Metopirone

Metyrapone, the active ingredient in Metopirone, is a 11‑beta‑hydroxylase inhibitor presented as an oral tablet for oral use. It is used in the diagnostic testing of adrenal insufficiency and in the treatment of Cushing's syndrome in adults.

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

Metopirone (metyrapone) is employed in endocrine diagnostics and therapy related to cortisol production.

- Adrenal insufficiency (diagnostic testing): helps assess adrenal reserve by stimulating ACTH response. - Cushing's syndrome (treatment): reduces cortisol synthesis in patients with endogenous hypercortisolism. - ACTH stimulation test (diagnostic): used to evaluate pituitary‑adrenal axis function.

Metyrapone may cause a range of adverse reactions, some of which are common and others that are serious or rare.

Common Side Effects: - Nausea - Dizziness - Headache - Fatigue

Serious or Rare Side Effects: - Adrenal insufficiency - Severe hypotension - Allergic reaction (e.g., rash, angioedema)

When using Metopirone, several safety considerations should be observed.

- Monitor cortisol levels: regular testing to avoid adrenal crisis. - Assess electrolyte balance: watch for hyponatremia and potassium shifts. - Avoid abrupt discontinuation: taper under medical supervision. - Use caution in hepatic impairment: adjust monitoring. - Store at ambient temperature: keep in the original pack, protect from moisture and light.

Metyrapone can interact with other medications, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Ketoconazole: additive inhibition of cortisol synthesis may cause severe adrenal suppression. - Mifepristone: opposing effects on glucocorticoid pathways may reduce efficacy.

Moderate Interactions (Monitor Closely): - Carbamazepine: enzyme induction may reduce metyrapone levels. - Rifampin: may increase metabolism, lowering effect. - Oral contraceptives: may alter hormone levels, monitor closely.
