Micropaque Ct (Barium Sulfate)

Micropaque Ct is a radiographic contrast agent used for gastrointestinal imaging procedures.

• Barium swallow: enhances visualization of the esophagus during swallowing studies.
• Barium meal: provides contrast for assessment of stomach and duodenal anatomy.
• CT imaging of gastrointestinal tract: improves delineation of bowel loops in computed tomography examinations.

• Barium sulfate contains a high atomic number element that strongly attenuates X‑ray photons. When the powder is mixed into a suspension and ingested, it coats the mucosal surface of the gastrointestinal lumen, creating a radiopaque lining that appears white on X‑ray, fluoroscopy, or CT images, thereby highlighting the shape and integrity of the GI tract for diagnostic evaluation.

Adverse reactions may occur following oral administration of Micropaque Ct.

Common Side Effects

• Nausea: mild to moderate feeling of queasiness.
• Abdominal discomfort: cramping or fullness in the stomach.
• Constipation: reduced bowel movements after the study.
• Diarrhoea: loose stools in some patients.
• Mild vomiting: occasional emesis shortly after ingestion.
• Metallic taste: transient metallic sensation in the mouth.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, or anaphylaxis requiring immediate medical attention.
• Aspiration pneumonia: risk if the suspension is inhaled instead of swallowed.
• Severe constipation leading to bowel obstruction.
• Gastrointestinal perforation: especially in patients with existing ulcers or strictures.
• Electrolyte imbalance: rare disturbances due to fluid shifts.
• Severe hypersensitivity: bronchospasm or angioedema.

Prior to using Micropaque Ct, clinicians should consider several safety measures.

• Assess for known GI obstruction: avoid use in patients with suspected or confirmed bowel blockage.
• Screen for hypersensitivity: discontinue immediately if an allergic reaction develops.
• Consider recent bowel surgery: use with caution in postoperative patients.
• Avoid in patients with severe constipation or ileus: risk of worsening obstruction.
• Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Micropaque Ct may interact with other agents that affect imaging quality or gastrointestinal function.

Major Interactions (Avoid)

• Concurrent use of oral iodinated contrast agents: may increase overall radiodensity and compromise image interpretation.
• Antacids containing aluminum or magnesium: can bind barium and reduce contrast efficacy.

Moderate Interactions (Monitor Closely)

• Proton pump inhibitors: may alter gastric pH, affecting barium coating.
• Laxatives: may change transit time and impact image quality.
• Diuretics: potential electrolyte shifts if severe dehydration occurs.
