Abstract

This prospective, 16-week, randomised, double-blind, parallel-group study assessed the differential impact of the prandial glucose regulating oral hypoglycaemic drug, repaglinide, and placebo upon perceptions of quality of life (QoL) and treatment satisfaction in pharmacotherapy-naive patients with Type 2 diabetes. In addition, the study assessed whether these outcomes were influenced by the patients' level of glycaemic control. A total of 253 patients were randomised in a 2:1 ratio of repaglinide: placebo, with doses taken flexibly with main meals (2-4 per day), whenever they were eaten. Repaglinide was initiated at 0.5 mg per meal, increased to 1 mg after 4 weeks if fasting plasma glucose exceeded 7.8 mmol/l. QoL and treatment satisfaction outcomes were compared using generic and disease-specific self-assessment measures, previously applied in diabetes: the WHO Wellbeing Questionnaire (WHO-WBQ), WHO Diabetes Treatment Satisfaction Questionnaire (WHO-DTSQ) and EuroQoL EQ-5D. Over the trial period, repaglinide-treated patients reported a significant 9% improvement in (WHO-DTSQ) treatment satisfaction score (p < 0.05). No significant increase was associated with placebo. The correlation between decrease in glycated haemoglobin (HbA1c) and increase in treatment satisfaction (WHO-DTSQ) was -0.22 (p < 0.01). Scores obtained with the other measures did not change significantly during the trial in either group, but the cohort exhibited only a slight reduction in wellbeing (WHO-WBQ) and health status (EQ-5D) at baseline compared with the background population. In conclusion, flexible mealtime dosing with oral medication appears to be well accepted by pharmacotherapy-naïve patients with Type 2 diabetes. The results suggest that repaglinide provides a higher level of treatment satisfaction than placebo, and this may in part relate to improved glycaemic control.
