Metaraminol is a potent sympathomimetic amine that increases both systolic and diastolic blood pressure, is an adrenergic receptor alpha-1 agonist.. Metaraminol is indicated for prevention and treatment of the acute hypotensive state occurring with spinal anesthesia. It is also indicated as adjunctive treatment of hypotension due to hemorrhage, reactions to medications, surgical complications, and shock associated with brain damage due to trauma or tumor. Metaraminol is also used in the treatment of priapism, in spite of this application was not approved, it appears to be effective.

Ciraparantag (PER-977, aripazine), developed by Perosphere Inc., is a small, synthetic, water-soluble, cationic molecule and can reverse the anticoagulation mediated by unfractionated heparin, low-molecular-weight heparin, factor Xa and factor IIa inhibitors, and fondaparinux. It has the potential to be a universal antidote, inhibiting nearly all anticoagulants except vitamin K antagonists and argatroban. In April 2015, ciraparantag received FDA fast-track designation as an investigational anticoagulant reversal agent. Phase I/II trials are currently underway to evaluate the safety and efficacy of PER977 in reversing anticoagulation of edoxaban, LMWH, and UFH.2.

Ethamsylate (2,5-dihydroxy-benzene-sulfonate diethylammonium salt) is a synthetic hemostatic drug indicated in cases of capillary bleeding. Ethamsylate acts on the first step of hemostasis by improving platelet adhesiveness and restoring capillary resistance. In addition it inhibits prostaglandin biosynthesis. Well-controlled clinical trials clearly showed the therapeutic efficacy of ethamsylate in dysfunctional uterine bleeding, with the magnitude of blood-loss reduction being directly proportional to the severity of the menorrhagia. Other well-controlled clinical trials showed therapeutic efficacy of ethamsylate in periventricular hemorrhage in very low birth weight babies and surgical or postsurgical capillary bleeding.
