Natpar (Parathyroid Hormone)

Parathyroid Hormone, the active ingredient in Natpar, is a hormone presented as an injectable solution for subcutaneous use. It treats hypoparathyroidism by restoring physiologic calcium regulation in patients with deficient endogenous PTH.

GNH USA supplies Natpar as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres and pharmacies worldwide, adhering to EU manufacturing standards and providing reliable cold‑chain logistics for injectable biologics. The company ensures product integrity through rigorous quality control and regulatory compliance.

Natpar is used to manage disorders of calcium metabolism, primarily hypoparathyroidism.

Hypoparathyroidism: restores serum calcium levels and reduces symptoms of hypocalcemia in patients with deficient endogenous PTH. Post‑surgical hypoparathyroidism: helps maintain calcium balance after thyroid or parathyroid surgery. Chronic hypoparathyroidism: provides long‑term calcium homeostasis for patients requiring ongoing hormone replacement.

Natpar may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Injection site pain or erythema - Nausea - Headache - Dizziness - Mild hypercalcemia - Fatigue

Serious or Rare Side Effects: - Severe hypercalcemia - Hypersensitivity reactions, including anaphylaxis - Osteosarcoma (rare) - Cardiovascular events such as arrhythmia - Acute renal failure - Severe hypotension

When prescribing Natpar, clinicians should observe several safety measures to minimize risk. - Monitor serum calcium: check levels regularly to avoid hypercalcemia. - Assess renal function: evaluate kidney status before and during therapy. - Evaluate for hyperparathyroidism: avoid use in patients with active hyperparathyroidism. - Use caution with vitamin D analogues: may increase calcium levels. - Avoid in known hypersensitivity: discontinue if allergic reaction occurs. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Natpar can interact with other agents that affect calcium balance or bone metabolism.

Major Interactions (Avoid): - Loop diuretics: may cause excessive calcium increase. - High‑dose vitamin D analogues: risk of severe hypercalcemia. - Bisphosphonates: may blunt therapeutic effect on bone.

Moderate Interactions (Monitor Closely): - Calcium supplements: require dose adjustment. - Magnesium supplements: can affect PTH activity. - Antacids containing aluminum or magnesium: may interfere with absorption. - Corticosteroids: may alter calcium metabolism.
