The aim of the study was to determine whether administration of rivaroxaban, a factor Xa inhibitor in the coagulation pathway, alleviates the course of cerulein-induced AP and accelerates the pancreatic recovery. In the first part of the study, we administered 5, 20 and 100 mg/kg/dose of rivaroxaban before AP induction with cerulein, in the second part, the drug was administered daily after AP onset. We weighed the pancreas and conducted histopathological examination 6 h after the last dose of cerulein and on days 2, 3, 5, 7 and 10 of the experiment. We measured INR levels, pancreatic enzymes activity, pancreatic blood flow, D-dimer concentration and inflammatory markers such as Interleukin 1β (IL-1β), myeloperoxidase (MPO), superoxide dismutase (SOD) and malondialdehyde (MDA). Rivaroxaban at the dose of 5 and 20 mg/kg reduced the pancreatic damage, such as edema, vacuolization, and the number of hemorrhagic foci. These effects were accompanied by a decrease in the activity of amylase, lipase and the concentration of IL-1β and D-dimers. In addition, an improvement in pancreatic blood flow was observed, and a lower concentration of MDA and a higher SOD in the first days from the AP on}, abstract={set were recorded. Rivaroxaban at 100 mg/kg resulted in increased pancreatic damage and worse AP scores. Early administration of rivaroxaban had a protective effect on the pancreas and treatment with the drug reduced AP severity.}, title={The influence of rivaroxaban on the course and development of experimental acute pancreatitis}, type={Praca doktorska}, keywords={acute pancreatitis, rivaroxaban, coagulation, oxidative stress, cerulein}, }
