Effects of Sodium Intake on (PK/PD) Relationship of a Single Dose of a Renin Angiotensin System-Blocker
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The impact of sodium intake on plasma drug concentrations has previously been reported in the literature for verapamil and quinidine but, to the investigators' knowledge, never with renin-angiotensin system blockers such as AT1R antagonists and angiotensin converting enzyme inhibitors.
The impact of sodium intake on plasma drug concentrations concentrations obtained after a single oral dose of RAS blocking drugs (ramipril 10 mg, valsartan 160 mg, candesartan 8 mg) or a blocker as control (ATENOLOL 50 mg) will be compared in healthy normotensive men randomly assigned to a 6-day replated-sodium diet or a sodium depletion.
Effects of Sodium Intake on Pharmacokinetic/Pharmacodynamic Relationship of a Single Dose of a Renin Angiotensin System-Blocker, or a Beta-Blocker in Normotensive Sodium-Depleted or Replated Volunteers in a Cross-Over Study
