Iohexol

Absorption

Small amounts are absorbed through the bladder via intravesical instillation. Following intrauterine instillation, the majority of the medium within the uterine cavity is discharged into the vagina immediately upon termination of procedure. However, any medium retained in the uterine or peritoneal cavity is absorbed systemically within 60 minutes. May not be absorbed for up to 24 hours if tubes are obstructed and dilated.

Toxicity

Non-ionic radiocontrast agents like iohexol are cytotoxic to renal cells. The toxic effects include apoptosis, cellular energy failure, disruption of calcium homeostasis, and disturbance of tubular cell polarity, and are thought to be linked to oxidative stress.

Imaging agent.

Background

Iohexol is an effective non-ionic, water-soluble contrast agent which is used in myelography, arthrography, nephroangiography, arteriography, and other radiographic procedures. Its low systemic toxicity is the combined result of low chemotoxicity and low osmolality.

Indications

Iohexol ia used in myelography, arthrography, nephroangiography, arteriography, and other radiographic procedures.

What are the applications of Application

Iohexol is a nonionic and water-soluble contrast agent that can induce inhibition of electrical activity.

Definition

ChEBI: A benzenedicarboxamide compound having N-(2,3-dihydroxypropyl)carbamoyl groups at the 1- and 3-positions, iodo substituents at the 2-, 4- and 6-positions and an N-(2,3-dihydroxypropyl)acetamido group at the 5-position.

General Description

Iohexol is a low-osmolar, nonionicmonomer with 46% iodine content. Iohexol is one ofthe few iodinated contrast agents indicated for intrathecaluse (myelography). Only selected concentrations of theproduct have this indication. Besides myelography, iohexolfinds widespread use in excretory urography, angiography,and CT procedures. Specific concentrations may have additionalindications in adults and/or children for arthrography,hysterosalpingography, endoscopic retrograde pancreatography,cholangiopancreatography, herniography, voidingcystourethrography, oral pass-thru examination of the GItract or CT of the abdomen.

Pharmacokinetics

Iohexol is an effective non-ionic, water-soluble contrast agent which is used in myelography, arthrography, nephroangiography, arteriography, and other radiographic procedures. Its low systemic toxicity is the combined result of low chemotoxicity and low osmolality.
