Introduction

Simethicone is an over-the-counter product used to treat gas and to reduce bloating. It is a synthetic organic silicone compound that helps break gas bubbles and improves digestive tract motility. It is often referred to as an “anti-foaming agent” due to its ability to reduce surface tension of gas bubbles.

Uses

Simethicone is used to treat gas and to reduce bloating in adults, as well as children two years of age or older. It is also effective at preventing gas during air travel. It may also be used in people with gastrointestinal problems such as irritable bowel syndrome, gastroesophageal reflux disease, and pancreatitis.

Mechanism of Action

Simethicone works by changing the surface tension of gas bubbles in the stomach and intestines, reducing the size of the bubbles and allowing them to pass. This reduces the amount of gas present in the digestive tract and relieves and prevents bloating. Simethicone does not actually absorb gas, but rather works by forming a protective coating around gas bubbles to enable their easier passage from the body.
