Simeticone

Simeticone (INN), also known as simethicone (USAN), is an anti-foaming agent used to reduce bloating, discomfort or pain caused by excessive gas.
Medical uses
Simeticone is used to relieve the symptoms of excessive gas in the gastrointestinal tract, namely bloating, burping, and flatulence. While there is a lack of conclusive evidence that simeticone is effective for this use,⁣ studies have shown that it can relieve symptoms of functional dyspepsia and functional bloating.
It has not been fully established that simeticone is useful to treat colic in babies, and it is not recommended for this purpose. A study in the United Kingdom reported that according to parental perception simeticone helped infant colic in some cases.
Simeticone can also be used for suspected postoperative abdominal discomfort in infants.
Side effects
Simeticone does not have any serious side effects. Two uncommon side effects (occurring in 1 in 100 to 1 in 1,000 patients) are constipation and nausea.
Pharmacology
Simeticone is a non-systemic surfactant which decreases the surface tension of gas bubbles in the GI tract. This allows gas bubbles to leave the GI tract as flatulence or belching. Simeticone does not reduce or prevent the formation of gas. Its effectiveness has been shown in several in vitro studies.
Chemistry
Simethicone is a mixture of dimethicone and silicon dioxide.
