Pharmacodynamic properties: FOLVIN (Folic acid) is a component of the B group of vitamins and is necessary for the normal production and maturation of red blood cells. It is essential in the synthesis and maintenance of nucleoprotein in erythropoesis. FOLVIN is needed to carry one-carbon groups for methylation reactions and nucleic acid synthesis. It also promotes WBC and platelet production in folate-deficiency anaemia. FOLVIN is also necessary for the production and maintenance of new cells, for DNA synthesis and RNA synthesis. It is especially important during periods of frequent cell division and growth, such as infancy and pregnancy.
Absorption: Rapidly absorbed mainly from the duodenum and jejunum; Time to peak plasma concentrations: 0.5-1 hr.
Distribution: Extensively bound to plasma protein. Principal site of storage is the liver. It is also concentrated in the CSF and enters the breast milk.
Metabolism: Undergoes conversion in the plasma and liver to the metabolically active 5-methyltetrahydrofolate.
Excretion: Via urine (as unchanged drug and metabolites).
