Pyridoxine (PN) [4] is a form of vitamin B 6 found commonly in food and used as a dietary supplement. As a supplement it is used to treat and prevent pyridoxine deficiency , sideroblastic anaemia , pyridoxine-dependent epilepsy , certain metabolic disorders , side effects or complications of isoniazid use, and certain types of mushroom ...

Pyridoxine is converted to pyridoxal phosphate via two enzymes, pyridoxal kinase and pyridoxine 5′-phosphate oxidase. High levels of pyridoxine can inhibit these enzymes. As pyridoxal phosphate is the active form of vitamin B 6, this saturation of pyridoxine could mimic a deficiency of vitamin B 6. [23] [27]
Pyridoxal phosphate (PLP, pyridoxal 5'-phosphate, P5P), the active form of vitamin B 6, is a coenzyme in a variety of enzymatic reactions. The International Union of Biochemistry and Molecular Biology has catalogued more than 140 PLP-dependent activities, corresponding to ~4% of all classified activities. [5]
The combination of doxylamine and pyridoxine is available in the form of extended-and delayed-release oral tablets containing 10 to 20 mg doxylamine succinate and 10 to 20 mg pyridoxine hydrochloride. [22] Doxylamine alone is available over-the-counter, whereas doxylamine in combination with pyridoxine is a prescription-only medication. [22]
The term vitamin does not include the three other groups of essential nutrients: minerals, essential fatty acids, and essential amino acids. [2] Major health organizations list thirteen vitamins: [3] [4] [5] Vitamin A (all-trans-retinols, all-trans-retinyl-esters, as well as all-trans-β-carotene and other provitamin A carotenoids) Vitamin B 1
Pyridoxine 5′-phosphate oxidase is an enzyme, encoded by the PNPO gene, [1] [2] [3] that catalyzes several reactions in the vitamin B 6 metabolism pathway. Pyridoxine 5′-phosphate oxidase catalyzes the final, rate-limiting step in vitamin B 6 metabolism, the biosynthesis of pyridoxal 5′-phosphate, the biologically active form of vitamin B 6 which acts as an essential cofactor.

Pyridoxine/doxylamine, sold under the brand name Diclectin among others, is a combination of pyridoxine hydrochloride (vitamin B 6) and doxylamine succinate.It is generally used for nausea and vomiting of pregnancy (morning sickness); even though its efficacy has not been proven and subsequent research has led to the removal of recommendations in medical journals.
