Sacubitril/Valsartan in Resistant Hypertension

Worldwide, millions of people are affected by the arterial hypertension system (SAH), so that the presence of resistant hypertension (RH) significantly influences a high cardiovascular morbidity and mortality compared to those with controlled SAH, thus corroborating the need for the development of agents antihypertensive drugs with favorable efficacy and safety profiles. It is known that they are currently using the combined therapy recommended for this group of patients, among them, a significant portion of individuals with RH are unable to achieve the goal of BP control (>140/90 mmHg) even though in regular use, being subject to the greatest risk of cardiovascular outcomes and morbidity and mortality. Approved by the FDA for use in heart failure with reduced ejection fraction with beneficial effects on morbidity and mortality, identified in previous studies, the sacubitril/valsartan molecule (LCZ696) or Entresto® is a molecular complex composed of the sacubitril prodrug activated after ingestion in sacubitrilate - neprilysin inhibitor - associated with valsartan, an angiotensin II type-1 (AT1) receptor antagonist, with vasodilating action, capable of reducing BP, sympathetic tone, with antifibrotic and anti-hypertrophic effects, in addition to natriuresis and diuresis. Considering the knowledge gap to the benefits to LCZ696 in the control of blood pressure in resistant hypertension, the objective of the present study is to evaluate the efficacy (reduction of ambulatory systolic and diastolic blood pressure) and safety (adverse events, hospitalization and cardiovascular death) of the use of sacubitril/valsartan in comparison to the antihypertensive therapy recommended and optimized by the current guidelines, in patients diagnosed with RH, over12 weeks, through a randomized clinical trial.

Inclusion criteria

• Men or women, over 18;
• Diagnosed with resistant hypertension (using three or more antihypertensive agents of different classes - eg. angiotensin-converting enzyme inhibitor, angiotensin II receptor blocker, calcium channel blockers, loop and thiazide diuretics or potassium-sparing diuretics), at least 4 weeks before recruitment, with a BP that remains above the goal of 140/90 mmHg.
