Sulfonylurea prescription patterns in elderly patients with type 2 diabetes mellitus: A comprehensive analysis of real‐world data from pharmacies in Japan.

Aims/Introduction: The study aim was to investigate sulfonylurea prescription patterns in elderly patients (age ≥65 years) with type 2 diabetes mellitus in Japan. Sulfonylurea use among older adults has been insufficiently examined, despite the associated risks of hypoglycemia. Materials and Methods: This retrospective cross‐sectional survey entailed analysis of Japanese pharmacy data, extracted from the Musubi database, for patients (age 20–100 years) prescribed sulfonylureas between November 2022 and October 2023. Dose distribution, adherence to the Diabetes Treatment Guidelines for the Elderly 2023 and coprescription of other diabetes medications were investigated. Results: Of the total 91,229 patients, 80.1% were prescribed glimepiride, 16.3% gliclazide and 3.6% glibenclamide. In patients aged ≥65 years, exceeding the recommended dose (>1 mg/day for glimepiride, >40 mg/day for gliclazide) was numerically higher for glimepiride (25.0%) than for gliclazide (7.8%). The most common prescribing patterns were quadruple therapy with a sulfonylurea, a dipeptidyl peptidase‐4 inhibitor, an sodium–glucose transporter 2 inhibitor and a biguanide in patients aged 65 to <75 years, and dual therapy with a sulfonylurea and a dipeptidyl peptidase‐4 inhibitor in patients aged ≥75 years. Unfortunately, glinide was coprescribed for 338 (0.5%) of elderly patients. Insulin was coprescribed for 3,682 (5.6%) of elderly patients. Conclusions: Analysis of real‐world sulfonylurea prescription data found guideline non‐adherence, namely, excessive prescription of glimepiride, use of glibenclamide in elderly patients, and common coprescription with dipeptidyl peptidase‐4 inhibitors. These findings might provide an opportunity to reconsider the treatment of patients with type 2 diabetes mellitus who are over‐prescribed sulfonylureas to reduce residual risks, such as hypoglycemia.
