Refill adherence of antihyperglycaemic drugs related to glucose control (HbA1c) in patients with type 2 diabetes.

The aim of this study was to examine a potential association between: (1) refill adherence to antihyperglycaemic drugs and glucose control, and (2) adherence to antihyperglycaemic and cardiovascular drugs for the same patients. Consecutive patients with type 2 diabetes at six Swedish health centres were included. Refill adherence was determined from repeat prescriptions.
