Displaying 11 results of Enalapril Stable Isotopes Enalapril stable isotopes are isotopes of the drug enalapril that have a stable atomic nucleus and do not decay over time. These isotopes are used in pharmacokinetic studies to track the movement of enalapril through the body and to determine its metabolic fate. Enalapril is an angiotensin-converting enzyme (ACE) inhibitor that is used to treat hypertension and heart failure. The use of stable isotopes allows for precise measurement of drug metabolism and clearance rates, which can aid in drug development and optimization.
