Antithrombotic drugs are widely used to prevent thrombotic events in patients with cardiovascular diseases. However, they all carry varying degrees of bleeding risk. Currently, there are no approved reversal agents for antiplatelet medications, which limits their further clinical application and poses challenges in managing bleeding complications. In this proof-of-concept study, we explore the feasibility of a reversal agent system using ticagrelor and a corresponding liposome-based antidote. Specifically, we developed an azide-functionalized ticagrelor derivative (Tic-N
