OR-1896 is primarily used in pharmacological research due to its role as an active metabolite of levosimendan. It exhibits positive inotropic effects, making it valuable in studies focused on heart failure and cardiovascular diseases. Researchers utilize OR-1896 to understand its mechanisms in enhancing cardiac contractility and improving hemodynamics. Its application extends to exploring potential therapeutic benefits in patients with compromised heart function, particularly in chronic heart failure scenarios. Additionally, it is studied for its vasodilatory properties, which contribute to reducing cardiac workload and improving blood flow.
