Diabetes prevention: Meta-analysis finds glitazones superior to other oral antidiabetic drug classes
A systematic review assessing the comparative effectiveness of oral anti-diabetic drugs for preventing patients at high risk from progressing to type 2 diabetes has found glitazones (pioglitazone, rosiglitazone), biguanides (metformin), and alpha-glucosidase inhibitors (AGIs; acarbose, voglibose) reduced the relative risk of diabetes by as much as 63%, whereas insulin secretagogues (sulfonylureas and glinides) had no effect.
