The adverse effects following lumbar myelography and ventriculography with meglumine iothalamate (Conray Meglumin), meglumine iocarmate (Dimer-X, Bis-Conray) and metrizamide (Amipaque), and after thoracic and cervical myelography and cisternography with metrizamide are reviewed. In addition to the published material information given to Nyegaard & Co. from several hospitals participating in clinical trials with metrizamide is also reported. The frequency of minor adverse effects (headache, nausea, vomiting) seems to be about the same with all the three water-soluble contrast media. Convulsions, either localized to the lower part of the body or generalized, may be a problem with meglumine iothalamate and meglumine iocarmate, while the epileptogenic effect is markedly lower with metrizamide. With a technique directed towards preventing contrast medium of high concentration from passing intracranially, the frequency of serious adverse effects may be kept at a very low level. Late adverse effects (adhesive arachnoiditis) occurring after all other water-soluble contrast media are a very minor problem after metrizamide. Serious complications have not been recorded following ventriculography and cisternography with metrizamide. Metrizamide is considered to be the water-soluble contrast medium best suited for use in the subarachnoid space and cerebral ventricles.

Meglumin-Iodrinat has been synthesized as the contrasting part of Myelografin by Schering AG. and tested for lumbar Myelography in animal experiments. The excellent neural and general compatibility justified a first clinical trial. 200 patients were examined, 100 each with following upright or lying down positions. There were no local symptoms, no signs of spinal or cerebral irritation. This is seen to be the main advantage compared with drugs used so far. Intensity of contrast corresponded with that of Conray 60 and Dimer X. The most common complaints like headache and nausea were interpreted as CSF hypotension and can be clearly reduced by lying down. Also the concentration of the contrastmedium diminishes more rapidly with the patient lying down.

Meglumine sodium diatrizoate (Urografin), iopamidol, and iohexol were compared in a double-blind, randomized study of 287 patients undergoing elective cardiac angiography. Ninety-six patients received Urografin, 98 received iopamidol, and 92 received iohexol. The groups were similar in all respects. Variables measured before and after contrast injection were left ventricular end-diastolic pressure (LVEDP), left ventricular systolic pressure (LVSP), systolic arterial pressure (SAP), RR, PR, and QTc intervals, QRS duration, ST segment change greater than 2 mm, arrhythmias, and symptoms. The adequacy of coronary and ventricular opacification was assessed by two experienced observers. Following left ventriculography, small rises in LVEDP occurred with iopamidol and iohexol (mean +/- SD: 18 +/- 7 to 21 +/- 7 mmHg) and a moderate fall in LVSP with Urografin (150 +/- 32 to 133 +/- 32 mmHg). Following coronary angiography there was a progressive fall in SAP (130 +/- 26 to 117 +/- 30 mmHg) and prolongation of RR intervals (900 +/- 138 to 1,266 +/- 692 msec) and QTc (440 +/- 61 to 471 +/- 73 msec) and QRS duration (87 +/- 25 to 100 +/- 27 msec) with Urografin. There was a small fall in SAP with iopamidol (138 +/- 25 to 128 +/- 27 mmHg) and prolongation of QRS duration with iohexol (85 +/- 29 to 90 +/- 24 msec). Other parameters were not significantly affected. Frequent bradyarrhythmias (sinus pause 14.5%, asystole 6%) and ST segment depression occurred following Urografin. Urografin was less well tolerated, with 10% of patients experiencing severe nausea or vomiting and 30% of patients experiencing extreme heat sensation. Differences between iohexol and iopamidol were minor.(ABSTRACT TRUNCATED AT 250 WORDS)

Tolerance of two contrast media was compared by a double blind study. High doses of iodine (45 g) were used for both contrast substances. Sodium Ioglicinate was giving best radiological contrast but produced more side-effects, especially nausea, as compared to Methylglucamine-Ioglicinate. On the contrary Methylglucamine-Ioglicinate did not give best density but did produce less side-effects. Thus the investigator has to consider very carefully, which of the compounds has to be preferred.
