Niopam (Iopamidol)

Iopamidol, the active ingredient in Niopam, is an iodinated contrast agent presented as a solution for injection for intra‑arterial and intravenous use. It provides radiopaque contrast to enhance visualization of vascular structures and organs during imaging procedures such as angiography, CT scans, and urography, and is approved for use throughout the European Union.

GNH USA supplies Niopam as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, diagnostic imaging centres and clinics worldwide, ensuring consistent quality and regulatory compliance across markets.

Niopam, an iodinated contrast agent, is employed in radiographic procedures that require enhanced visualization of vascular and organ structures. - Angiography: improves delineation of blood vessels during catheter‑based imaging. - Computed tomography (CT) imaging: increases tissue contrast to aid diagnosis of lesions and vascular anatomy. - Intravenous urography: highlights urinary tract structures for functional assessment. - Myelography: provides clear contrast of the spinal canal and nerve roots. - Contrast‑enhanced radiographic examinations: facilitates detailed imaging of organs such as liver, heart and lungs.

Adverse reactions to Niopam may vary in frequency and severity.

Common Side Effects: - Warmth or flushing sensation at injection site - Nausea or vomiting - Mild headache - Transient hypotension

Serious or Rare Side Effects: - Severe allergic reaction or anaphylaxis - Acute renal impairment or contrast‑induced nephropathy - Pulmonary edema or respiratory distress - Cardiac arrhythmias

When using Niopam, several precautions should be observed to minimize risk. - Assess renal function: evaluate serum creatinine and eGFR before administration. - Review allergy history: identify prior reactions to iodinated contrast or iodine‑containing substances. - Use lowest effective dose: tailor volume to imaging requirement and patient size. - Monitor vital signs: observe blood pressure and heart rate during and after injection. - Avoid in patients with known iodine hypersensitivity: consider alternative imaging methods. - Store at ambient temperature: keep in original container, protect from moisture and light.

Niopam may interact with certain medicines, requiring attention to avoid clinically significant effects.

Major Interactions (Avoid): - Metformin in patients with impaired renal function: risk of lactic acidosis; discontinue metformin before and after contrast exposure. - Concurrent use of other iodinated contrast agents within 24 hours: cumulative iodine load may increase toxicity.

Moderate Interactions (Monitor Closely): - Thyroid hormone therapy: excess iodine can alter thyroid function; monitor thyroid tests. - Diuretics: may affect renal clearance of contrast; observe renal parameters. - NSAIDs: can compound renal stress; assess kidney function during use.
