IV contrast agents, often containing iodine, are designed to enhance imaging during procedures like CT scans. They are not absorbed by the body because they are large molecules that remain within the vascular system, allowing for clear visualization of blood vessels and organs. Additionally, these agents are typically excreted by the kidneys, minimizing their absorption and potential toxicity. This property ensures that they provide imaging benefits without significantly altering physiological processes.

The simple answer as to why dosages of oral medication differ from intravenous (IV) doses of pharmaceuticals is that to be effective, oral medication must be absorbed in the digestive system.

Yes, your body can process out some of the IV medication, but this is different than your body having to absorb it in the gastrointestinal tract.
