Nafamostat mesylate (INN), a synthetic serine protease inhibitor, it is a short-acting anticoagulant,[1] and is also used for the treatment of pancreatitis. It also has some potential antiviral and anti-cancer properties.[2] Nafamostat is a fast-acting proteolytic inhibitor and used during hemodialysis to prevent the proteolysis of fibrinogen into fibrin.[3] The mechanism of action of Nafamostat is as a slow tight-binding substrate, trapping the target protein in the acyl-enzyme intermediate form, resulting in apparent observed inhibition. [4][5]

It inhibits a large number of Lys/Arg specific serine proteinases, and is also a tryptase inhibitor, which is implicated in leaking blood vessels which is symptomatic of dengue hemorrhagic fever and of end-stage dengue shock syndrome. It is available in a generic form already used for the treatment of certain bleeding complications in some countries, there are risks of severe complications such as: agranulocytosis, hyperkalemia, and anaphylaxis which must be weighed in non-emergency care.[6] In some countries, it used as a treatment for pancreatitis and pancreatic cancer.[citation needed]

This drug has been identified as a potential therapy for COVID-19,[7] with clinical trials in Japan possibly set to begin in March 2020.[8] With evidence that Nafamostat is a potent anti-viral inhibitor in lung cells, a second round of clinical trials in Korea has begun with 10 hospitals participating.[9]

Multiple Phase 2/3[10][11][12] and Phase 3[13][14] clinical trials for COVID-19 in different countries are ongoing.
