Pharmacology and Toxicology of Silian Folic Acid Tablets
- Folic acid is a water-soluble B vitamin consisting of pteridine, p-aminobenzoic acid, and glutamic acid residues. It is an essential substance for the growth and reproduction of body cells. Exist in liver, kidney, yeast and green leafy vegetables such as beans, spinach, tomato, carrot, etc., and can now be synthesized artificially. Folic acid forms tetrahydrofolate (THFA) through the action of dihydrofolate reductase and vitamin B12, which combines with a variety of one-carbon units (including CH3, CH2, CHO, etc.) to form tetrahydrofolate coenzymes, delivering one-carbon units It is involved in many important reactions in the body and the synthesis of nucleic acids and amino acids. THFA forms N5,10 methylenyltetrahydrofolate under the action of serine transhydroxylase, which can promote uracil nucleotides (dUMP) to form thymine nucleotides (dTMP), which can be involved in cell DNA synthesis. Promote cell division and maturation. During DNA synthesis, deoxyuridine is converted to deoxythymidylate, during which the required methyl group is provided by methylenetetrahydrofolate. In the absence of folic acid, DNA synthesis is slowed, but RNA synthesis is not affected. As a result, blood cells in the bone marrow have larger volumes and the nucleus develops more naive blood cells, especially red blood cells. Timely supplementation may have a therapeutic effect.
Pharmacokinetics of Silian Folic Acid Tablets
- After oral administration, it is mainly absorbed in the proximal part of the jejunum in a reduced form, appears in the blood within 5-20 minutes, and reaches a peak one hour later, and its t1 / 2 is about 0.7 hours. Anemia patients absorb faster than normal people. Folic acid enters the liver from the portal vein and is stored in the liver in the form of N5-methyltetrahydrofolate and distributed to other tissues and organs. The amount of folic acid stored in the liver is about 1/3 to 1/2 of the total body. About 90% of the therapeutic amount of folic acid is excreted from the urine, and 20% to 30% appear in the urine 2 hours after the high-dose injection.
