Phylloquinone has been synthesized since at least 1939,[A234384] and was approved by the FDA prior to 1955.[L33389]
[L33345]
Parenteral (intravenous, intramuscular, and subcutaneous) phylloquinone is indicated to treat coagulation disorders due to faulty formation of coagulation factors II, VII, IX, and X caused by vitamin K deficiency or some interference with vitamin K activity.
[L33319]
These indications include the above indications as well as hypoprothrombinemia secondary to sprue, ulcerative colitis, celiac disease, intestinal resection, pancreatic cystic fibrosis, or regional enteritis; or hypoprothrombinemia caused by interference with vitamin k metabolism.
[L33319]
Known interactions with other medications. Always consult a healthcare professional.

[A234259]
Intravenous administration has been associated with an increased risk of toxicity.
[A234284]
These patients should be treated with symptomatic and supportive measures.
The intravenous LD50 in mice is 1170 mg/kg and the oral LD50 is >24180 mg/kg.
[L33345]
Vitamin K may also carboxylate matrix proteins in chondrocytes, inhibiting calcification of joints, and may increase type II collagen.[A234304] The role of vitamin K in osteroarthritis,[A234304] bone density,[A234309] and vascular calcification[A234314] is currently under investigation.
How the body processes this drug — absorption, distribution, metabolism, and elimination
[A234264]
1.5 ± 0.8 nmol is found in the plasma compartment, and 3.6 ± 3.4 nmol is found in the second compartment.
[A234264]
A 10 mg intramuscular phylloquinone dose is 89.2% ± 25.4% bioavailable.
[A234344]
The same dose reaches a mean Cmax of 67 ± 30 ng/mL, with a mean Tmax of 9.2 ± 6.6 hours, and an AUC of 1700 ± 500 h\*ng/mL.
[A234344]
A 10 mg intravenous phylloquinone dose has a mean AUC of 1950 ± 450 h\*ng/mL.

The side chain is then cleaved to 5 or 7 carbons long, and then glucuronidated prior to elimination.
[A234104][A234109][A234114][A234119]
Vitamin Ks in general undergo a cycle of reduction to vitamin K hydroquinone by vitamin K epoxide reductase (VKOR), oxidation to vitamin K epoxide by gamma-glutamyl carboxylase, and converted back to vitamin K by VKOR.
[A234259]
[A234104][A234329]
[A234104][A234329]
A 10 mg intravenous dose of phylloquinone has a mean clearance of 91 ± 24 mL/min.
