Omecamtiv mecarbil is a selective cardiac myosin activator developed for the treatment of heart failure with reduced ejection fraction (HFrEF). It works by increasing cardiac contractility without increasing intracellular calcium concentrations or myocardial oxygen consumption. It has been assessed in clinical trials for chronic heart failure, but is not widely approved for routine use.
Pharmacokinetics
Pharmacokinetic parameters reported for healthy adult subjects after oral administration.
