Barium sulfate is excreted unchanged in the feces. ... In patients with a normal GI tract, barium sulfate is generally excreted within 24 hr after oral admin of suspensions of the drug. ... After rectal admin of barium sulfate suspensions, the drug is generally excreted when enema is expelled; however, some may remain in the colon for several weeks.
Radiography, gastrointestinal—Oral or rectal barium sulfate suspension, and the oral tablet, are indicated for radiographic examination of the gastrointestinal tract. Barium sulfate suspension, when administered orally, provides contrast to help detect and evaluate abnormalities of the esophagus, the stomach, and/or the small intestine.
Barium sulfate. Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it.
But in this case, there is no term for the concentration of the solid barium sulfate. This is a heterogeneous equilibrium, one which contains substances in more than one state. In a heterogeneous equilibrium, concentration terms for solids are left out of the expression.

Barium sulfate scale (barite) in oil fields can be precipi-tated easily on the basis of already available information relating to thermodynamic condition and the kinetics of pre-cipitation [20, 25]. Barium sulfate solubility increased with temperature increase, with increase ionic strength of brine, and with pressure.

Uniform opacification is important for consistent visualization. VARIBAR products offer a standard 40% w/v ratio of barium sulfate concentration across the product line, helping to ensure a uniform density in each product. In turn, you get the same visualization from each swallowing event, test after test, no matter what viscosity level.
Changes in viscosity are dependent on the concentration of barium in the solution: Dantas et al. reported that a 1.40-g/ml thin-liquid solution (equivalent to a 140 % w/v solution), made with E-Z-HD barium sulfate and distilled water, had a viscosity of 200 cP, but that a 2.50-g/ml thin-liquid solution (equivalent to a 250 % w/v solution) made with the same powder had a viscosity of 300 cP.
READI-CAT ® 2 is a barium sulfate suspension 2.1% w/v, 2.0% w/w for oral administration. Each 100 mL contains 2.1 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 BaSO 4.
