Calcium glycerophosphate is a Calcium salt of glycerophosphoric acid that forms a white, fine, slightly hygroscopic powder. The commercial product is a mixture of calcium beta-, and D-, and L -alpha-glycerophosphate. By FDA, calcium glycerophosphate is considered a generally recognized as safe (GRAS) food ingredient as a nutrient supplement (source of calcium or phosphorus), or in food products such as gelatins, puddings, and fillings. It is also present in dental or oral hygiene products due to its cariostatic effects. It is suggested that calcium glycerophosphate promotes plaque-pH buffering, elevation of plaque Calcium and phosphate levels and direct interaction with dental mineral .

It is thought that calcium glycerophosphate may act through a variety of mechanisms to produce an anti-caries effect . These include increasing acid-resistance of the enamel, increasing enamel mineralization, modifying plaque, acting as a pH-buffer in plaque, and elevating Calcium and phosphate levels.

When used as an electrolyte replacement, calcium glycerophosphate donates Calcium and inorganic phosphate. Calcium glycerophosphate is preferable to calcium phosphate due to its increased solubility. Compared to combination calcium gluconate and potassium phosphate, calcium glycerophosphate produces greater phosphate retention which allows for increased Calcium retention and ultimately greater incorporation of the ions into bone structure .

An important compound functioning as a component of the coenzyme NAD. Its primary significance is in the prevention and/or cure of blacktongue and pellagra. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake.

Pyridoxine is a water-soluble vitamin which functions in the metabolism of carbohydrates, proteins and fats. It is essential in Hb formation and GABA synthesis within the CNS. It also aids in the release of glycogen stored in the liver and muscles.

Vitamin B6 (pyridoxine) is a water-soluble vitamin used in the prophylaxis and treatment of vitamin B6 deficiency and peripheral neuropathy in those receiving isoniazid (isonicotinic acid hydrazide, INH). Vitamin B6 has been found to lower systolic and diastolic blood pressure in a small group of subjects with essential hypertension. Hypertension is another risk factor for atherosclerosis and coronary heart disease. Another study showed pyridoxine hydrochloride to inhibit ADP- or epinephrine-induced platelet aggregation and to lower total cholesterol levels and increase HDL-cholesterol levels, again in a small group of subjects. Vitamin B6, in the form of pyridoxal 5'-phosphate, was found to protect vascular endothelial cells in culture from injury by activated platelets. Endothelial injury and dysfunction are critical initiating events in the pathogenesis of atherosclerosis. Human studies have demonstrated that vitamin B6 deficiency affects cellular and humoral responses of the immune system. Vitamin B6 deficiency results in altered lymphocyte differentiation and maturation, reduced delayed-type hypersensitivity (DTH) responses, impaired antibody production, decreased lymphocyte proliferation and decreased interleukin (IL)-2 production, among other immunologic activities.

Sodium glycerophosphate is one of several glycerophosphate salts. It is used clinically to treat or prevent low phosphate levels . Glycerophosphate is hydrolyzed to inorganic phosphate and glycerol in the body . The extent of this reaction is dependent on the activity of serum alkaline phosphatases.

Glycerophosphate acts as a source of inorganic phosphate through hydrolysis .

Uses

Calcium glycerophosphate is an medication used to treat low levels of phosphate or calcium, as well as an ingredient in dental products to prevent dental caries.

Calcium glycerophosphate is found in OTC dental products such as toothpastes for the prevention of dental caries. As OTC products these do not have an official indication.

In prescription products it is indicated as a Calcium or phosphate donor for replacement or supplementation in patients with insufficient Calcium or phosphate.

Nicotinamide is an ingredient found in a variety of cosmetic products.

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).

Sodium glycerophosphate is a medication used to treat hypophosphatemia.

Sodium glycerophosphate is indicated for use as a source of phosphate in total parenteral nutrition . It is used in combination with amino acids, dextrose, lipid emulsions, and other electrolytes.

How Viophos-b 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 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).

Sodium glycerophosphate acts as a donor of inorganic phosphate . See Monopotassium phosphate for a description of phosphate's role in the body.

Volume of Distribution

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.

Elimination Route

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.

Peak serum phosphate concentration is reached in 4h .

Half Life

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

Inorganic phosphate has a half-life of elimination of 2.06h .

Elimination Route

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

Inorganic phosphate produced is eliminated in the urine . There may be a very small amount of glycerophosphate excreted in the urine unchanged.

Pregnancy & Breastfeeding use

Category A: Controlled studies in women fail to demonstrate a risk to the foetus in the 1st trimester (and there is no evidence of a risk in later trimesters), and the possibility of foetal harm remains remote.
