Displaying 1 results of Simethicone Stable Isotopes Simethicone stable isotopes are a form of simethicone, a medication used to treat symptoms of excess gas in the digestive tract. These isotopes have a stable molecular structure, meaning they do not decay over time. They are commonly used in medical research and drug development as a tool for studying the absorption and elimination of simethicone in the body. Simethicone stable isotopes provide a valuable resource for scientists seeking to gain a better understanding of this important medication and its effects on human physiology.
