Iohexol Injection

This product is a commonly used contrast agent for X-ray and CT examinations, and can be used in blood vessels, spinal canals, and body cavities. Animal test results show that this product has an enhancement effect on dog liver, abdominal aorta, and CT scan images. Toxicological effects: Proteinuria occurs during dog renal artery angiography.

The main ingredient of this product, iohexol, has the chemical name: N, N'-bis (2,3-dihydroxypropyl) -5- [N- (2,3-dihydroxypropyl) acetamido] -2,4,6-triiodo-1,3-benzenedicarbamide. Molecular formula: C19H26I3N3O9 Molecular weight: 821.14

This product is a colorless to light yellow clear liquid. This product is a non-ionic water-soluble contrast agent containing three iodine atoms, with an iodine content of 46.4%. It is in the form of a sterilized aqueous solution, ready to use, and has different iodine concentrations, including 140, 180, 240, 300 or 350 mg iodine per ml.

1. Intravascular application: This product is used clinically for urography and cardiovascular angiography in adults and children, as well as cerebral angiography, peripheral and various arterial angiography, venography, digital subtraction and CT enhanced scanning in adults. 2. Subarachnoid application: It is suitable for myelography in adults and children, and for CT scanning of the brain pool after subarachnoid injection. 3. Intracavitary application: It is suitable for various body cavity examinations, including oral administration. Such as arthrography; endoscopic retrograde pancreaticobiliary angiography (ERCP); hernia sac angiography; urography; hysterosalpingography; sialography and various gastrointestinal examinations using oral water-soluble contrast agents.

1A small number of patients may experience some mild reactions, such as: short-term warmth, slight pain, flushing, nausea/vomiting, mild chest pain, skin itching and urticaria. 2Headache, nausea and vomiting are the most common adverse reactions in myelography. Severe headache lasting for several days may occur intermittently. Other mild adverse reactions found so far include short-term dizziness, back pain, neck pain or pain in the limbs and various sensory abnormalities. There have also been cases where the EEG recording showed unclear transient changes (slow waves). Aseptic meningitis has been found after myelography with water-soluble contrast agents. Similar situations have been reported for myelography using this product, but they are very mild and short-lived. 3There are also reports of delayed adverse reactions in some patients within hours to days after contrast. 4Serious adverse reactions rarely occur, but shock, convulsions, coma, severe laryngeal edema or bronchospasm, renal failure, death, etc. have also been reported. According to statistics of 300,000 cases collected by Professor Katayama and others in Japan, the incidence of mild adverse reactions to non-ionic contrast agents (including iohexol) is about 3.08%, the incidence of moderate adverse reactions is about 0.04%, and the incidence of severe adverse reactions is about 0.004%.

1. Patients with obvious thyroid disease. 2. Patients with a history of severe reaction to iohexol injection. 3. Patients with a history of epilepsy should not use iohexol in the subarachnoid space. 4. Lumbar puncture is contraindicated for patients with severe local infection or systemic infection who may develop bacteremia. 5. Since radiation exposure should be avoided as much as possible during pregnancy, the pros and cons of X-ray examinations need to be weighed. Unless the doctor deems it necessary, pregnant women should not use it. 6. Due to dose limitations, it is not advisable to repeat angiography immediately for those who fail to perform angiography.

Precautions for children: Precautions for pregnancy and lactation: Please refer to contraindications and precautions. Precautions for the elderly:

1. The use of contrast media may cause transient renal insufficiency, which may cause lactic acidosis in diabetic patients taking hypoglycemic drugs (metformin). As a precaution, biguanide hypoglycemic drugs should be discontinued 48 hours before the use of contrast media, and the medication should be resumed only after renal function has stabilized. 2. Patients treated with interleukin-2 within two weeks are at increased risk of delayed reactions (cold-like symptoms and skin reactions). 3. All iodine-containing contrast media may interfere with thyroid function tests. The iodine binding capacity of thyroid tissue may be reduced by contrast media and may take several days or even two weeks to fully recover. 4. High concentrations of contrast media in serum and urine may affect laboratory measurements of bilirubin, protein, or inorganic substances (such as iron, copper, calcium, and phosphorus). These tests should not be performed on the day of contrast media use.

Keep away from light and store in a sealed container.
