Division of Medicinal Chemistry and Pharmacognosy, College of Pharmacy, The Ohio State University, Columbus, OH 43210, United States. Electronic address:

Na/K-ATPase (NKA) is a plasma membrane ion-transporting protein involved in the generation and maintenance of Na and K gradients across the cell membrane, which can produce a driving force for the secondary transport of metabolic substrates. NKA also regulates intracellular calcium that is responsible for modulating numerous cellular processes, while it interacts with many other proteins and functions as a signal transducer, with several signaling pathways being involved. Thus, NKA has become an important target for the treatment of human diseases.

Article Synopsis
  • Cardiogenic shock (CS) poses significant health risks, necessitating effective interventions to maintain blood pressure and tissue perfusion, while current treatments, like inotropes, can lead to serious side effects.
  • The SEISMiC study aims to evaluate the safety and effectiveness of istaroxime, a new drug that may improve blood flow without overstimulating adrenergic receptors, in patients at risk for CS.
  • This multinational, double-blind study involves patients with severe heart failure and aims to measure the drug's impact on blood pressure and other cardiac metrics over a 60-hour period, aiming to clarify istaroxime's potential benefits in managing pre-CS conditions.
