Abstract
Background: Diabetes Mellitus (DM) has been a global epidemic in the new millennium and the majority of all diabetic patients constitute Type 2 diabetes mellitus. Medication adherence to prescribed treatments is a key determinant to achieve therapeutic success reduces diabetic complications.
 Objectives: The aim of the study was to examine the level of medication adherence to Type 2 diabetic patients hospitalized at tertiary care hospital in Bangladesh.
 Methods: The study was descriptive cross-sectional design. A total of 112 Type 2 diabetic patients were conveniently recruited from tertiary care hospital in Bangladesh.
 Results: The mean age of the participants was 57.46 (SD=11.65) years. More than half of the patients (60.7%) were male and majority of them (94.6%) were married. The mean score of diabetic medication adherence was calculated as 26.46 (SD=1.58). Adherence to diabetic medications was significantly associated with age (p=.01), occupation (p=.003), duration of DM (p=.003), oral hypoglycemic agents (p=.02), HbA1c (p=< .01) and Fasting Blood Ssugar (p=< .01). Medication non-adherence significantly found in patients with presence of diabetic retinopathy (p=<.01), microabuminuria (p=.01), dyslipidemia (p=.006), hypertension (p=.01) and other chronic diseases (p=.01).
 Conclusion: The level of medication adherence among Type 2 diabetic patients was found to be suboptimal. Good adherence has beneficial effects on HbA1c and FBS. For improving adherence particular focus should pay to diabetic patients with different age groups and the presence of comorbidities.

Diabetes mellitus (DM) has been a global epidemic in the new millennium and the majority of all diabetic patients constitute Type 2 DM
Diabetes mellitus (DM) most commonly fast-growing non-communicable disease is a global epidemic in the new millennium [1] and considered as the largest global health emergencies [2]
Most patients in this study were found to be medication adherents, but nonadherence to diabetic medication was significantly seen in patients with different age groups, occupations, and the presence of comorbidities
Summary
Diabetes mellitus (DM) has been a global epidemic in the new millennium and the majority of all diabetic patients constitute Type 2 DM. The aim of the study was to examine the level of medication adherence to Type 2 diabetic patients hospitalized at tertiary care hospitals in Bangladesh. Type 2 DM accounts for 90-95% of all diabetes around the world [2,5] is identified as a major health problem in Bangladesh. The prevalence of Type 2 diabetes has an increasing trend in both urban and rural areas in Bangladesh ranged between 4.5% and 3.5% [6],respectively, and those who had higher family income had significantly higher prevalence than those with lower income [7]. Logical applications of antidiabetic treatment and congruous adherent to prescribed medications are the main factors to attain medicinal success [9]
