Evaluation of Prescribing Pattern, Therapeutic Adherence and Occurrence of Adverse Drug Reactions in Patients with Type 2 Diabetes Mellitus

Abstract

Background: Persistent hyperglycemia in diabetes mellitus (DM) is considered the leading cause of morbidity and mortality associated with both microvascular and macrovascular complications, having a greater economic impact. This study aimed to assess the impact of socioeconomic status, prescribing patterns, and patient compliance in type 2 diabetes mellitus patients. Method: This study was carried out at the Department of Medicine and Diabetic Clinic of Hakeem Abdul Hameed (HAH) Centenary Hospital at Hamdard University, New Delhi, India. We conducted a prospective observational study on prescribing patterns and monitoring adverse drug reactions (ADRs) in patients with type 2 DM (T2DM) under standard care. We enrolled 150 confirmed cases, and data was obtained from pre-validated questionnaires and then coded and analyzed to observe the association between variables. Results: The glycosylated haemoglobin level in 56% of the cases was between 6.4 to 8.0, and cardiovascular complications were observed as the major comorbidities. 45.33 % of the cases were on mono drug therapy, and metformin (23. 52 %) was the drug of choice, followed by glimepiride (23.52 %). Among the dual drug therapies, sitagliptin with metformin and triple-drug therapy, glimepiride concurrent with metformin and voglibose was the most preferred drug in the treatment of T2DM. Sitagliptin was observed to be a major patient burden (46.213 USD). In only 7.33 % of the cases, we observed definite ADR in T2DM patients. Underprivileged awareness, mainly due to low literacy, was a major concern in the development of new cases of T2DM. Conclusion: We observed better patient compliance; however, a disease awareness program must be implemented. The use of oral hypoglycaemic drugs is still dominant in clinical practice and cardiovascular disorders as comorbidities emerge as a greater challenge in terms of patient outcome and cost burden.
