ABSTRACT

Objective To compare the efficacy and safety of compound pioglitazone hydrochloririe glimepiride tablet and glimepiride tablet in the treatment of type 2 diabetic mellitus(T2DM) for evaluating the effectiveness and safety of compound pioglitazone hydrochloride glimepiride tablet for treating T2DM.Methods The random,double-blind,double-dummy,positive drugs parallel control clinical study method was adopted.Thirty-three T2DM patients with poorly controlled blood glucose were randomly assigned to the test group(n=22) and control group(n=11) by the 2 ∶ 1 ratio.The test group was given compound pioglitazone hydrochloride glimepiride tablet,while the control group received glimepiride tablet.The treatment cycle was 12 weeks.The differences of FBG,HbA1c,FINS and HOMA-IR in the two groups were compared between before and after treatment.Moreover the changes of body mass,blood pressure and blood lipids as well as adverse events occurrence were compared between the two groups.Results Thirty-one cases finished the treatment follow up(21 cases in the test group and 10 cases in the control group);the decreased amplitudes of HbA1c levels after 12-week treatment in the test group and control group were (0.99 ± 1.87)％ and (-0.02 ± 0.90) ％ respectively,which of FPG were (0.94 ± 1.87) mmol/L and (0.37 ± 2.62) mmol/L respectively.The FPG and HbA1c levels after treatment in the test group were decreased compared with before treatment,the difference was statistically significant (P＜0.01).The change difference of FPG and HbA1c in the control group had no statistical difference(P＞0.05).FINS and HOMO-IR in the test group were significantly decreased before and after treatment,the difference was statistically significant (P＜0.01).The incidence rate of hypoglycemia had no statistically significant difference between the test group and control group.Conclusion The effectiveness of compound pioglitazone hydrochloride glimepiride tablet in treating T2 DM is superior to the single use of glimepiride,while the safety is equivalent to single use of glimepiride.
