| Description | Drotrecogin alfa is activated human protein C that is synthesized by recombinant DNA technology. It is a glycoprotein of approximately 55 kilodalton molecular weight, consisting of a heavy chain and a light chain linked by a disulfide bond. Drotrecogin alfa was withdrawn from the market after a major study indicated that it was not effective in improving outcomes in patients with sepsis. |
| Indication/Disease | For reduction of mortality in patients with severe sepsis. |
| Pharmacodynamics | Drotrecogin alfa is activated human protein C that is synthesized by recombinant DNA technology. It is a glycoprotein of approximately 55 kilodalton molecular weight, consisting of a heavy chain and a light chain linked by a disulfide bond. Drotrecogin alfa inhibits factor Va and VIIIa, thereby reducing the coagulability of blood. |
| Mechanism of Action | Activated protein C combines with protein S on platelet surfaces and then degrades factor Va and factor VIIIa, thereby reducing blood coagulability. |
