https://www.nhs.uk/medicines/alogliptin/ I'm about to trial adding a second medication to the Metformin, for a 3 month period, to see if that improves things. The doctor mentioned Alogliptin. Previously, the nurse suggested Sitagliptin. https://www.januvia.com/sitagliptin/what-is-januvia/ https://www.nhs.uk/medicines/sitagliptin/ Does anyone have any idea which is preferable, and if so why? Both seem to ginger up the pancreas (from the NHS descriptions).
