Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
