Excretion of metrizamide (Amipaque) in humans following lumbar subarachnoid injection.
The excretion of metrizamide through the kidneys and intestinal tract was determined in 10 patients submitted to myelography because of sciatica, for a period of 7 days following the examination. In the faeces, less than 5 per cent of the injected contrast medium was recovered during this period. Total recovery in the urine varied considerably from patient to patient, but most of the contrast medium was excreted during the first 48 hours. From the fourth day on, only small amounts were excreted, but even on the 7th day 3 to 11 mg iodine remained, which corresponds to 6 to 22 mg of metrizamide.
