The first time i saw an INTRAVENOUS PYELOGRAM being done, i observed that the list of drugs included the OMNIPAQUE. So i began to wonder what omnipaque was? It was obvious that the word was a trade name of a drug. This is what i learnt later... Read below ...
Iohexol is a contrast agent, sold under the trade name Omnipaque.
It is available in various concentrations, from 140 to 350 milligrams of iodine per milliliter.
Omnipaque 350 is commonly used as a contrast agent during coronary angiography.
The osmolality of iohexol ranges from 322 mOsm/kg—approximately 1.1 times that of blood plasma—to 844 mOsm/kg, almost three times that of blood.
Despite this difference, iohexol is still considered a low-osmolality contrast agent; the osmolality of older agents, such as diatrizoate, may be more than twice as high.
