Microtrast

Barium sulfate, the active ingredient in Microtrast, is a contrast media presented as an oral suspension for oral use. It creates radiopaque contrast for X‑ray imaging of the gastrointestinal tract, facilitating diagnostic procedures such as barium swallow, barium meal and barium enema in patients requiring gastrointestinal evaluation.

GNH USA supplies Microtrast as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable sourcing for diagnostic imaging agents across multiple regions.

Microtrast, a barium sulfate‑based oral contrast agent, is used for imaging of the gastrointestinal tract. - Barium swallow: Enables visualization of the esophagus and upper GI tract during fluoroscopic examination. - Barium meal (upper GI series): Provides contrast for assessment of the stomach and duodenum. - Barium enema: Supplies radiopaque coating for evaluation of the colon and rectum.

Adverse reactions are generally related to the gastrointestinal tract and the physical properties of the suspension.

Common Side Effects: - Nausea: Mild to moderate feeling of queasiness after ingestion. - Abdominal discomfort: Cramping or bloating in the stomach or intestines. - Constipation: Difficulty passing stool due to the dense suspension. - Taste disturbance: Unpleasant metallic or chalky taste.

Serious or Rare Side Effects: - Aspiration pneumonia: Inhalation of the suspension into the lungs. - Severe allergic reaction: Hives, swelling, or anaphylaxis. - Bowel obstruction: Rare blockage caused by the contrast material. - Perforation risk: Potential gut wall injury in patients with pre‑existing lesions.

Prior assessment and careful handling reduce the risk of complications. - GI obstruction: Evaluate for known strictures or recent surgery before administration. - Hypersensitivity: Confirm no known allergy to barium sulfate or related compounds. - Hydration: Encourage adequate fluid intake to facilitate passage of the contrast. - Pregnancy: Use only if clearly needed, as safety data are limited. - Storage: Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Barium sulfate can affect the absorption of certain oral medications and diagnostic agents.

Major Interactions (Avoid): - Tetracycline antibiotics: Chelation reduces antibiotic absorption. - Fluoroquinolone antibiotics: Barium may bind and diminish drug bioavailability. - Levothyroxine: Concurrent intake can lower thyroid hormone absorption.

Moderate Interactions (Monitor Closely): - Iron supplements: May form insoluble complexes, decreasing iron uptake. - Calcium-containing antacids: Potential reduction in absorption of both agents. - Radioactive iodine studies: Barium can interfere with thyroid imaging results.
