Background: Several new antidiabetic medicines (GLP-1 receptor agonists, DPP-4 inhibitors, and SGLT-2 inhibitors) have been approved by the European Medicines Agency since 2006. The aim of this study was to evaluate the uptake of new antidiabetic medicines in European countries over a 10-year period.
Methods: The study used IQVIA quarterly value and volume sales data January 2006-December 2016. The market uptake of new antidiabetic medicines together with intensity of prescribing policy for all antidiabetic medicines were estimated for Austria, Croatia, France, Germany, Hungary, Italy, Poland, Slovenia, Spain, Sweden, and the United Kingdom. The following measures were determined: number of available new active substances, median time to first continuous use, volume market share, and annual therapy cost.
Results: All countries had at least one new antidiabetic medicine in continuous use and an increase in intensity of prescribing policy for all antidiabetic medicines was observed. A tenfold difference in median time to first continuous use (3-30 months) was found. The annual therapy cost in 2016 of new antidiabetic medicines ranged from EUR 363 to EUR 769. Among new antidiabetic medicines, the market share of DPP-4 inhibitors was the highest. Countries with a higher volume market share of incretin-based medicines (Spain, France, Austria, and Germany) in 2011 had a lower increase in intensity of prescribing policy. This kind of correlation was not found in the case of SGLT-2 inhibitors.
Conclusions: This study found important differences and variability in the uptake of new antidiabetic medicines in the included countries.
