Sulphonylurea Receptor Mutation and Responsiveness to Gliclazide - a Pilot Proof of Concept, Randomised Cross-over Study

Summary

Gliclazide has greater glucose lowering efficacy than glibenclamide among type 2 diabetes mellitus patients with minor haplotype (K23/A1369) at the KCNJ11/ABCC gene locations.
