Effects on repetitive 24-hour ambulatory blood pressure in subjects with type II diabetes randomized to liraglutide or glimepiride treatment both in combination with metformin: a randomized open parallel-group study

摘要

In this post hoc study, we aimed to investigate liraglutide treatment on repetitive 24-hour blood pressure (BP) in patients with type II diabetes. Sixty-two individuals with type II diabetes (45 males) were randomized to 1.8 mg liraglutide once daily or 4 mg glimepiride together with 1 g metformin twice daily. Ambulatory 24-hour systolic and diastolic blood pressure (sBP/ dBP) was repetitively measured at baseline, 2 weeks, and 18 weeks. Outcomes were evaluated as treatment change from baseline, 2 weeks, and 18 weeks. Baseline clinical characteristics of liraglutide (n = 33) and glimepiride (n = 29) groups were well matched. No statistically significant difference in 24-hour sBP/dBP between three time periods and groups was observed. There was no treatment change for 24-hour sBP at week 2 or after week 18. There was a transient treatment change in 24-hour dBP in the liraglutide group at week 2 (3.2 +/- 5.4 vs. -1.2 +/- 4.5 mm Hg, P .01). A treatment change in 24-hour heart rate at week 2 (4.9 +/- 6.8 vs. 1.0 +/- 6.0 bpm, P = .03) and at week 18 (5.9 +/- 7.8 vs. 0.2 +/- 6.3 bpm, P .01) was observed in the liraglutide group. In conclusion, liraglutide treatment did not lower BP. However, a small diurnal variation in dBP without affecting BP variability or nocturnal BP dipping was observed.
