Iodopol

Sodium Iodide, the active ingredient in Iodopol, is a radioactive iodine presented as a radiopharmaceutical for oral use. It is employed in diagnostic imaging and therapeutic procedures that target thyroid tissue in patients with thyroid disorders. The I‑131 isotope emits beta particles for tissue ablation and gamma radiation for imaging, enabling both treatment and functional assessment of the thyroid gland.

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

Iodopol is used in the management of thyroid conditions where radioactive iodine uptake is required.

- Thyroid cancer: ablation of residual thyroid tissue after thyroidectomy. - Hyperthyroidism (Graves disease, toxic nodular goitre): reduction of excess thyroid hormone production. - Diagnostic thyroid scan: imaging of thyroid function and iodine uptake for assessment.

Iodopol may cause a range of adverse reactions.

Common Side Effects: - Nausea or vomiting. - Dry mouth or altered taste sensation. - Mild neck discomfort or thyroid tenderness. - Transient hypothyroidism.

Serious or Rare Side Effects: - Radiation thyroiditis. - Severe or permanent hypothyroidism requiring hormone replacement. - Bone marrow suppression leading to cytopenias. - Allergic reactions such as rash or anaphylaxis. - Development of secondary malignancies due to radiation exposure.

Use of Iodopol requires careful consideration of several safety aspects. - Pregnancy: avoid unless clearly indicated, as fetal radiation exposure can be harmful. - Breastfeeding: discontinue treatment; iodine-131 can be secreted in breast milk. - Thyroid function monitoring: assess hormone levels before and after therapy. - Radiation safety: implement protective measures for patients, caregivers, and healthcare staff. - Contraindications: known iodine allergy or severe uncontrolled thyroid disease. - Store at ambient temperature below 25°C: keep in the original container, protect from moisture and light.

Iodopol can interact with other medications that affect iodine metabolism or radiation response.

Major Interactions (Avoid): - Lithium: increases iodine uptake and may exacerbate toxicity. - Antithyroid drugs (propylthiouracil, methimazole): reduce the efficacy of radioactive iodine. - Amiodarone: high iodine load interferes with treatment outcomes. - Other iodine‑131 radiopharmaceuticals: cumulative radiation dose may become excessive.

Moderate Interactions (Monitor Closely): - ACE inhibitors: potential impact on renal clearance of iodine. - Diuretics: may alter iodine excretion rates. - Chemotherapy agents: combined bone marrow suppression risk requires monitoring.
