Iopamiro (Iopamidol)

Iopamiro, an iodinated non‑ionic contrast agent, is used to improve visualization of vascular and tissue structures in diagnostic imaging.

• Angiography: provides high‑contrast images of blood vessels for accurate assessment of vascular anatomy and pathology.
• Arthrography: enhances joint space visualization to aid in the diagnosis of ligament, cartilage and intra‑articular lesions.
• Myelography: delineates the spinal canal and nerve roots, facilitating detection of compressive lesions.
• Computed tomography (CT) imaging: improves organ and lesion contrast, supporting precise anatomical evaluation.

• Iopamidol is a water‑soluble, non‑ionic iodine‑containing molecule that absorbs X‑ray photons. After intra‑vascular or intra‑cavitary administration, the iodine atoms increase X‑ray attenuation, creating a temporary radiodense contrast between blood, tissues, and surrounding structures. This enhanced attenuation allows radiologists to differentiate anatomical details during angiography, arthrography, myelography, and CT scans.

Iopamiro may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Warm sensation or flushing at the injection site.
• Mild nausea or vomiting.
• Headache.
• Metallic taste in the mouth.
• Transient urticaria or itching.
• Temporary mild hypotension.

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis) with respiratory distress.
• Acute renal impairment, especially in patients with pre‑existing kidney disease.
• Seizures or convulsions.
• Cardiac arrhythmias or cardiac arrest.
• Pulmonary edema.
• Persistent severe hypotension requiring intervention.

Before administering Iopamiro, clinicians should consider several safety measures.

• Assess renal function: evaluate serum creatinine and eGFR to identify patients at risk of contrast‑induced nephropathy.
• Review allergy history: confirm no prior severe reactions to iodine‑based contrast agents.
• Ensure adequate hydration: encourage fluid intake before and after the procedure to support renal clearance.
• Use the lowest effective dose: tailor volume to the specific imaging requirement.
• Monitor vital signs: observe blood pressure, heart rate and oxygen saturation during and after injection.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.
