It has been suggested that the potential for thrombo-embolic complications is greater with the use of non-ionic contrast agents than with ionic contrast agents. The increasing use of interventional therapy in patients with acute coronary disease makes the discussion of a possible relationship between thrombo-embolic complications and use of non-ionic contrast media pertinent. It has been shown that ionic contrast media have a marked effect on the coagulation system and platelet function. The non-ionic contrast media have a less pronounced effect on the coagulation system and platelet function

Angiographic contrast media (CM) may cause both vasodilatation and vasoconstriction, effects that can only be partly be explained by the media's hyperosmolality. The present study describes a CM-induced vasoconstriction of isolated rabbit coronary arteries that depends on chemotoxicity and ion content of the CM. Rings of arteries were mounted in tissue baths and the constrictions induced by different CM were measured. Iotrolan and iodixanol (nonionic dimers) caused the most powerful constrictions followed by iohexol (non-ionic monomer) and mannitol. Ioxaglate (ionic dimer) and diatrizoate (ion

Iodinated contrast media (CM) are administered to millions of patients every year, yet controversy continues to exist regarding the safety of the various agents. Iodinated CM are either ionic or non-ionic, and vary in their osmolality relative to plasma. It is generally accepted that first-generation ionic, high-osmolality CM (HOCM) are less well tolerated than non-ionic, low-osmolar CM (LOCM). However, whether there are differences in safety among the remaining classes or individual CM, particularly with regard to nephrotoxicity and ischaemic complications, remains controversial.

The cells were grown to confluency in monolayer cultures in a chemically-defined serum-free medium before the contrast media were added, to give final concentrations corresponding to 0–100mg iodine/ml.

Background: Nonionic, low osmolar agents are now used nearly universally for intravenous (IV) contrast administration in computed tomography. The osmolarity of a contrast agent is considered to be responsible for adverse effects in patients injected with contrast media. With the increase in its utilization, acute adverse reactions are suspected to rise substantially. Regardless of the usage of low osmolar non-ionic agents to reduce adverse effects, a large number of reactions are still experienced by patients. However, the frequency of immediate adverse contrast reactions to various low osmola

The non-ionic monomeric contrast media iopamidol and iohexol were compared concerning enhancement in the organs of the upper abdomen in CT. The average peak enhancement above the base line for the 2 contrast media in the liver, vena cava, aorta and spleen was calculated. No difference between the contrast media was found with regard to increase in contrast enhancement. No correlation between the peak enhancement and body weight and body surface was found with either of the 2 contrast media.

Purpose The aim of this study was to determine the compatibility of epirubicin-loaded DC bead™ with different non-ionic contrast media over a period of seven days when stored light protected under refrigerated conditions. Methods DC bead™ (2 ml) (Biocompatibles UK Ltd) of the bead size 70–150 µm ( = DC bead M1) or bead size 100–300 µm were loaded with 75 mg epirubicin powder formulation (Farmorubicin® dissolved in 3 ml water for injection to a concentration of 25 mg/ml) or 76 mg epirubicin injection solution (Epimedac® 2 mg/ml) within 2 h or 6 h, respectively. After removal of the excess solut

The synthesis of prostacyclin (PGI2) was studied in isolated perfused rat lungs during the infusion of radiographic contrast media into the pulmonary circulation. At the same molar concentration, diatrizoate, iopamidol, and NaCl fairly equally stimulated the generation of PGI2. A bolus injection of histamine also enhanced the formation of PGI2. A high dose of ionic diatrizoate and hypertonic saline (0.4 mol/l) caused considerable pulmonary edema, which was less marked with non-ionic iopamidol. Experiments with 125I-labeled contrast media indicated rapid efflux of contrast media from the lungs.
