Indications & Uses

Flatulence, abdominal distention, fullness, gas and windy colic: Flatulex is an excellent and effective antiflatulent, used to relieve the painful symptoms of excess gas in the digestive tract. Such gas is often caused by swallowing air or eating certain foods that disagree with the digestion. Flatulex drop is especially suited for infants, acting in the stomach and intestines to help release gas more easily through belching or passing flatus. In large bowel preparation, adding Flatulex to a polyethylene glycol bowel preparation produces symptomatic improvement prior to investigation. It also has an anecdotal use as an antifoaming agent in managing accidental ingestion of foaming detergents.

Pharmacology

Simethicone is used as an antiflatulent to relieve the symptoms people usually call gas, including bloating, pressure and fullness in the upper stomach. Its clinical use rests on its antifoaming properties, which is how it works. Simethicone breaks up and stops gas pockets that are held together by mucus in the digestive tract, so the gas can move through more easily.

Simeticone acts in the stomach and intestines. It changes the surface tension of gas bubbles, which lets them join together. Once they join, the gas is released and is easier to get rid of, either by belching or by passing wind.

Simeticone also helps remove gas from the digestive tract, and it can be used to ease gas pain after an operation. Before a gastroscopy, it can be given to improve visualization, and before an X-ray of the intestine, it can reduce gas shadows.
