 BARIUM SULFATE BRAND NAME:-  BARICON , BAROTRACT, BAROCAT etc  BARIUM SULFATE is a contrast agent used for CT scans of the gastrointestinal tract, & is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water.  PHARMACODYNAMIC:- Barium sulfate is an insoluble material which, because of its density, provides a positive contrast during x-ray examination. Barium sulfate is an inert radiopaque material which is not absorbed or metabolized and is eliminated intact from the body in a manner similar to other non-absorbed inorganic materials. Excretion rate is a function of gastrointestinal transit time.  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 .  MECHANISM OF ACTION:- Barium sulfate is in a cla...
