Introduction: Basal insulin is among the second line treatment options for Type 2 Diabetes Mellitus (T2DM). Efficacy and safety of basal insulin in patients of T2DM, uncontrolled with Oral Antidiabetic Agents (OAAs) remains understudied in the Indian setting.

Aim: To assess the efficacy and safety of insulin glargine in patients with T2DM who have uncontrolled glycaemic levels despite single or two OAAs therapy.

Materials and Methods: In this prospective, open label study, T2DM patients above 40 years of age, having inadequate glycaemic control [Glycosylated Haemoglobin (HbA1c) above 8% and/or fasting glucose level of 140 mg/dl and above] with single or two OAAs over three consecutive months were included. Dosing of insulin glargine was adjusted as per Fasting Blood Glucose (FBG) and Post Prandial Blood Glucose (PPBG) levels. Patients were followed for 12 weeks and data was analysed by comparing 12th week findings to baseline values.

Results: In 40 cases included in final analysis, mean age was 56.35 6.77 years, 52.5% were females and mean body mass index was 26.96 4.59 kg/m2 . Compared to baseline, significant reduction in HbA1c, FBG and PPBG blood glucose (all p<0.05) was seen. HbA1c goal of < 7% was achieved in 37.5% cases. Systolic (p>0.05) and diastolic (p<0.05) blood pressures reduced at 12 weeks as compared to baseline. Increase in weight was modest with mean increase of 1.06 kg (p>0.05). Overall, 14 symptomatic hypoglycaemia events were observed with none being severe.

Conclusion: Short term administration of insulin glargine is effective in reducing glycaemia and is safe with lower rates of severe hypoglycaemia. It can be considered in patients with uncontrolled T2DM on mono- or two- OAAs treatment.
