Background: Angiotensin II receptor blockers (ARBs) play a key role in hypertension therapy. Recently, fimasartan, the ninth ARB, was developed, but its safety and efficacy have not been well established. Objective: The objective of this study was to determine whether age, sex, concomitant disease, and current antihypertensive medications affect the safety and efficacy of fimasartan in patients with arterial hypertension. Methods: This was a large-scale, open-label observational study to determine the safety and efficacy of fimasartan in patients with hypertension. Patients who were treated for more than 2 months with fimasartan (60 or 120 mg, once daily) were recruited, and the data were systematically collected using electronic case report forms. Written informed consent forms were obtained from all patients. Results: A total of 14,151 patients (50.7 % males; mean age 59 ± 12 years) were evaluated, of whom 37.9 % were never treated with fimasartan, 53.5 % were switched to fimasartan, and 8.5 % had fimasartan added to their treatment. Overall, fimasartan reduced systolic blood pressure (SBP) from 145.4 ± 18.1 to 126.8 ± 12.6 mmHg and diastolic blood pressure (DBP) from 88.7 ± 11.8 to 79.0 ± 8.7 mmHg (all p < 0.001). The pulse rate decreased from 74.4 ± 10.3 to 71.9 ± 9.2 beats/min in comparison with before treatment (p < 0.001). The reductions were similar between sexes, age groups, and patients with and without co-morbidities, and were not dependent on prior or concomitant treatment with other antihypertensive drugs. Adverse events were reported in 3.31 % (treatment-emergent) and 2.35 % (drug-related) of patients; there were no dose differences for adverse events. The most frequent adverse events were dizziness (1.55 %) and headache (0.52 %); other adverse events were rare. The responder rate (DBP to <90 mmHg or a reduction of ≥10 mmHg) and the goal rate (combined SBP/DBP <140/90 mmHg) were 85.0 and 75.6 %, respectively. Global drug compliance was rated as excellent, very good, good, and poor in 68.1, 26.9, 3.4, and 1.7 % of patients, respectively. Conclusion: The safety, efficacy, and compliance of fimasartan were found to be excellent in a large patient population that included patients potentially at higher risk for adverse events.
