Iotrolan (trade name Isovist) is an

X-ray techniques.[1]

As of 2021[update], it is unknown whether it is still marketed anywhere in the world.

Medical uses

It is particularly used to image spaces surrounding the

urinary tract) and hysterosalpingography (imaging of uterus and fallopian tubes).[2][3] It can also be used to image joint spaces and in endoscopic retrograde cholangiopancreatography (ERCP).[citation needed
]

Contraindications

Hysterosalpingography is contraindicated during pregnancy and during acute inflammation in the

pelvic region.[2]

Adverse effects

The most common side effects are nausea and vomiting. Redness and a hot feeling of the skin is relatively common when the medication is injected into a vein. When injected into the cerebrospinal fluid, headache is among the most common adverse effects, and sometimes confusion or hallucinations can occur. Allergy-like reactions such as fever, hypotension (low blood pressure) and shock have also been observed.[2]

Interactions

Drug interactions are similar to other iodine-containing contrast agents. Iodine-131, a radioactive isotope used for thyroid imaging (scintigraphy) and therapy of thyroid cancers, can be less effective when used within two to six weeks after application of iotrolan because of residual iodine in the body. Iotrolan can slow down the excretion of the diabetes drug metformin, potentially resulting in lactic acidosis.[2]

Chemistry and mechanism of action

Chemically, the substance is a

non-ionic but water soluble.[2]
