Displaying 4 results of Ranitidine Stable Isotopes Ranitidine stable isotopes are a type of isotopic labeling technique used in medical research and drug development. These isotopes, such as carbon-13 and nitrogen-15, are incorporated into the molecular structure of ranitidine, a medication used to treat acid reflux and ulcers. By using these stable isotopes, researchers can track the metabolic fate of ranitidine in the body and better understand its pharmacokinetics and pharmacodynamics. This information can help optimize drug dosing and improve patient outcomes.
