Prescribing pattern of anti-diabetic drugs and adherence to the American Diabetes Association's (ADA) 2021 treatment guidelines among patients of type 2 diabetes mellitus: A cross-sectional study

Background: Glycemic control is the major therapeutic objective in diabetes. Poor glycemic control in diabetes mellitus can be prevented by using rational use of anti-diabetic medication, which needs to be evaluated for effectiveness by prescription pattern studies. The objective of this study was to assess the prescribing pattern and adherence to the American Diabetic Association's (ADA) treatment guidelines in type 2 diabetes mellitus patients in a tertiary care teaching hospital in Uttarakhand, India. Methodology: This cross-sectional study was conducted on 206 type 2 diabetic patients who were prescribed anti-diabetic therapy. Patient's demographic details and drugs prescribed, with their dosage, were recorded to study the prescription pattern. Results: Oral anti-diabetic drugs were most commonly prescribed in 149 (72.33%) type 2 diabetic mellitus patients. Five of these patients (3.35%) were on metformin monotherapy, whereas majority of patients (81, 54.36%) were on a fixed dose combination of Glimepiride (SU) + Metformin (MET). Forty-five patients (30.20%) were on MET + Dipeptidyl peptidase 4 inhibitors (DPP4I) combination; 5 (3.35%) were on MET + SU + alpha-glucosidase inhibitors (AGI) combination; 7 (4.69%) were on MET + SU + Pioglitazone (PIO) (Thiazolidinediones) combination; 6 (4.02%) were on sodium/glucose cotransporter-2 inhibitors (SGLT2I) and 57 (27.66%) were on insulin therapy. Out of 206 patients, the prescriptions of 185 patients (89.8%) were adherent and of 21 patients (10.19%) were not adhering to ADA 2021 treatment guidelines. Conclusion: Oral anti-diabetic agents predominate the prescribing pattern practices for type 2 DM but there was a shift in trend towards the use of fixed-dose combinations (FDC) in the management of type 2 DM, and majority of prescriptions were adherent to ADA treatment guidelines.
