Cаrdiаc glycоsides increаse the fоrce оf contraction of cardiac muscle cells. As the intracellular Ca++ concentration increases, the force of contraction increases. These drugs work by slowing down the function of the Na+/K+ pump. Intracellular Ca++ concentration is regulated by secondary active transport through a Na+/ Ca++antiporter. This means that the diffusion of Na+ down its concentration gradient into the cell provides the energy to transport Ca++ out of the cell (against its gradient). How would these drugs effect Ca++ movement out of the cell?
