Anamorelin is a novel, orally active ghrelin receptor agonist that has potential therapeutic value in the treatment of cancer cachexia. However, during its synthesis and formulation process, impurities may be produced. These impurities can affect the purity, efficacy, and safety of the final drug product. Therefore, it is essential to identify, characterize, and control these impurities to ensure the quality of the drug. Various analytical techniques such as HPLC, LC-MS, and NMR are used for the detection and quantification of anamorelin impurities.
