Pyridoxine (vitamin B6) is used to prevent or treat low levels of vitamin B6 in people who do not get enough of the vitamin from their diets. Most people who eat a normal diet do not need extra vitamin B6. However, some conditions (such as alcoholism, liver disease, overactive thyroid, heart failure) or medications (such as isoniazid, cycloserine, hydralazine, penicillamine) can cause low levels of vitamin B6. Vitamin B6 plays an important role in the body. It is needed to maintain the health of nerves, skin, and red blood cells.

Pyridoxine has been used to prevent or treat a certain nerve disorder (peripheral neuropathy) caused by certain medications (such as isoniazid). It has also been used to treat certain hereditary disorders (such as xanthurenic aciduria, hyperoxaluria, homocystinuria).

How Awardin Plus works

Calcium glycerophosphate in combination with sodium monofluorophosphate was found to reduce the acid solubility of enamel. This is thought to be due to increased uptake of fluoride in a non-alkali soluble form at the expense of a fraction remaining in the alkali-soluble form of calcium fluoride . It is also thought that calcium glycerophosphate enhances the remineralization effect of sodium monofluorophosphate leading to greater remineralization of enamel but the mechanism behind this is unknown.

Calcium glycerophosphate reduces the decrease in plaque pH produced by sucrose solutions . This may be due to the buffering action of donated phosphate which acts as an acceptor to three hydrogen ions to form biphosphate, dihydrogen phosphate, and finally phosphoric acid. As bisphosphate and dihydrogen phosphate are amphoteric, these molecules can act as buffers against both acids and bases.

Studies on plaque-modification by calcium glycerophosphate have been inconsistent . Redections in plaque weight and plaque area have been noted in separate studies but neither has been confirmed and no causative link has been established in regards to calcium glycerophosphate's anti-caries effect.

Calcium glycerophosphate donates Calcium and inorganic phosphate resulting in elevated levels of the ions in plaque . These ions are important components of the mineral structure of teeth. As such, their presence supports maintenance of healthy tooth structure and mineralization.

In electrolyte replacement calcium glycerophosphate again acts as a donor of Calcium and phosphate. See Calcium Phosphate for pharmacological descriptions of calcium and phosphate.

Vitamin B12 serves as a cofactor for methionine synthase and L-methylmalonyl-CoA mutase enzymes. Methionine synthase is essential for the synthesis of purines and pyrimidines that form DNA. L-methylmalonyl-CoA mutase converts L-methylmalonyl-CoA to succinyl-CoA in the degradation of propionate , an important reaction required for both fat and protein metabolism. It is a lack of vitamin B12 cofactor in the above reaction and the resulting accumulation of methylmalonyl CoA that is believed to be responsible for the neurological manifestations of B12 deficiency . Succinyl-CoA is also necessary for the synthesis of hemoglobin .

In tissues, vitamin B12 is required for the synthesis of methionine from homocysteine. Methionine is required for the formation of S-adenosylmethionine, a methyl donor for nearly 100 substrates, comprised of DNA, RNA, hormones, proteins, as well as lipids . Without vitamin B12, tetrahydrofolate cannot be regenerated from 5-methyltetrahydrofolate, and this can lead to functional folate deficiency , . This reaction is dependent on methylcobalamin (vitamin B12) as a co-factor and is also dependent on folate, in which the methyl group of methyltetrahydrofolate is transferred to homocysteine to form methionine and tetrahydrofolate. Vitamin B12 incorporates into circulating folic acid into growing red blood cells; retaining the folate in these cells . A deficiency of vitamin B12 and the interruption of this reaction leads to the development of megaloblastic anemia.

Iron is necessary for the production of hemoglobin. Iron-deficiency can lead to decreased production of hemoglobin and a microcytic, hypochromic anemia.

Folic acid, as it is biochemically inactive, is converted to tetrahydrofolic acid and methyltetrahydrofolate by dihydrofolate reductase (DHFR). These folic acid congeners are transported across cells by receptor-mediated endocytosis where they are needed to maintain normal erythropoiesis, synthesize purine and thymidylate nucleic acids, interconvert amino acids, methylate tRNA, and generate and use formate. Using vitamin B12 as a cofactor, folic acid can normalize high homocysteine levels by remethylation of homocysteine to methionine via methionine synthetase.

Vitamin B6 is the collective term for a group of three related compounds, pyridoxine (PN), pyridoxal (PL) and pyridoxamine (PM), and their phosphorylated derivatives, pyridoxine 5'-phosphate (PNP), pyridoxal 5'-phosphate (PLP) and pyridoxamine 5'-phosphate (PMP). Although all six of these compounds should technically be referred to as vitamin B6, the term vitamin B6 is commonly used interchangeably with just one of them, pyridoxine. Vitamin B6, principally in its biologically active coenzyme form pyridoxal 5'-phosphate, is involved in a wide range of biochemical reactions, including the metabolism of amino acids and glycogen, the synthesis of nucleic acids, hemogloblin, sphingomyelin and other sphingolipids, and the synthesis of the neurotransmitters serotonin, dopamine, norepinephrine and gamma-aminobutyric acid (GABA).

Ubidecarenone is an essential cofactor in the mitochondrial electron transport chain. Its functions are the acceptance of electrons from the complex I and II and this activity is vital for the production of ATP. It acts as a mobile redox agent shuttling electrons and protons in the electron transport chain. Ubidecarenone also presents antioxidant activity in mitochondria and cellular membranes, protecting against peroxidation of lipid membranes as well as inhibiting oxidation of LDL-cholesterol.

Coenzyme Q10 is well tolerated and having no significant side effects. Mild gastrointestinal symptoms such as nausea, diarrhea and epigastric distress have been reported.

Toxicity

LD50 Oral (mouse): > 5,000 mg/kg .

General toxicity

Vitamin B12 is generally non-toxic, even at higher doses. Mild, transient diarrhea, polycythemia vera, peripheral vascular thrombosis, itching, transitory exanthema, a feeling of swelling of entire body, pulmonary edema and congestive heart failure in early treatment stages, anaphylactic shock and death have been observed after vitamin B12 administration .

Carcinogenesis and mutagenesis

Long term studies in animals examining the carcinogenic potential of any of the vitamin B12 formulations have not completed to date. There is no evidence from long-term use in patients with pernicious anemia that vitamin B12 has carcinogenic potential. Pernicious anemia is known to be associated with an increased incidence of stomach carcinoma, however, this malignancy has been attributed to the underlying cause of pernicious anemia and has not been found to be related to treatment with vitamin B12 .

Use in pregnancy

No adverse effects have been reported with ingestion of normal daily requirements during pregnancy .

A note on the use of the nasal spray in pregnancy

Although vitamin B12 is an essential vitamin and requirements are increased during pregnancy, it is currently unknown whether the nasal spray form can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. The nasal spray form should be given to a pregnant woman only if clearly needed, as it is considered a pregnancy category C drug in this form. Sufficient well-controlled studies have not been done to this date in pregnant women .

Use in lactation

Vitamin B12 has been found distributed into the milk of nursing women in concentrations similar to the maternal blood vitamin B12 concentrations. No adverse effects have been reported to date with intake of normal required doses during lactation .

Acute iron overdosage can be divided into four stages. In the first stage, which occurs up to six hours after ingestion, the principal symptoms are vomiting and diarrhea. Other symptoms include hypotension, tachycardia and CNS depression ranging from lethargy to coma. The second phase may occur at 6-24 hours after ingestion and is characterized by a temporary remission. In the third phase, gastrointestinal symptoms recur accompanied by shock, metabolic acidosis, coma, hepatic necrosis and jaundice, hypoglycemia, renal failure and pulmonary edema. The fourth phase may occur several weeks after ingestion and is characterized by gastrointestinal obstruction and liver damage. In a young child, 75 milligrams per kilogram is considered extremely dangerous. A dose of 30 milligrams per kilogram can lead to symptoms of toxicity. Estimates of a lethal dosage range from 180 milligrams per kilogram and upwards. A peak serum iron concentration of five micrograms or more per ml is associated with moderate to severe poisoning in many.

IPR-MUS LD₅₀ 85 mg/kg,IVN-GPG LD₅₀ 120 mg/kg, IVN-MUS LD₅₀ 239 mg/kg, IVN-RAT LD₅₀ 500 mg/kg, IVN-RBT LD₅₀ 410 mg/kg

Oral Rat LD50 = 4 gm/kg. Toxic effects include convulsions, dyspnea, hypermotility, diarrhea, ataxia and muscle weakness.

There have not been reports of adverse events of diet supplementation with ubidecarenone. The normal side effects reported in humans are related to the gastrointestinal tract.

Antidiabetic medications: Coenzyme Q10 may improve glycemic control in some type II diabetics. If this were to occur, antidiabetic medications might need appropriate adjusting

Volume of Distribution

Cobalamin is distributed to tissues and stored mainly in the liver and bone marrow .

Tetrahydrofolic acid derivatives are distributed to all body tissues but are stored primarily in the liver.

Pyridoxine main active metabolite, pyridoxal 5’-phosphate, is released into the circulation (accounting for at least 60% of circulating vitamin B6) and is highly protein bound, primarily to albumin.

Ubidecarenone is distributed to the various tissues of the body and it is able to enter the brain. In preclinical studies with intravenous administration of ubidecarenone, it is reported a volume of distribution of 20.4 L/kg which reflects its ability to penetrate extensively into organs and tissues. AS a general rule, tissues with high-energy requirements or metabolic activity tend to presents higher amounts of ubidecarenone, these organs can be heart, kidney, liver and muscle.

Elimination Route

Vitamin B12 is quickly absorbed from intramuscular (IM) and subcutaneous (SC) sites of injection; with peak plasma concentrations achieved about 1 hour after IM injection .

Orally administered vitamin B12 binds to intrinsic factor (IF) during its transport through the stomach. The separation of Vitamin B12 and IF occurs in the terminal ileum when calcium is present, and vitamin B12 is then absorbed into the gastrointestinal mucosal cells. It is then transported by transcobalamin binding proteins . Passive diffusion through the intestinal wall can occur, however, high doses of vitamin B12 are required in this case (i.e. >1 mg). After the administration of oral doses less than 3 mcg, peak plasma concentrations are not reached for 8 to 12 hours, because the vitamin is temporarily retained in the wall of the lower ileum .

The efficiency of absorption depends on the salt form, the amount administered, the dosing regimen and the size of iron stores. Subjects with normal iron stores absorb 10% to 35% of an iron dose. Those who are iron deficient may absorb up to 95% of an iron dose.

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.

The B vitamins are readily absorbed from the gastrointestinal tract, except in malabsorption syndromes. Pyridoxine is absorbed mainly in the jejunum. The Cmax of pyridoxine is achieved within 5.5 hours.

Ubidecarenone is absorbed from the small intestine into the lymphatics and then it can enter the blood. The hydrophobicity and large molecular weight limit its absorption making it very poor and variable depending on the food intake and the number of lipids presented in the food. The absorption is lower in the presence of an empty stomach and greater in presence of high lipid food diet. The daily dosage of ubidecarenone presents the reach of maximal serum concentration by reaching a plateau after three weeks. The pharmacokinetic properties may vary between different brands but studies have reported an AUC of 11.51 mcg h/ml and a Cmax of 0.32 mcg/ml at a time of 7.9 h.

Half Life

Approximately 6 days (400 days in the liver) .

The total adult body pool consists of 16 to 25 mg of pyridoxine. Its half-life appears to be 15 to 20 days.

The pharmacokinetic properties may vary between different brands but studies have reported a half-life of ubidecarenone of 21.7 h.

Clearance

During vitamin loading, the kidney accumulates large amounts of unbound vitamin B12. This drug is cleared partially by the kidney, however, multiligand receptor megalin promotes the reuptake and reabsorption of vitamin B12 into the body , .

In preclinical studies with intravenous administration of ubidecarenone, it is reported a total clearance of 1.18 ml h/kg which was indicative of a prolonged elimination.

Elimination Route

This drug is partially excreted in the urine . According to a clinical study, approximately 3-8 mcg of vitamin B12 is secreted into the gastrointestinal tract daily via the bile. In patients with adequate levels of intrinsic factor, all except approximately 1 mcg is reabsorbed. When vitamin B12 is administered in higher doses that saturate the binding capacity of plasma proteins and the liver, the unbound vitamin B12 is eliminated rapidly in the urine. The body storage of vitamin B12 is dose-dependent .

After a single oral dose of 100 mcg of folic acid in a limited number of normal adults, only a trace amount of the drug appeared in the urine. An oral dose of 5 mg in 1 study and a dose of 40 mcg/kg of body weight in another study resulted in approximately 50% of the dose appearing in the urine. After a single oral dose of 15 mg, up to 90% of the dose was recovered in the urine. A majority of the metabolic products appeared in the urine after 6 hours; excretion was generally complete within 24 hours. Small amounts of orally administered folic acid have also been recovered in the feces. Folic acid is also excreted in the milk of lactating mothers.

The major metabolite of pyridoxine, 4-pyridoxic acid, is inactive and is excreted in urine

The main elimination route of ubidecarenone is through the bile. After its oral administration, over 60% of the dose is excreted in the feces in the form of unchanged ubidecarenone and a small fraction of the metabolites. In the urine, ubidecarenone is bound to saposin B protein and represents only 8.3% of the total administered dose.
