The secondary outcomes will evaluate treatment safety and tolerability, biochemical changes, evaluation of renal function and recognition of hypotension (ambulatory BP monitoring (ABPM)). stabilize, or acting on the effects of the renin-angiotensin-aldosterone system (RAAS) within the kidney. Methods/design This is a randomized, open-label, medical trial is designed to compare sequential nephron blockade and its contribution to the intravascular volume component with dual blockade of the RAAS plus bisoprolol and the importance of serum renin in keeping BP levels. The trial offers two arms: sequential nephron blockade versus dual blockade of the RAAS (with an angiotensin transforming enzyme (ACE) inhibitor plus a beta-blocker) both added-on to a thiazide diuretic, a calcium-channel blocker and an angiotensin receptor-1 blocker (ARB). Sequential nephron blockade is made up inside a progressive increase in sodium depletion using a thiazide diuretic, an aldosterone-receptor blocker, furosemide and, finally, amiloride. On the other hand, the dual blockade of the RAAS consists of the progressive addition of an ACE inhibitor until the maximum dose and then the administration of a beta-blocker until the maximum dose. The primary results will become reductions in the systolic BP, diastolic BP, mean BP and pulse pressure (PP) after 20?weeks of treatment. The secondary results will evaluate treatment security and tolerability, biochemical changes, evaluation of renal function and acknowledgement of hypotension (ambulatory BP monitoring (ABPM)). The sample size was determined presuming an alpha error of 5% to reject the null hypothesis having a statistical power of 80% providing a total of 40 individuals per group. Conversation In recent years, the cost of resistant hypertension (RH) treatment offers increased. Thus, identifying the contribution of intravascular volume and serum renin in keeping BP levels could help tailor more effective hypertension treatment, whether by acting on the control of intravascular volume or sodium balance, or by acting on the effects of the RAAS within the kidney.
