Pyridoxamine is one of the compounds composing vitamin B6, along with pyridoxal and pyridoxine. Pyridoxamine is converted to the biologically active form, pyridoxal 5-phosphate, and inhibits formation of advanced glycation endproducts.
Pyridoxamine is based on a pyridine ring, with hydroxyl, methyl, aminomethyl, and hydroxymethyl substituents. It differs from pyridoxine by the subsitituent at the 4-position.
Pyridoxamine is used 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 to prevent the progression of diabetic nephropathy.[1] As a consequence, pyridoxamine can no longer be marketed in the United States as a dietary supplement.
