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]
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]
Pyritinol also called pyridoxine disulfide or pyrithioxine (European drug names Encephabol, Encefabol, Cerbon 6) is a semi-synthetic water-soluble analog of vitamin B 6 (Pyridoxine HCl). It was produced in 1961 by Merck Laboratories by bonding 2 vitamin B 6 compounds ( pyridoxine ) together with a disulfide bridge.
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.
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.
