O-Desmethyl Mebeverine alcohol is primarily used as a metabolite in pharmacological studies to understand the metabolism and pharmacokinetics of mebeverine, a drug commonly prescribed for gastrointestinal disorders such as irritable bowel syndrome (IBS). Researchers analyze this compound to evaluate how mebeverine is processed in the body, providing insights into its efficacy and safety. Additionally, it serves as a reference standard in analytical laboratories for developing and validating methods to detect and quantify mebeverine and its metabolites in biological samples, such as blood or urine. This helps in monitoring drug levels in patients and ensuring compliance with prescribed dosages. Its role in metabolic studies contributes to optimizing therapeutic strategies for managing gastrointestinal conditions.
