Niopam (Iopamidol)

Iopamidol, the active ingredient in Niopam, is an iodinated contrast media presented as a sterile solution for intraarterial, intraarticular and intravenous use. It enhances X‑ray attenuation, allowing clearer visualization of vascular and tissue structures during diagnostic imaging procedures in patients undergoing radiographic examinations.

GNH USA supplies Niopam as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Niopam is an iodinated contrast agent used in imaging procedures that require enhanced X‑ray visibility of vascular and tissue structures. - Angiography: improves visualization of blood vessels during diagnostic and interventional procedures. - Arthrography: delineates joint spaces and soft‑tissue structures for orthopedic assessment. - Computed tomography (CT) imaging: provides high‑contrast images of organs and vessels for accurate diagnosis. - Myelography: enhances the spinal canal and nerve root imaging for neurological evaluation.

Adverse reactions to Niopam may vary in frequency and severity.

Common Side Effects: - Warmth or flushing sensation at the injection site. - Metallic taste in the mouth. - Nausea or mild vomiting. - Headache. - Itching or mild skin rash. - Transient hypotension.

Serious or Rare Side Effects: - Severe allergic reaction or anaphylaxis. - Acute renal impairment, especially in patients with pre‑existing kidney disease. - Seizures or neurological disturbances. - Cardiac arrhythmias. - Pulmonary edema. - Persistent hypotension requiring medical intervention.

Prior to administering Niopam, clinicians should assess patient risk factors and follow safety guidelines. - Renal function assessment: evaluate kidney function and consider hydration status. - Allergy history: screen for iodine or contrast media hypersensitivity. - Thyroid disease: be aware of potential iodine load effects. - Concomitant nephrotoxic drugs: monitor for additive renal risk. - Pregnancy and lactation: use only when clearly necessary. - Store at ambient temperature: keep in the original container, protect from light and moisture.

Iopamidol may interact with other medications, requiring careful management.

Major Interactions (Avoid): - Metformin: increased risk of lactic acidosis; discontinue before contrast administration. - ACE inhibitors: may exacerbate renal dysfunction when combined with iodinated contrast. - Nephrotoxic antibiotics (e.g., aminoglycosides): heightened potential for kidney injury.

Moderate Interactions (Monitor Closely): - NSAIDs: may increase risk of contrast‑induced nephropathy; monitor renal function. - Beta‑blockers: can affect hemodynamic response during contrast injection.
