant difference was demonstrated between the 2 groups in terms of diagnostic efficacy, image quality or clinical safety. Only minor reactions were recorded in the 2 groups, essentially consisting of mild or moderate heat sensations. The only insufficiently informative examinations were not due to the contrast agent. Iobitridol 250 therefore appears to be a well-tolerated contrast medium, suitable for use in phlebography of the lower limbs.
