Natriumjodid (131i) Curium (Sodium Iodide (131i))

Sodium Iodide I-131, the active ingredient in Natriumjodid (131i) Curium, is a radioactive iodine presented as an oral radiopharmaceutical solution for oral use. It is employed in the treatment of thyroid cancer, management of hyperthyroidism, and in diagnostic imaging of thyroid tissue.

GNH USA supplies Natriumjodid (131i) Curium as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide, adhering to EU regulatory standards.

Natriumjodid (131i) Curium, a radioactive iodine, is used in conditions affecting thyroid function.

- Thyroid cancer ablation: eliminates residual thyroid tissue after surgery to reduce recurrence risk. - Hyperthyroidism (e.g., Graves disease): reduces overactive thyroid hormone production by destroying follicular cells. - Diagnostic imaging of thyroid tissue: enables visualization of functional thyroid tissue and metastatic disease through gamma emission imaging.

Sodium Iodide I-131 may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea: mild gastrointestinal upset occurring shortly after dosing. - Dry mouth: reduced salivary flow due to radiation of salivary glands. - Taste alteration: transient metallic or bitter taste sensation. - Sialadenitis: inflammation of salivary glands causing discomfort.

Serious or Rare Side Effects: - Bone marrow suppression: decreased blood cell counts leading to infection risk. - Severe hypothyroidism: excessive loss of thyroid function requiring hormone replacement. - Pulmonary fibrosis: rare lung tissue scarring after high cumulative doses. - Allergic reaction: rash, itching, or anaphylaxis in sensitive individuals.

Prior to prescribing Sodium Iodide I-131, several safety considerations should be evaluated.

- Pregnancy: avoid use unless benefits outweigh potential fetal radiation exposure. - Breastfeeding: discontinue nursing as the drug can be secreted in milk. - Renal function: assess kidney performance because excretion is renal. - Thyroid status: confirm indication and baseline thyroid hormone levels. - Radiation safety: implement protective measures for patients and staff to limit exposure. - Store at ambient temperature: keep in original container, protect from moisture and light.

Sodium Iodide I-131 can interact with other medications that affect thyroid function or radiation response.

Major Interactions (Avoid): - Antithyroid drugs (e.g., methimazole): may block iodine uptake, reducing efficacy. - Thyroid hormone replacement therapy: can diminish therapeutic effect if dosing is not adjusted. - Lithium: interferes with thyroid iodine handling, potentially altering treatment outcome.

Moderate Interactions (Monitor Closely): - Amiodarone: high iodine content may affect radioiodine distribution. - Potassium iodide: competitive inhibition of iodine uptake. - Chemotherapy agents: additive risk of bone marrow suppression.
