8.5 Geriatric Use

Clinical studies of VARIBAR THIN LIQUID did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.


VARIBAR THIN LIQUID (barium sulfate) is a radiographic contrast agent that is supplied as a white to lightly colored powder for suspension (81% w/w) with an apple aroma for oral administration. The active ingredient barium sulfate is designated chemically as BaSO4 with a molecular weight of 233.4 g/mol, a density of 4.5 g/cm3 , and the following chemical structure:

Barium Sulfate Chemical Structure

VARIBAR THIN LIQUID has a viscosity of <15 cPs when reconstituted and contains the following excipients: carboxymethylcellulose sodium, citric acid, maltodextrin, natural and artificial apple flavor, polysorbate 80, saccharin sodium, simethicone, sodium citrate, sorbitol and xylitol.


12.1 Mechanism of Action

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

12.2 Pharmacodynamics

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

12.3 Pharmacokinetics

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


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No animal studies have been performed to evaluate the carcinogenic potential of barium sulfate or potential effects on fertility.


16.1 How Supplied

VARIBAR THIN LIQUID is supplied as a white to lightly colored powder in a multiple-dose polyethylene bottle containing 120 grams of barium sulfate (81% w/w).

Provided as: 24 x 148 g bottles (NDC 32909-105-10)
