DESCRIPTION
Folic acid, USP, N-[p-[[(2-amino-4- hydroxy-6-pteridinyl) methyl]-
amino] benzoyl]-
Lglutamic acid, is a B complex vitamin containing a pteridine moiety
linked by a
methylene bridge to _para_-aminobenzoic acid, which is joined by a
peptide linkage to
glutamic acid. Conjugates of folic acid, USP are present in a wide
variety of foods,
particularly liver, kidneys, yeast, and leafy green vegetables.
Commercially available folic
acid, USP is prepared synthetically. Folic acid, USP occurs as a
yellow or yellowish-
orange crystalline powder and is very slightly soluble in water and
insoluble in alcohol.
Folic acid, USP is readily soluble in dilute solutions of alkali
hydroxides and carbonates,
and solutions of the drug may be prepared with the aid of sodium
hydroxide or sodium
carbonate, thereby forming the soluble sodium salt of folic acid, USP
(sodium folate).
Aqueous solutions of folic acid, USP are heat sensitive and rapidly
decompose in the
presence of light and/or riboflavin; solutions should be stored in a
cool place protected
from light.
The structural formula of folic acid, USP is as follows:

Each tablet, for oral administration, contains 1 mg folic acid, USP.
Folic acid tablets, USP 1 mg contain the following inactive
ingredients: lactose
monohydrate, microcrystalline cellulose, sodium starch glycolate and
stearic acid.
CLINICAL PHARMACOLOGY
Folic acid acts on megaloblastic bone marrow to produce a normoblastic
marrow.
In man, an exogenous source of folate is required for nucleoprotein
synthesis and the
maintenance of normal erythropoiesis. Folic acid is the precursor of
tetrahydrofolic acid,
which is involved as a cofactor for transformylation reactions in the
biosynthesis of
purines and thymidylates of nucleic acids. Impairment of thymidylate
synthesis in
patients with folic acid deficiency is thought to account for the
