| Description |
Pyridoxine hydrochloride provides pyridoxine, which is also known as vitamin B6. Vitamin B6 is naturally found in foods such as cereals, beans, vegetables, liver, meat, and eggs. Vitamin B6 functionalizes as a coenzyme in the metabolism of protein, carbohydrate, and fat. Vitamin 6 is needed to maintain the health of nerves, skin, and red blood cells.
Pyridoxine is used to prevent or treat vitamin B6 deficiency caused by inadequate dietary intake. It is also used to treat drug induced deficiency in patients taking isoniazid or oral contraceptives. |

| Uses |
Vitamin B6, a water-soluble vitamin with a solubility of 1 g in 5 ml of water. It functions in the utilization of protein and is an essential nutrient in enzyme reactions. It is necessary for proper growth. During processing, there is a loss due to leaching of the vitamin in water. It is destroyed by high temperatures, high irradiation, and exposure to light. During storage, loss increases with temperature and storage time. It is found in liver, eggs, and meats. |
| Definition |
ChEBI: A hydroxymethylpyridine with hydroxymethyl groups at positions 4 and 5, a hydroxy group at position 3 and a methyl group at position 2. The 4-methanol form of vitamin B6, it is converted intoto pyridoxal phosphate which is a coenzyme f r synthesis of amino acids, neurotransmitters, sphingolipids and aminolevulinic acid. |

Pyridoxine (vitamin B6) is listed in theWHO Model List of Essential Drugs. |
| General Description |
The discovery of vitamin B6 is generally ascribed to Paul Gy?rgy who first realized there was a vitamin that was distinctly different from vitamin B2 in 1934. Pyridoxine (PN) is the C4 hydroxymethyl derivative, pyridoxal (PL) is the C4 formyl derivative and pyridoxamine (PM) is the C4 aminomethyl derivative of 5-(hydroxymethyl)- 2-methylpyridin-3-ol). Each of these are also converted to their corresponding 5'-phosphate derivatives referred to as pyridoxine 5'-phosphate (PNP), pyridoxal 5'-phosphate (PLP), and pyridoxamine 5'-phosphate (PMP), respectively . Because of their ability to interconvert, all are considered active forms of vitamin B6 in vivo. Although PLP is the major coenzyme form, PMP can also function as a coenzyme primarily in aminotransferases. The major metabolite is 4-pyridoxic acid, which is excreted in the urine. |
| Clinical Use |
Pyridoxine is indicated in the treatment and prevention of known or suspected vitamin B6deficiency, which is most likely to occur in the setting of alcoholism in developed countries. At least seven genetic disorders that result in a vitamin B6 deficiency syndrome in the presence of an adequate dietary intake have been identified. These result from defects in enzymes that are responsible for the bioactivation or utilization of vitamin B6. |
| Safety Profile |
Moderately toxic by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Human systemic effects: ataxia, local anesthetic, paresthesia. When heated to decomposition it emits toxic fumes of Nox |

This nutritionally essential factor (FWfree base = 169.18 g/mol; CAS 65-23-6), also called vitamin B6 and pyridoxol, is a white solid that is typically supplied as the hydrochloride (the two pKa values are 4.94 and 8.89). (Note: The term vitamin B6 actually refers to a mixture of pyridoxine, pyridoxal, and pyridoxamine.) Pyridoxine is stable in light and air, but is somewhat photolabile in neutral and alkaline solutions. It is soluble in water (1 g/4.5 mL) and has lmax values at 253 and 325 nm at pH 7 in phosphate buffer (e = 3700 and 7100 M–1cm–1, respectively). Pyridoxine is a substrate of the reactions catalyzed by pyridoxine 4-dehydrogenase, pyridoxine 4-oxidase, pyridoxine 5-dehydrogenase, and pyridoxine 5'-O-b-D-glucosyltransferase. Target(s): alanine racemase; arginine decarboxylase; dextransucrase; b-fructofuranosidase, or invertase; glycogen phosphorylase b; hydroxymethylpyrimidine kinase, also alternative substrate; Ki = 2.7 μM; pyridoxal dehydrogenase; pyridoxamine-5-phosphate oxidase; pyridoxamine:pyruvate aminotransferase; and tyrosinase. |
