This life threatening disease is associated with worsening of glycemic control and progressive metabolic dysfunctions. Objective: Current study aimed to investigate the effect of hydroxychloroquine (HCQ) as an adjunct to glibenclamide or metformin on glycemic control in alloxan induced diabetic rats. Methods: HCQ was combined separately with two conventional anti-diabetic drugs;glibenclamide and metformin. At first, alloxan (120 mg/kg) induced diabetic rats were treated with single dose of metformin (850 mg/70 kg BW), glibenclamide (10 mg/70 kg BW) and HCQ (300 mg/70 kg BW) intraperitoneally once daily for two weeks. Then non fixed dose combinations of glibenclamide (5 mg/70 kg BW) with HCQ (150 mg/70 kg BW) and metformin (425 mg/70 kg BW) with HCQ (150 mg/70 kg BW) were injected along with those of the three drugs alone once daily for four weeks. Results: In alloxan induced diabetic rats, glibenclamide, metformin and their combination therapies reduced blood glucose level significantly but combination therapies are the most effective. Glibenclamide or metformin in combination with HCQ also significantly (P < 0.05) reduced the elevated levels of total cholesterol, triglycerides, and low density lipoprotein cholesterol (LDL-C) level and increased high density lipoprotein cholesterol (HDL-C) level. Moreover, HCQ potentiates the liver glycogen synthesis of metformin or glibenclamide. Conclusion: Outcomes of this investigation indicate that combination of glibenclamide or metformin with HCQ improves glycemic control and provides additional metabolic benefits, not achieved with either glibenclamide or metformin alone.展开更多

Primarily acute toxicity study and oral glucose tolerance test were performed. Diabetes was confirmed after 12 days of single intraperitoneal injection of alloxan (120 mg/kg BW) in albino male rats. Rats were divided into six groups’;normal control (Group I) and diabetic induced groups as (Group II, III, IV, V and VI). Group III & IV were treated with leaf extract of S. japonica (200 mg/kg BW & 350 mg/kg BW). Group V (Met 850 mg/70 kg BW) and group VI: (combination of Met 425 mg/70 kg BW and LE 250 mg/kg BW) for four weeks. Body weight of each rat in the different groups was recorded at 0, 7th, 14th, 21st and 28th day of treatment. TC, TG, LDL-C and HDL-C were measured analytically after 28 days of treatment. Alloxan induction also caused left ventricular hypertrophy. LE of S. Japonica showed a good result in OGTT. Oral treatment of different doses of LE and combination therapy reduced elevated level of BG, TC, TG, LDL-C and increased HDL-C level significantly (p S. japonica (Thunb.) Miers showed antihyperlipidemic and antidiabetic effect and hence could be suggested as a potential therapeutic agent for diabetic treatment.展开更多
