|---|---|
| Main Objective: To assess whether or not there is a difference in biological availibility between vitamin K1 solution in oil or vitamin K1 tablets. ;Secondary Objective: To assess whether or not there is a difference in effectiveness between vitamin K1 solution in oil or vitamin K1 tablets.;Primary end point(s): Step 1: The difference between vitamin K1 levels in blood 4 hours after taking vitamin K1 tablets in comparisson with vitamin K1 solution in oil. The difference in the area under the curve meassured over 24 hours after taking vitamin K1 tablets in comparisson with vitamin K1 solution in oil. Step 2: The difference in the number of INR-values lower than 2.0 when comparing vitamin K1 tablets with vitamin K1 solution in oil after 24 and 48 hours. Step 3: The difference in the decrease of the INR-values 24 hours after taking either vitamin K1 tablets or vitamin K1 solution in oil. The difference in the number of INR-values lower than 2.0 when comparing vitamin K1 tablets with vitamin K1 solution in oil after 24 and 48 hours. The difference in increase of the vitamin K levels in the blood 24 hours after taking either vitamin K1 tablets or vitamin K1 solution in oil. | — |
