Urinary excretion of Iopamidol following intrathecal administration.

No iodinated compound other than Iopamidol was found in the urine of subjects who received intrathecal injection of 10 ml of Iopamiro "300". The compound was neither metabolized nor altered in its optical configuration and urinary iodide content was always in the normal range. Between 72 and 85% of injected Iopamidol was excreted within 72 h of injection.
