Niopam (Iopamidol)

Iopamidol, the active ingredient in Niopam, is a iodinated non‑ionic contrast media presented as a solution for injection for intra‑arterial, intra‑articular and intracisternal use. It enhances radiographic visualization of vascular and tissue structures during imaging procedures.

GNH USA supplies Niopam as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide.

Iopamidol is used as a radiographic contrast agent to improve visualization of vascular and tissue structures in several imaging procedures.

- Angiography: provides enhanced vessel delineation for diagnostic and interventional procedures. - Arthrography: improves joint space definition to aid musculoskeletal assessment. - Cisternography: highlights cerebrospinal fluid pathways for neuro‑imaging. - CT imaging with contrast: increases tissue contrast to detect lesions and vascular abnormalities.

Adverse reactions may occur after administration of iopamidol. Most are mild and transient, but serious events are possible.

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

Serious or Rare Side Effects: - Anaphylactic or severe allergic reaction. - Acute renal failure or contrast‑induced nephropathy. - Seizures. - Cardiopulmonary arrest. - Severe skin reactions such as Stevens‑Johnson syndrome. - Persistent hypertension or arrhythmias.

Proper assessment and monitoring reduce the risk of complications when using iopamidol.

- Renal function assessment: evaluate serum creatinine and eGFR before administration. - Allergy history: screen for prior iodine or contrast media reactions. - Thyroid status: avoid in patients with uncontrolled hyperthyroidism. - Dose optimization: use the lowest volume necessary for diagnostic quality. - Vital sign monitoring: observe blood pressure and heart rate during and after injection. - Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

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

Major Interactions (Avoid): - Metformin: risk of lactic acidosis in renal impairment; consider temporary discontinuation. - Aminoglycoside antibiotics: additive nephrotoxicity. - Iodine‑containing medications (e.g., thyroid hormone): may exacerbate iodine load.

Moderate Interactions (Monitor Closely): - Diuretics: may affect renal clearance of contrast. - ACE inhibitors or ARBs: monitor renal function and blood pressure. - NSAIDs: increase risk of renal adverse effects; assess renal status before use.
