High Content White Powder Sapropterin Hydrochloride BH4 CAS No.: 69056-38-8

Tetrahydrobiopterin (BH4, THB), also known as sapropterin (INN), is a cofactor of the three aromatic amino acid hydroxylase enzymes, used in the degradation of amino acid phenylalanine and in the biosynthesis of the neurotransmitters serotonin (5-hydroxytryptamine, 5-HT), melatonin, dopamine, norepinephrine (noradrenaline), epinephrine (adrenaline), and is a cofactor for the production of nitric oxide (NO) by the nitric oxide syntheses.

WHAT IS SAPROPTERIN?

Sapropterin is used along with a restricted diet to control blood phenylalanine levels in adults and children 1 month of age and older who have phenylketonuria (PKU; an inborn condition in which phenylalanine may build up in the blood and causes decreased intelligence and a decreased ability to focus, remember, and organize information). Sapropterin will only work for some people who have PKU, and the only way to tell if sapropterin will help a particular patient is to give the medication for a period of time and see whether his or her phenylalanine level decreases. Sapropterin is in a class of medications called cofactors. It works by helping the body to break down phenylalanine so it will not build up in the blood.


HOW TO USE SAPROPTERIN?

Tetrahydrobiopterin is available as a tablet for oral administration in the form of sapropterin dihydrochloride (BH4*2HCL). It was approved for use in the United States as a tablet in December 2007 and as a powder in December 2013. It was approved for use in the European Union in December 2008, Canada in April 2010, and Japan in July 2008. It is sold under the brand names Kuvan and Biopten. The typical cost of treating a patient with Kuvan is US$100,000 per year. BioMarin holds the patent for Kuvan until at least 2024, but Par Pharmaceutical has a right to produce a generic version by 2020.
