Core Tip

Core tip: Whether a combination therapy with natriuretic and aquaretic drugs is more effective than conventional therapy with natriuretic drugs only for liver cirrhosis patients with ascites remains unclear. To clarify this, we compared the pharmacological effects of combination therapy with conventional therapy in cirrhotic ascites patients. Compared to a conventional therapy with only natriuretic drugs, a combination therapy with natriuretic and aquaretic drugs is more effective for patients with cirrhotic ascites.
