Microtrast (Barium Sulfate)

Barium sulfate, the active ingredient in Microtrast, is a contrast media presented as an oral preparation for oral use. It provides radiopacity to visualize the gastrointestinal tract during X‑ray examinations and is prescribed for patients requiring diagnostic imaging of the esophagus, stomach, and intestines.

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

Microtrast is used in gastrointestinal radiographic procedures to enhance X‑ray visualization of the digestive tract.

- Barium swallow: enables clear imaging of the esophagus for assessment of motility and structural abnormalities. - Barium meal: provides detailed visualization of the stomach and duodenum for evaluation of ulcers, tumors, and anatomical disorders. - Small bowel follow‑through: outlines the entire small intestine to detect strictures, malabsorption, or inflammatory disease. - Diagnostic imaging of the gastrointestinal tract: facilitates comprehensive radiographic assessment of the GI tract in various clinical settings.

Microtrast may cause transient gastrointestinal reactions and, rarely, severe adverse events.

Common Side Effects: - Nausea: mild to moderate feeling of queasiness after ingestion. - Abdominal cramping: intermittent discomfort during bowel coating. - Constipation: temporary difficulty passing stool. - Taste alteration: metallic or chalky sensation in the mouth. - Mild diarrhea: loose stools that resolve spontaneously.

Serious or Rare Side Effects: - Allergic reaction: rash, itching, or anaphylaxis in hypersensitive individuals. - Aspiration: inhalation of the suspension leading to respiratory compromise. - Bowel obstruction: rare blockage due to excessive coating. - Severe constipation: prolonged impaction requiring medical intervention. - Gastrointestinal perforation: rare tearing of the GI wall, a medical emergency.

Before administering Microtrast, consider the following safety measures.

- Assess hypersensitivity: verify no known allergy to barium sulfate. - Confirm swallowing ability: ensure the patient can safely ingest the oral preparation. - Avoid in suspected perforation: do not use if gastrointestinal perforation is suspected. - Pregnancy caution: weigh risks and benefits, as safety in pregnancy is unknown. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Microtrast may interact with other agents that affect gastrointestinal function or radiographic interpretation.

Major Interactions (Avoid): - Oral anticoagulants: increased risk of gastrointestinal bleeding. - Concurrent high‑density contrast agents: cumulative radiopacity may obscure imaging.

Moderate Interactions (Monitor Closely): - Antacids: may alter taste perception of the suspension. - Prokinetic drugs: can change transit time, affecting coating uniformity. - Iron supplements: may cause darkening of stool, potentially confusing image interpretation.
