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.
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.
Pyridoxamine was marketed as a dietary supplement, often as the hydrochloride salt, pyridoxamine dihydrochloride.However, in the United States, the FDA ruled in January 2009 that pyridoxamine must be regulated as a pharmaceutical drug because it is the active ingredient in Pyridorin, a drug designed by Biostratum, Inc., to prevent the progression of diabetic nephropathy.
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]
Metadoxine is an ion pair salt of pyridoxine and pyrrolidone carboxylate (PCA). [1] Pyridoxine (vitamin B 6) is a precursor of coenzymes including pyridoxal 5’-phosphate (PLP), which accelerates the metabolic degradation of ethanol and prevents adenosine triphosphate (ATP) inactivation by acetaldehyde.
