Objectives: Prevalence of metabolic syndrome (MS) is ~25% and it is currently becoming prevalent in children also. India is estimated to have the maximum number of patients of MS in the world. As insulin resistance is an integral part of MS and the rate of secondary sulfonylurea failure (SSUF) is also high, the present study was planned to evaluate the effects of insulin sensitizers as add-on therapy in MS with SSUF. Materials and Methods: An open-label, prospective, randomized study was conducted on 200 patients of MS with SSUF, included according to ATP III criteria, after dividing them into two groups. Group I patients were given pioglitazone 30 mg/day while group II patients were given metformin 1,000 mg/day as add-on therapy to the sulfonylurea already prescribed. Results: Fall in fasting blood glucose, glycosylated hemoglobin and serum triglycerides was higher with metformin, but rise in high-density lipoprotein-cholesterol was higher with pioglitazone. Only metformin caused a significant reduction in body mass index. Significant reduction in waist circumference, systolic blood pressure and diastolic blood pressure was not seen with any therapy. Incremental cost-effective ratio was almost six-times higher with pioglitazone. Conclusion: Among insulin sensitizers, metformin has more favorable, persistent and multifacet effects in MS with SSUF. Studies of longer duration are required for calculating reduction in the mortality and morbidity.
