Effect of Inhibitors of the Proton Pump on Intestinal Transporters

Effect of Inhibitors of the Proton Pump on Intestinal Transporters and Their Impact on the Pharmacokinetics of Dabigatran - Mechanistic and Clinical Approach -BIPP Study

Dabigatran etexilate is a novel oral anticoagulant. It is indicated in venous thromboembolic prevention in orthopedic surgery and has recently shown greater efficiency and tolerance as anticoagulants in preventing thromboembolism in atrial fibrillation. However, it increases the risk of gastrointestinal bleeding compared to standard treatment (AVK) [3]. In these circumstances the risk / benefit of dabigatran could be improved by combining it with gastric protectors such as inhibitor drugs proton pump (IPP).

Investigators want to evaluate the pharmacokinetic and pharmacodynamic effects of co-administration of these two IPP (omeprazole, rabeprazole) with dabigatran in healthy subjects.
