Montek (Sodium Molybdate (99mo))

Montek (sodium molybdate) is provided primarily for non‑therapeutic applications and investigational research.

• No approved clinical indication: The product is not marketed for treatment of a specific disease.
• Research use only: Utilized in laboratory studies of molybdenum metabolism and enzyme function.
• Experimental diagnostic imaging: Explored as a contrast agent in ocular imaging studies.

• Sodium molybdate delivers molybdenum ions that act as essential cofactors for several oxidoreductase enzymes, including sulfite oxidase, xanthine oxidase and aldehyde oxidase. By supplying molybdenum, it supports the catalytic activity of these enzymes involved in sulfur and purine metabolism, which can be relevant in biochemical and pharmacological investigations.

Sodium molybdate may be associated with adverse reactions when administered intravenously or ocularly.

Common Side Effects

• Injection site pain: mild discomfort at the administration site.
• Nausea: transient feeling of queasiness.
• Headache: mild to moderate headache.
• Transient visual disturbance: temporary changes in vision after ocular administration.
• Mild flushing: temporary reddening of skin.

Serious or Rare Side Effects

• Anaphylactic reaction: severe allergic response requiring immediate medical attention.
• Hypotension: sudden drop in blood pressure.
• Severe ocular inflammation: significant inflammation of the eye.
• Renal impairment: reduced kidney function in susceptible individuals.
• Hemolysis: destruction of red blood cells.
• Thrombocytopenia: low platelet count.

When handling Montek, consider the following precautions:

• Contraindication: Do not use in patients with known hypersensitivity to molybdenum compounds.
• Pregnancy: Avoid use unless clearly needed; safety not established.
• Breastfeeding: Use with caution; molybdenum may be excreted in milk.
• Renal function: Monitor patients with impaired kidney function.
• Drug interactions: Review concomitant use of other trace‑element supplements.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Potential drug interactions with sodium molybdate should be assessed.

Major Interactions (Avoid)

• Copper supplements: may exacerbate copper deficiency.
• High‑dose zinc: can interfere with molybdenum absorption.
• Certain antibiotics (e.g., tetracyclines): may chelate molybdenum.

Moderate Interactions (Monitor Closely)

• Vitamin B12: high doses may affect molybdenum metabolism.
• Diuretics: may alter renal excretion of molybdenum.
• Antacids containing aluminum or magnesium: could affect absorption.
