This product is a vitamin medicine. Vitamin K, as a coenzyme of carboxylase, is involved in the synthesis of coagulation factors II, VII, IX, and X. The glutamate residues on these factors must form 9-12 carboxyl valleys under the action of liver microsomal enzyme system carboxylase. Amino acid can make these factors have the ability to bind to Ca2+, and co
nnect the phospholipid surface and regulatory proteins, so that these factors have blood coagulation activity, thereby producing blood coagulation. If vitamin K4 is lacking or the epoxide reduction reaction is blocked (such as antago
nized by coumarins), the synthesis of factors II, VII, IX, and X stays in the precursor state, prolo
nging the prothrombin time and causing bleeding.
Drug interactionsedit
Oral anticoagulants such as dicoumarins can interfere with the metabolism of vitamin K. The two drugs are used at the same time and the effects cancel each other. Salicylic acids, sulfonamides, quinidine, etc. can also affect the effect of vitamin K
