Effect of combination therapy with repaglinide and metformin hydrochloride on glycemic control in Japanese patients with type 2 diabetes mellitus

Aims/Introduction

We investigated the efficacy and safety of repaglinide as an add‐on therapy for Japanese patients with type 2 diabetes mellitus receiving metformin monotherapy (at a dose of 1,500 mg/day, mainly) in addition to diet and exercise.

Materials and methods

In the 16‐week multicenter, placebo‐controlled, randomized, double‐blind, parallel‐group trial (the phase III study), patients with type 2 diabetes mellitus with metformin monotherapy were randomly assigned to the repaglinide or placebo group. Thereafter, a 36‐week, multicenter, uncontrolled, dose‐titration method study was extended to a total duration of 52 weeks (the long‐term study). The primary end‐point of each study was a change in glycated hemoglobin (HbA_1c) from baseline.

Results

After 16 weeks, mean reductions in HbA_1c were significantly greater for the repaglinide group than for the placebo group (–0.98 ± 0.72% vs 0.13 ± 0.63%, P < 0.001). In the long‐term study, the mean change in HbA_1c was −0.76 ± 0.83%. The rate of adverse events was 60.6 and 50.0% in the repaglinide and placebo groups, respectively, in the phase III study, and 78.3% in the long‐term study. Hypoglycemia was reported in 11.7, 0 and 13.3% of patients in the repaglinide group, placebo group and long‐term study, respectively.

Conclusions

Combination therapy with repaglinide and metformin resulted in an approximately 1% reduction in HbA_1c at week 16 and in a significant long‐term improvement in HbA_1c at the end of the study. No safety problems were noted during the concomitant use of repaglinide and metformin. These studies were registered with JapicCTI (nos. JapicCTI‐101202 and JapicCTI‐101203).     

两种促胰岛素分泌剂对血糖漂移的影响

目的 交叉对比分析瑞格列奈和格列齐特的动态血糖图谱,观察比较血糖波动系数、低血糖发生率和餐后血糖峰值。方法T2DM患者52例,分别应用瑞格列奈或格列齐特,常规检查血糖。采用交叉设计,应用瑞格列奈组患者改用格列齐特,应用格列齐特组患者改用瑞格列奈,改用前后分别予动态血糖监测72h。原有饮食运动及联用口服药物不变。以用瑞格列奈为研究组,用格列齐特为对照组,对比分析两组血糖波动系数、低血糖发生率和餐后血糖峰值。结果经2周洗脱期、8周剂量调整期、2周剂量维持期、3d监测期后的结果显示：应用瑞格列奈比应用格列齐特血糖控制更平稳,动态血糖图谱表现为血糖波动系数小,低血糖次数少,低血糖时间比少（P〈0．01）,餐后血糖峰值低（P＜0．05）。结论本研究条件下,应用瑞格列奈比应用格列齐特似可减少血糖漂移幅度。     

甘精胰岛素联合口服降糖药控制空腹及餐后高血糖的研究

目的探讨甘精胰岛素与口服降糖药联用控制空腹及餐后高血糖的疗效。方法将136例单用口服降糖药血糖控制不理想的T2DM患者随机分为A、B两组。A组采用国产甘精胰岛素（长秀霖）,B组采用进口甘精胰岛素（来得时）,两组在用甘精胰岛素的基础上,均分别与二甲双胍和瑞格列奈联用,观察治疗前后FPG、2hPG及HbA1C水平和低血糖的发生率。结果治疗后两周时FPG、2hPG及HbA1C水平与治疗前相比均明显下降,但仍未达标。两组患者在甘精胰岛素和二甲双胍治疗的基础上加用瑞格列奈,治疗后4周时FPG及2hPG水平均已达标,HbA1C水平于治疗2个月时达标。两组治疗后各项指标与治疗前相比均明显下降（P均〈0．01）,两组临床疗效无统计学差异,低血糖发生率分别为4．2％和4．6％,相比无统计学差异（P〉0．05）。结论两种甘精胰岛素分别与二甲双胍和瑞格列奈联用,能较好控制FPG、2hPG及HbA1C水平,低血糖发生率均较低,临床疗效相近。因此,甘精胰岛素与二甲双胍和瑞格列奈联用是控制FPG、2hPG及HbA1C水平的安全有效的治疗方案。

Oxidative stress in kidney and liver of alloxan-induced diabetic rabbits: effect of repaglinide

Abstract The aim of this study was to analyse the effect of the new oral antidiabetic drug repaglinide on antioxidant factors and lipid peroxidation in tissues of alloxan-induced diabetic rabbits after 4 and 8 weeks treatment. The activity of superoxide dismutase (diabetic vs. control values, mean±S.E.M., p<0.05) in diabetic kidney was diminished (1.5±0.2 vs. 2.8±0.3 and 1.8±0.1 vs. 2.9±0.3 U/mg protein) and significantly increased after 8 weeks of repaglinide treatment (2.4±0.2 U/mg protein). Catalase activity was significantly increased in diabetic liver (67.5±3.6 vs. 39.7±5.6 and 62.3±2.7 vs. 52.6±5.3 µmol H₂O₂/min/mg protein) and normalised by repaglinide (49.2±4.0 and 41.2±3.8 µmol H₂O₂/min/mg protein). In diabetic kidney the level of ascorbic acid was diminished after 4 weeks (1.5±0.1 vs. 3.0±0.1 µmol/g tissue) and increased after the drug treatment (2.0±0.2 µmol/g tissue). In diabetic kidney the level of lipid peroxidation products was elevated (33.3±2.4 vs. 23.7±2.4 and 29.5±3.1 vs. 18.2±0.8 nmol/g tissue) and diminished by repaglinide (10.3±1.4 and 13.3±3.0 nmol/g tissue). This study shows that oxidative stress in diabetic tissues is partly corrected by repaglinide. The drug does not affect glucose concentration and its antioxidative effect is not secondary to its action on hyperglycaemia. This study suggests an additional advantage of repaglinide which contributes to its effectiveness in therapy.     

Effect of repaglinide on cloned beta cell, cardiac and smooth muscle types of ATP-sensitive potassium channels

Aims/hypothesis. The carbamoylbenzoic acid derivative repaglinide is a potent short-acting insulin secretagogue that acts by closing ATP-sensitive potassium (K_ATP) channels in the plasma membrane of the pancreatic beta cell. In this paper we investigated the specificity of repaglinide for three types of cloned (K_ATP) channel composed of the inwardly rectifying potassium channel Kir6.2 and either the sulphonylurea receptor SUR1, SUR2A or SUR2B, corresponding to the beta cell, cardiac and either smooth muscle types of K_ATP channel, respectively. Methods. The action of the drug was studied by whole-cell current recordings of K_ATP channels expressed either in Xenopus oocytes or mammalian cells (HEK293). We also used inside-out macropatches excised from Xenopus oocytes for detailed analysis of repaglinide action. Results. The drug blocked all three types of K_ATP channel with similar potency, by interacting with a low-affinity site on the pore-forming subunit of the channel (Kir6.2: half-maximal inhibition 230 μmol/l) and with a high-affinity site on the regulatory subunit, the sulphonylurea receptor (SUR: half-maximal inhibition 2–8 nmol/l). There was no difference in potency between channels containing SUR1, SUR2A or SUR2B. MgADP potentiated the inhibitory effect of repaglinide on Kir6.2/SUR1 and (to a lesser extent) Kir6.2/SUR2B, but not on Kir6.2/SUR2A. Conclusion/interpretation. Repaglinide interacts with a site common to all three types of sulphonylurea receptor leading to inhibition of the K_ATP channel. The fact that MgADP potentiated this effect in the case of the beta cell, but not cardiac, type of channel could help explain why the drug shows no adverse cardiovascular side-effects in vivo.
