 Use of Patamostat


Patamostat (E-3123) is a potent protease inhibitor. Patamostat potently inhibits trypsin, plasmin and thrombin with IC50s of 39 nM, 950 nM and 1.9 μM, respectively. E-3123 may possess suppressing effects on pathogenesis and development of acute pancreatitis[1][2].

In Vivo Intravenous infusion of Patamostat (E-3123) at 0.03-0.3 mg/kg in rats or at 0.3-3.0 mg/kg in rabbits reduced mortality after the induction of pancreatitis in a dose-dependent manner. In dogs with pancreatitis, increases in serum trypsin and lipase activities were significantly reduced by infusion of Patamostat at 1.0 and 3.0 mg/kg[1]. Patamostat (E3123; continuous infusion in a dose of 2 mg/kg per h) improves almost all parameters, including mortality rate, serum and ascitic fluid amylase levels, plasma endotoxin and serum FDP levels, and distribution of lysosomal enzyme in male Wistar rats[2]. Animal Model: Male Wistar rats weighing about 350 g[2] Dosage: 2 mg/kg Administration: Continuous infusion per h for 1 h Result: Significantly improved the survival rate.
