Prolyl hydroxylase domain inhibitor for treating hemorrhagic or burn shock

A majority of military casualties occur during the pre-hospital period. The cause of death is largely associated with massive traumatic bleeding that leads to organ damage due to sustained hypoxia. Currently, therapeutics are lacking at the point of injury to mitigate hypoxic damage and maintain the survivability of severe hemorrhage prior to reaching medical facilities. This invention addresses that by introducing a method of co-administering prolyl hydroxylase domain inhibitor (PHDi, MK-8617), anti-fibrinolytic agent (tranexamic acid), and bradykinin receptor antagonist (icatibant) as anti-hemorrhage agents in combination with resuscitation fluid treatment with colloid solution of 25% human albumin that has an advantage of relatively small volume requirement to maintain blood volume. In addition, a kit comprising anti-hemorrhage agents that can be easily carried to the battlefield is also provided here. The therapeutic application of those agents on or near the point of injury can stabilize hypoxia inducible factor-1 alpha and enhance blood clot formation, which improves the patient's cellular adaptation to hypoxia and reduce hemorrhage, and thus can decrease organ failure and increase the patient's survivability.
