Silicones are widely used in the pharmaceutical industry as they are biocompatible and act as excipients, antifoaming agents, and active components in pharmaceutical aids. They are used to treat symptoms of stomach acid, such as upset stomach, heartburn, and acid indigestion, as well as the painful symptoms of gas in the stomach and intestines. As excipients, silicones aid in the formulation of pharmaceuticals and are essential for the distribution of active medicines within the body.

Most antacid products and gastro-intestinal medications use various amounts of Simethicone USP and IP emulsions, while topical medicinal treatments contain Dimethicone as an excipient.
