Role of glipizide therapy on oxidative stress parameters in the patient with Type-II diabetes mellitus

Background Oxidative stress has an important role in the pathophysiology of diabetes mellitus (DM) Type-II. Oxidative stress has an important role in the progression of DM Type-II and its related complications such as retinopathy, neuropathy and many others. The present study was carried out to evaluate the effect of glipizide therapy on oxidative stress parameters in Type-II DM.

Methods Thirty newly diagnosed diabetes patients were given glipizide therapy on 1st day and continue for 3 months. 30 non-diabetic healthy volunteers served as a control. Plasma malondialdehyde (MDA), superoxide dismutase (SOD) and catalase levels were measured at the time of enrollment and at the end of 3 months of glipizide treatment.

Result Theresults are analyzed using paired t-test. Plasma MDA was significantly increased, whereas SOD and catalase were significantly reduced in newly diagnosed diabetic patients as compared to control. After 3 months of glipizide therapy, plasma MDA was significantly reduced, whereas SOD and catalase were significantly increased.

Conclusion Glipizide therapy significantly reduced oxidative free radicals and increased antioxidant mechanism, which reduced oxidative stress, progression DM-II and its related complication.
