摘要
Background: There are confusing data in literature regarding oral and sublingual captopril effects over blood pressure (BP) decrease. Objectives: In our study we compared oral and sublingual captopril effectiveness over BP decrease in patients admitted to our Emergency Department with hypertensive urgency. Methods: Our study was conducted from January 2012 to January 2013 in patients with hypertensive urgency. In this cross-sectional study after two initial BP measurements, patients were identified as eligible for the study. An initial electrocardiogram was obtained and blood samples were drawn. A total of 212 patients were accepted as eligible for the study, and 25 mg of captopril was randomly given orally or sublingually; BP was measured at 10, 30, and 60 min. We selected the patients to the groups consecutively. A 25% reduction of initial BP 1 h after initiation of the treatment was accepted as an accomplishment. A second 25 mg of captopril was given if the target of 25% reduction of BP was not reached after the first tablet. Intravenous drugs were administered to the patients resistant to the captopril and these patients were excluded from the study. Results: The 10-min systolic BP (SBP), diastolic BP, and mean BP (MBP) decrease was more prominent in the sublingual captopril group (p < 0.001). This decrease was statistically significant in the SBP and MBP at 30 min (p < 0.001), and no statistical difference was recorded at 60 min (p > 0.05). Conclusions: In our study, sublingual captopril was found to decrease BP more efficiently in the first 30 min, but this difference equalized at 60 min. (C) 2016 Elsevier Inc.
