Iodohippurate

An iodinated analogue of p-aminohippuric acid that the kidneys remove mainly by tubular secretion: labelled with iodine-131 since 1960, and later with iodine-123, it is used in renography to assess renal plasma flow. This family brings together other impurities.

Did you know?For many years the iodine-131 version was the only radiopharmaceutical for renography: in healthy kidneys about 85% of the dose is already found in the urine 30 minutes after injection.
