Qigris Uses, Dosage, Side Effects and more

Qigris 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. Qigris was withdrawn from the market after a major study indicated that it was not effective in improving outcomes in patients with sepsis.

Uses

Qigris is a form of recombinant activated human protein C used to reduce mortality in patients with severe sepsis by inhibiting coagulation Factors V and VIII.

For reduction of mortality in patients with severe sepsis.

How Qigris works

Activated protein C combines with protein S on platelet surfaces and then degrades factor Va and factor VIIIa, thereby reducing blood coagulability.

Food Interaction

Avoid herbs and supplements with anticoagulant/antiplatelet activity. Examples include garlic, ginger, bilberry, danshen, piracetam, and ginkgo biloba.
