               cardiovascular outcomes never fully abated, although the data from the CAROLINA trial which compared
               linagliptin with glimepiride and showed no differences in CV outcomes may reassure many with regards to
               sulphonylureas . The role of sulphonylureas in the current landscape perhaps focuses on the management
                            [7]
               of hyperglycaemia, where insulin is not deemed necessary or where quick glucose lowering is required,
                                                                     [8,9]
               including in some instances of steroid-induced hyperglycaemia . From a global perspective, the low cost
               and efficacy in terms of glucose lowering still suggest a role in economies where cost is a key consideration
                                                                                          [10]
               and the role of sulphonylureas in maturity-onset diabetes of the young (MODY) remains .
               Thiazolidinediones, specifically pioglitazone, may not be utilized as often as they once were, in part due to
               alternative options with lesser side effect profiles, but there are still some considerations for their use in type
               2 diabetes. Their effect on those with insulin resistance remains of note, with recent trials such as the
               TriMaster study identifying that in patients with BMI over 30 kg/m , pioglitazone offered greater Hba1c
                                                                          2
