Piriprost potassium salt is primarily used in research settings to study its effects on inflammatory processes and respiratory conditions. It acts as a leukotriene inhibitor, making it valuable in exploring treatments for asthma and other inflammatory diseases. Researchers utilize it to understand the mechanisms of airway inflammation and to develop potential therapeutic agents targeting leukotriene pathways. Its application in experimental models helps in evaluating its efficacy in reducing bronchoconstriction and inflammation, contributing to advancements in pulmonary medicine.
