Investigators at INSERM zero in on abdominal aortic aneurysm.(Report)

According to a study from Paris, France, "Platelet activation and thrombus renewal are keys to intraluminal thrombus formation and progression of abdominal aortic aneurysms (AAA). This study explored the ability of AZD6140, a P2Y(12) receptor antagonist, to inhibit platelet activation and prevent aneurysm development in a rat experimental model of AAA."

"Aortic aneurysms were induced by implanting a segment of sodium dodecyl sulfate-decellularized guinea pig aorta in rat aortas. One day later, rats were randomized to AZD6140 (10 mg/kg twice daily by mouth) or diluent (n = 23 per group) for either 10 (n = 18) or 42 days (n = 28). Adenosine diphosphate (ADP)-mediated …
