ENTERO VU™ 24%
(barium sulfate) 24% Suspension

DESCRIPTION

ENTERO VU™ 24% Barium Sulfate Suspension (24% w/v, 20% w/w) is a barium sulfate suspension for oral administration. Each 100 mL contains 24 g barium sulfate. Barium sulfate, due to its high molecular density is opaque to x-rays and, therefore, acts as a positive contrast agent for radiographic studies. The active ingredient is barium sulfate and its structural formula is BaSO4. Barium sulfate occurs as a fine, white, odorless, tasteless, bulky powder which is free from grittiness. Its aqueous suspensions are neutral to litmus. It is practically insoluble in water, solutions of acids and alkalies, and organic solvents.

Inactive Ingredients : acacia, carrageenan, citric acid, methylcellulose, natural and artificial blueberry flavor, polysorbate 80, potassium chloride, potassium sorbate, purified water, saccharin sodium, simethicone emulsion, sodium benzoate, sodium citrate, sorbitol solution, and xanthan gum.

Side Effects & Drug Interactions

SIDE EFFECTS

The following adverse reactions have been identified from spontaneous reporting or clinical studies of barium sulfate administered orally. Because the reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to drug exposure:

  • Nausea, vomiting, diarrhea and abdominal cramping
  • Serious adverse reactions and fatalities include aspiration pneumonitis, barium sulfate impaction, intestinal perforation with consequent peritonitis and granuloma formation, vasovagal and syncopal episodes

DRUG INTERACTIONS

Overdosage & Contraindications

OVERDOSE

No Information Provided

CONTRAINDICATIONS

ENTERO VU 24% is contraindicated in patients with the following conditions:

  • known or suspected perforation of the GI tract
  • known obstruction of the GI tract
  • high risk of GI perforation such as those with a recent GI perforation, acute GI hemorrhage or ischemia, toxic megacolon, severe ileus, post GI surgery or biopsy, acute GI injury or burn, or recent radiotherapy to the pelvis
  • high risk of aspiration such as those with known or suspected tracheo-esophageal fistula or obtundation
  • known severe hypersensitivity to barium sulfate or any of the excipients of ENTERO VU 24%
Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

Due to its high atomic number, barium (the active ingredient in ENTERO VU 24%) is opaque to x-rays and therefore acts as a positive contrast agent for radiographic studies.

Pharmacodynamics

Barium sulfate is biologically inert and has no known pharmacological effects.

Pharmacokinetics

Under physiological conditions, barium sulfate passes through the gastrointestinal tract in an unchanged form and is absorbed only in small, pharmacologically insignificant amounts.

Medication Guide

PATIENT INFORMATION

After administration, advise patients to:

  • Maintain adequate hydration [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
  • Seek medical attention for worsening of constipation or slow gastrointestinal passage [see WARNINGS AND PRECAUTIONS].
  • Seek medical attention for any delayed onset of hypersensitivity: rash, urticaria, or respiratory difficulty [see WARNINGS AND PRECAUTIONS].
