Rarely, oral barium sulfate suspensions may cause constipation or intestinal obstruction due to impaction in the colon. Cramping from distention of the intestine by barium sulfate suspensions or diarrhea may also occur. Retention of barium sulfate in the appendix has reportedly caused appendicitis. Barium sulfate fecaliths reported can lead to obstruction, intussusception, ulceration, or even intestinal perforation and may rarely require surgical removal. ... Aspiration of large amt may cause pneumonitis or nodular granulomas of interstitial lung tissues and lymph nodes; asphyxiation and death have occurred in one patient.

Users must be certain that barium sulfate is not contaminated by sol barium salts. A convenient test is to shake up a portion with water and, to the clear supernatant portion, add a small amt of a soln of magnesium sulfate in water. Appearance of a precipitate indicates the presence of a sol barium salt.

Barium sulfate is a radiographic contrast agent indicated for use in computed tomography (CT) of the abdomen to delineate the gastrointestinal (GI) tract in adult and pediatric patients.
FDA Label
Barium sulfate increases the absorption of x-rays as they are passed throughout the body, delineating body structures, in which barium sulfate is localized. This allows for the clear visualization of normal organs/defect in normal anatomy.
Contrast Media
Substances used to allow enhanced visualization of tissues. (See all compounds classified as Contrast Media.)
Absorption
Barium sulfate is not absorbed following oral or rectal administration with a normal gastrointestinal tract. In patients with a normal GI tract, barium sulfate is normally excreted within 24 hr after oral ingestion. Post rectal administration of barium sulfate suspensions, the drug is generally excreted when the enema is released. Some barium may remain in the colon for several weeks, however, and eventually clears, especially in patients with impaired intestinal peristalsis. It is difficult to quantify the uptake of ingested barium because of a number of factors affect its absorption. The presence of sulfate in food can cause the precipitation of barium sulfate. The following is the approximate time to peak opacification of organs by barium sulfate in a healthy GI tract: Esophagus, stomach, and duodenum uptake of barium sulfate occurs almost immediately after oral administration. Small intestine uptake is dependent on gastric emptying rate and viscosity of the preparation; it may be delayed 15-90 minutes post ingestion. Small intestine (enteroclysis studies) uptake is immediate, following direct instillation. Colon and distal small intestine uptake are dependent on patient positioning. Hydrostatic pressure also determines the rate and degree of opacification.
Route of Elimination
Barium sulfate is excreted unchanged in the feces.
Clearance
The rate of excretion of barium sulfate is dependent on the route of administration and the status of peristaltic activity and motility of the gastrointestinal tract.

In an extensive study, temperature and pulse rate measurements were taken as an indication of an acute inflammatory response for 291 humans administered a single unstated dose of a 50% w/v barium sulfate suspension for bronchographic purposes. The method of administration was unstated, but the suspension was presumed to have been instilled into the trachea and then blown into the lungs. In 154 patients, there was radiological evidence of the presence of barium sulfate in the bronchial tree at the time of the last available X-ray (various time points ranging from < 1 week to > 1 year after administration); in 135 patients, on the other hand, there was no radiological evidence of residual barium sulfate in the lungs 1 year after bronchography. Forty-one of these patients exhibited complete elimination of the barium sulfate from the lungs within 1 week; it was stated that in some of these patients, this clearance occurred within 24 hr.

After inhalation exposure of rats to a BaSO4 aerosol at 40 mg/cu m, 5 hr daily for 2 months, lymphatic transport was slight. The skeletal concentration of Ba was 0.8-1.5 mg/g dry substance (10-100 times the pulmonary concentration). Skeletal uptake decreased somewhat with advancing age.

Barium sulfate is poorly water soluble and shows negligible levels of absorption from the gastrointestinal tract following both oral or rectal administration. In healthy subjects, orally administered barium sulfate is generally excreted within 24 hours. Rectally administered barium sulfate is eliminated with clearance of the enema.
The in vivo solubility in rats of barium chloride, barium carbonate, barium sulfate, and barium fused in clay /was studied/. The chloride and the carbonate disappeared rapidly from the injection site. The sulfate dissolved more slowly; a half-life of 26 days was calculated. The fused clay was largely retained, the half-life being calculated as 1390 days.

Barium sulfate is a heavy metal with a high atomic number (Z=56) and a K shell binding energy (K-edge of 37.4 keV) very close to that of most diagnostic x-ray beams. Due to these characteristics, barium is an ideal medium for the absorption of x-rays. Barium sulfate is essentially not absorbed from the GI tract nor metabolized in the body. Barium sulfate is used to fill the gastrointestinal tract lumen or to coat the mucosal surface and is administered orally, rectally, or instilled into an enterostomy tube or catheter,. Barium sulfate enhances delineation of the GI tract. The barium suspension covers the mucosal surface of the GI tract, allowing its shape, distensibility, motion, integrity, continuity, location within the torso, relationship to other organs to be closely examined. Various abnormalities, such as benign or malignant tumors, ulcers, strictures, diverticula, inflammation or infection, altered motility, displacement and other pathology can thereby be identified,. At lower concentrations (higher dilution), barium enhances the conspicuity of the GI tract to differentiate the GI tract from various abdominal organs in computed tomography examinations (CT scans) of the abdomen. Improved delineation of the gastrointestinal tract lumen and mucosa may be reached by contrast provided by gas (by the addition of bicarbonate or gas-filled balloons) in addition to the barium. This is known as a _double-contrast procedure_. Osmotically active agents (for example, sorbitol) are also used to induce fluid accumulation and distension of the GI system to enhance visualization.
