ABSTRACT
PURPOSE:
Head-to-head comparison of the blood pressure (BP) lowering effect of fimasartan versus valsartan, with olmesartan as a reference, on office blood pressure and ambulatory BP. PATIENTS ANDMETHODS:
Of the 369 randomly assigned patients in this study, 365 hypertensive patients were referred as the full analysis set and divided into 3 groups with a 331 ratio (fimasartan group 155, valsartan group 157, olmesartan group 53). After the 2-week single-blind placebo run-in period, initial standard doses of 60-mg fimasartan, 80-mg valsartan, and 10-mg olmesartan were administered for 2 weeks, then forcibly up-titrated higher doses (fimasartan 120 mg, valsartan 160 mg, olmesartan 20 mg) were given for 4 weeks. ABP was measured before and after the 6-week treatment. Primary endpoint was reduction of sitting office systolic BP (SiSBP) of fimasartan compared to valsartan after 6 weeks. Secondary endpoints were reduction of sitting office diastolic BP (SiDBP) and 24 hrs, day-time, and night-time mean systolic and diastolic ABP (ASBP, ADBP) after 6 weeks.RESULTS:
Patients' mean age was 58.34±7.68 years, and 289 patients were male (79.18%). After the 6-week treatment, SiSBP reduction of fimasartan and valsartan were -16.26±15.07 and -12.81±13.87 (p=0.0298) and SiDBP were -7.63±9.67 and -5.14±8.52 (p=0.0211). Reductions in 24 hrs mean ASBP were -15.22±13.33 and -9.45±12.37 (p=0.0009), and ADBPs were -8.74±7.55 and -5.98±7.85 (p=0.0140). Reductions of night-time ASBPs were -16.80±15.81 and -10.32±14.88 (p=0.0012), and those of night-time ADBPs were -8.89±9.93 and -5.55±9.70 (p=0.0152). Reduction of BP in olmesartan group did not demonstrate significant difference with fimasartan group in all end-points.CONCLUSION:
Fimasartan 120-mg treatment demonstrated superior efficacy in reduction of SiSBP, SiDBP, and 24 hrs ASBP and ADBP compared to valsartan 160 mg. Reduction of night-time ASBP from baseline was largest in fimasartan group, suggesting that fimasartan may be effective for recovering dipping pattern.
