Description

Rivaroxaban (Xarelto®) is a direct oral anticoagulant (DOAC) approved by the European Medicine Agency (EMA) in 2008 for the prevention of venous thromboembolism in patients undergoing elec-tive hip or knee replacement surgery in Europe. Due to its anticoagulant properties, bleeding events are the most important serious side effects observed in the registration trials. Since several patient groups show an increased risk of bleeding, specific precautions, warnings, and contraindications apply when using rivaroxaban. In light of this background, EMA demanded further studies from the manufacturer Bayer AG. As a part of the risk management plan, the pharmaceutical company is obliged to investigate the usage and the safety after market approval. The purpose of this drug utilization study was therefore to describe the use of rivaroxaban in Germany.

The focus of this cohort study based on data from the German Pharmacoepidemiological Research Database (GePaRD) , was an analysis of the indication and the duration of use to detect possible off-label use. Furthermore, comorbidity and comedication as defined in the product information were investigated to evaluate the compliance with precautions, warnings, and contraindications during use.

The project was completed in 2012 and the results were published in the European Journal of Clini-cal Pharmacology. Regarding indications, comorbidity, and comedication, most patients receiving rivaroxaban were found to have proper use. In contrast, the recommendations on the duration of rivaroxaban use were not followed by most patients.
