ingredient information
Phtonadione Vitamin K1
Vitamin K is essential for the hepatic synthesis of factors II, VII, IX, and X, all of which are essential for blood clotting. Vitamin K deficiency causes an increase in bleeding tendency, demonstrated by ecchymoses, epistaxis, hematuria, GI bleeding, and postoperative and intracranial hemorrhage. Phytonadione is similar to natural vitamin K. GI absorption occurs only via intestinal lymphatics and requires the presence of bile salts. Vitamin K is not effective in reversing the anticoagulant effect of heparin.
