Niopam (Iopamidol)

Iopamidol, the active ingredient in Niopam, is an iodinated contrast agent (non‑ionic, low‑osmolality) presented as a solution for injection for intra‑arterial and intravenous use. It provides enhanced X‑ray attenuation to improve visualization of vascular and tissue structures during imaging procedures such as CT, angiography, urography and myelography in patients requiring diagnostic radiology.

GNH USA supplies Niopam as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with a focus on quality assurance and regulatory compliance, and reliable delivery.

Niopam (iopamidol) is employed as a radiographic contrast medium to enhance visualization of vascular and tissue structures during imaging procedures.

- X‑ray/CT imaging: Improves delineation of anatomical structures and lesions, aiding diagnostic accuracy. - Angiography: Highlights blood vessels to facilitate assessment of vascular patency and pathology. - Urography: Enhances visualization of the urinary tract for detection of obstruction or disease. - Myelography: Provides contrast within the spinal canal to assist evaluation of the spinal cord and nerve roots.

Adverse reactions to iodinated contrast agents may vary in frequency and severity.

Common Side Effects: - Warm sensation or flushing at injection site. - Metallic taste or mild nausea. - Headache or transient dizziness. - Mild urticaria or itching.

Serious or Rare Side Effects: - Severe allergic reaction or anaphylaxis. - Acute kidney injury or contrast‑induced nephropathy. - Hypotension or cardiovascular collapse. - Pulmonary edema or respiratory distress.

Prior to administration, specific safety measures should be observed to minimize risk.

- Assess renal function: evaluate serum creatinine and eGFR before use. - Review allergy history: identify prior reactions to iodinated contrast or related agents. - 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 hypersensitivity to iodinated contrast agents. - Store at ambient temperature: keep in original container, protect from moisture and light.

Iopamidol may interact with other medicines, influencing safety or efficacy.

Major Interactions (Avoid): - Concurrent administration of other iodinated contrast agents: cumulative iodine load may increase toxicity. - Nephrotoxic drugs (e.g., aminoglycosides, high‑dose NSAIDs): heightened risk of renal impairment. - Metformin in patients with reduced renal function: risk of lactic acidosis.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may mask tachycardia that signals an adverse reaction. - Diuretics: can affect fluid balance and renal clearance of contrast. - Thyroid hormone therapy: excess iodine may alter thyroid function tests. - ACE inhibitors or ARBs: may increase susceptibility to contrast‑induced nephropathy.
