Noxifol-D – Clinical Pharmacology

The in vivo synthesis of the major biologically active metabolites of vitamin D occurs in two steps. The first hydroxylation of Vitamin D takes place in the liver (to 25-hydroxyvitamin D) and the second in the kidneys (to 1,25-dihydroxyvitamin D). Vitamin D metabolites promote the active absorption of calcium and phosphorus by the small intestine, thus elevating serum calcium and phosphate levels sufficiently to permit bone mineralization. Vitamin D metabolites also mobilize calcium and phosphate from bone and probably increase the reabsorption of calcium and perhaps also of phosphate by the renal tubules.

There is a time lag of 10 to 24 hours between the administration of vitamin D and the initiation of its action in the body due to the necessity of synthesis of the active metabolites in the liver and kidneys. Parathyroid hormone is responsible for the regulation of this metabolism in the kidneys.

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 defective deoxyribonucleic acid (DNA) synthesis that leads to megaloblast formation and megaloblastic and macrocytic anemias.

Folic acid is absorbed rapidly from the small intestine, primarily from the proximal portion. Naturally occurring conjugated folates are reduced enzymatically to folic acid in the gastrointestinal tract prior to absorption. Folic acid appears in the plasma approximately 15 to 30 minutes after an oral dose; peak levels are generally reached within 1 hour.


This product is contraindicated in patients with a known hypersensitivity to any of the ingredients. Noxifol-D is contraindicated in patients with hypercalcemia, malabsorption syndrome, abnormal sensitivity to the toxic effects of vitamin D, and hypervitaminosis D.

Warnings and Precautions

KEEP OUT OF THE REACH OF CHILDREN. In case of an accidental overdose, call a doctor or a poison control center immediately.

Tell your doctor if you have: kidney problems or thyroid disease.

This medication should be used as directed by your physician during pregnancy or while breast-feeding. Consult your doctor about the risks and benefits.

Folic acid alone is improper therapy in the treatment of pernicious anemia and other megaloblastic anemias where vitamin B12 is deficient. Folic acid in doses above 0.1 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurological manifestations progress.

There is evidence that the anticonvulsant action of phenytoin is antagonized by folic acid. A patient whose epilepsy is completely controlled by phenytoin may require increased doses to prevent convulsions if folic acid is given.

Adverse Reactions

Allergic sensitization has been reported following both oral and parenteral administration of folic acid.

Call your doctor if you experience any of the following rare but possible signs of hypervitaminosis D: nausea, vomiting, constipation, loss of appetite, increased thirst, increased urination, mental/mood changes or unusual tiredness.

You should call your doctor for medical advice about serious adverse events. To report adverse side effects or to obtain product information, contact Solutech Pharmaceuticals LLC, at 1-877-829-3135
