Diatrizoate Sodium is an iodinated radiopaque X-ray contrast medium. Diatrizoate sodium blocks X-rays, thereby allowing body structures containing iodine to be delineated in contrast to those structures that do not contain iodine and allowing visualization of these areas. This contrast agent is used as a diagnostic aid in angiography, urography and radiography. (NCI05)

5 Pharmacology and Biochemistry
5.1 Absorption, Distribution and Excretion

Radioiodine is excreted in human milk during lactation. It is not known whether GLOFIL-125 is excreted in human milk.

US Natl Inst Health; DailyMed. Current Medication Information for Glofil-125 (iothalamate sodium, I-125) Injection (June 2007). Available from, as of July 23, 2012: https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=2c07ce91-cc83-45e3-bd2b-f923a9c8286c


The renal clearance of sodium iothalamate in man closely approximates that of inulin. The compound is cleared by glomerular filtration without tubular secretion or reabsorption.
