The overall hypothesis is that treatment with the SGLT2 inhibitor Ertugliflozin induces a differential regulation in interstitial fluid vs plasma volume, with more reduction of the volume from the interstitial fluid than from the circulating plasma volume, which results in Ertugliflozin inducing more potent congestion relief with minimal impact on blood volume and organ perfusion. Ertugliflozin reduces the levels of sodium and water from the skin and the interstitial tissue (which improves tissue congestion).
