Contrast media pharmacovigilance in diagnostic imaging: A tool to enhance

The use of contrast media is necessary to some diagnostic procedures; unfortunately, the administration is associated in some cases with adverse drug reactions (ADRs); some reactions are common and the probability increases expecially in pluripathological patients; in these cases the polypharmacotherapy can increase drug interaction risk. Frequency, severity and other features of adverse drug reactions due to contrast media should be monitored; however contrast media ADR are often underreported for many reasons, such as the habit of the radiologist to report these reaction, the availability of standard forms and the interaction between radiologists and pharma-covigilance referents. It is necessary to promote and implement pharmacovigilance actions for constant moni-toring of patients undergoing media contrast agents to diagnostic procedure sand an electronic consultation system on the incidence of hypersensitivity reactions to contrast media should be introduced.
