Abstract
AIMS
The changes in patients' satisfaction with the treatment, medication adherence and unused drugs before and after switching from daily DPP-4 inhibitors to once-weekly trelagliptin administration were prospectively investigated in patients with type 2 diabetes.
METHODS
After excluding 46 patients who declined to switch from daily DPP-4 inhibitors, 79 subjects were included in the present study. The clinical parameters and results of questionnaire surveys regarding satisfaction with treatment as well as impressions of the amount of medicine/number of doses, medication adherence, and unused drug were examined at the baseline and 3 months after switching from daily DPP-4 inhibitors to trelagliptin in 75 patients with type 2 diabetes.
RESULTS
Although the value of HbA1c did not change (7.0% ± 0.5% to 7.0% ± 0.6%), the scores representing satisfaction with the treatment (25.2 ± 6.4 to 26.4 ± 6.0), impression of the amount of medicine (-0.3 ± 1.0 to 0.3 ± 1.0) and number of doses (0.3 ± 1.0 to 0.8 ± 0.6), and medication adherence (0.8 ± 0.4 to 0.9 ± 0.3) as assessed by the questionnaire surveys were significantly improved after switching from DPP-4 inhibitors. The self-reported amount of unused drugs was significantly reduced after switching.
CONCLUSIONS
Switching from daily DPP-4 inhibitors to once-weekly trelagliptin improved the satisfaction with the treatment, impression of the prescribed medicine and medication adherence in the type 2 diabetic patients who expresses a desire to reduce their prescription medicines. In such patients, improvements in the glycemic control and long-term prognosis might be expected through the reduction of unused drugs.
