    Abstract

    The efficacy of olmesartan on fibrinolytic capacity has not been studied yet. Therefore, the aim of the present study was to investigate the efficacy of olmesartan on hemostatic/fibrinolytic status by measuring plasma level of plasminogen activator inhibitor-1 (PAI-1) and soluble thrombomodulin levels in patients with hypertension. Forty-two consecutive, newly diagnosed (25 women and 17 men with a mean age of 48 ± 8 years) patients with untreated essential hypertension were included in the study. Olmesartan medoxomil (20 mg/day) was started and the patients were followed up for 6 months. Baseline biochemical variables, thrombomodulin, and PAI-1 levels were compared with the levels of these variables measured at the end of the 6-month follow-up period. After 6 months of treatment with olmesartan medoxomil, there was a significant reduction in systolic and diastolic blood pressure (from 159.5 ± 10.9 to 134.6 ± 12.7 mmHg and from 98.0 ± 6.3 to 83.9 ± 7.0 mmHg, respectively). Mean plasma PAI-1 and thrombomodulin levels were also significantly decreased (59.73 ± 41.91 vs. 48.60 ± 33.65 ng/ml, P = 0.001 and 8.09 ± 2.29 vs. 6.92 ± 1.42 μg/l, P < 0.001, respectively). Olmesartan medoxomil decreased plasma PAI-1 and thrombomodulin levels after 6 months of therapy, indicating a favorable effect on fibrinolytic capacity in patients with essential hypertension.
