Abstract: Objective: To evaluate the lipid and glycemic effects of Thiazolidinedione group of drugs
(Pioglitazone, Rosiglitazone) in Type 2 diabetic patients with dyslipidemia.Methodogy: After ethical clearance
and informed consent Type 2 diabetic patients with dyslipidemia attending the diabetic out patient clinic of
Diabetology unit of Voluntary health services hospital.Chennai were screened and 45 patients selected for the
study according to WHO criteria for diabetes and National cholesterol Education program guidelines for
dyslipidemia. Each group consisting of 15 patients viz., Group I: Received Glibenclamide 5 mg/day. Group II:
Received Pioglitazone 15 mg/day. Group III: Received Rosiglitazone 4 mg/day. Estimation of serum Total
Cholesterol and HDL Cholesterol,Triglycerides,VLDL, Blood glucose,SGOT,S.GPT levels were estimated.
Anthropometric evaluation and clinical parameters also evaluated. Results and discussion: Pioglitazone group
showed significant reduction (p < 0.05) in fasting and post prandial blood glucose level at 12 week of study
th
when compared with sulphonylurea group. Reduction in total cholesterol level. 16% in pioglitazone, 4% in
rosiglitazone and 1% in sulphonylurea group. Serum Triglycerides showed significant reduction (P< 0.001) in
Rosiglitazone group when compared to sulphonylurea group at 12 week of the study. HDL cholesterol level
th
showed significant increase (p < 0.001) in pioglitazone group when compared to sulphonylurea group in 8
th
week and 12 week of the study. LDL cholesterol level showed significant reduction (p < 0.05) in pioglitazone
th
group when compared to the Rosiglitazone group at 12 week of the study. When compared to pioglitazone,
th
Rosiglitazone showed considerable reduction (p < 0.05) at 4 and 8 week of the study. Liver enzymes study
th th
showed significant increase in SGOT and SGPT levels (p < 0.001) in pioglitazone as well as rosiglitazone group.
Conclusion:Thiazolidinediones group of oral antidiabetic drugs shows hypoglycemic as well as favourable
lipidemic effects on type 2 diabetic patients. Among the two glitazones, pioglitazone showed more favourable
effects of increasing HDL cholesterol. Hence this group of drugs may be considered for use in the early stage
of Type 2 diabetes judiciously to tide over the insulin resistance, hyperglycemia and dyslipidemia and thereby
to prevent cardiovascular morbidity.

INTRODUCTION The prevalence of type 2 diabetes is increasing
Diabetes mellitus is a metabolic disorder of most important and costly disease[2]. India tops the
