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. There is a lack of evidence that simeticone is effective for this use.

Efficacy has not been fully established that simeticone is useful to treat colic in babies, and it is not recommended for this purpose, however evidence is sparse. In 2017, a real world evidence study in the United Kingdom, on simeticone based Infacol, suggested that it had helped infant colic in some cases.

There are no known side effects of simeticone.

Pharmacology

Simeticone is an anti-foaming agent that decreases the surface tension of gas bubbles, causing them to combine into larger bubbles in the digestive tract. Simeticone does not reduce or prevent the formation of gas.

Chemistry

The chemical name for simeticone is α-(trimethylsilyl)-ω-methylpoly[oxy(dimethylsilylene)], mixture with silicon dioxide.

Society and culture

The INN name is "simeticone", which was added to the INN recommended list in 1999.

Simeticone is marketed under many brand names and in many combination drugs; it is also marketed as a veterinary drug.
