N2 - Introduction: Ibuprofen is commonly used by warfighters in the deployed environment. This study investigated its dose effects on in vitro coagulation in human and pig blood. Methods: Blood samples were collected from 6 normal volunteers and 6 healthy pigs and processed to make platelet-adjusted samples (100 × 103/μL, common transfusion trigger in trauma). Ibuprofen was added to the samples at concentrations of 0 μg/mL (control), the concentration from the highest recommended oral dose (163 μg/mL, 1×), and 2×, 4×, 8×, 10×, 12×, 16×, and 20×. Platelet aggregation by Chrono-Log aggregometer and coagulation by rotational thrombelastogram (Rotem) were assessed at 15 minutes after the addition of ibuprofen. Results: A robust inhibition of ibuprofen on arachidonic acid-induced platelet aggregation was observed at all doses tested in human or pig blood. Collagen-stimulated platelet aggregation was inhibited starting at 1× in human blood and 4× in pig blood. Rotem measurements were similarly compromised in pig and human blood starting at 16×, except clot formation time was prolonged at 1× in human blood (all p < 0.05). Conclusion: Ibuprofen inhibited platelet aggregation at recommended doses, and compromised coagulation at higher doses. Human blood was more sensitive to ibuprofen inhibition. Further effort is needed to investigate ibuprofen dose responses on coagulation in vivo.
