- Medications that may interfere with the study such as alpha-glucosidase inhibitors (e.g. acarbose), insulin-sensitising drugs (e.g. metformin, thiazolidinediones), sulfonylureas, and lipid-lowering drugs. Other medications, should be reviewed by medical representative from KCL on a case by case basis.
