Participants were evaluated during five visits at 28-day intervals.Results: The mean age was 55.5 years in the SNB and 58.4 years in the DRASB + bisoprolol group (p=NS). Significant office BP reductions were observed in both groups. SNB group, SBP decreased from 174.5± 21.0 to 127.0± 14.74 mmHg (p< 0.0001), and DBP decreased from 105.3± 15.5 to 78.11± 9.28 mmHg (p< 0.0001). DRASB group, SBP decreased from 178.4± 21.08 to 134.4 ± 23.25 mmHg (p< 0.0001) and DBP decreased from 102.7± 11.07 to 77.33± 13.75 mmHg (p< 0.0001). Ambulatory blood pressure monitoring (ABPM) showed also significant SBP and DBP reductions in both groups (p< 0.0001).Conclusion: In patients with RHTN adherent to treatment, SNB and DRASB plus bisoprolol showed excellent therapeutic efficacy, although SNB was associated with earlier SBP reduction.Keywords: resistant hypertension, natriuretic agents, dual blockade of the renin-angiotensin system, bisoprolol
