Sapropterin dihydrochloride: A new drug and a new concept in the management of phenylketonuria

Drugs of Today, 2010
Phenylketonuria (PKU) is characterized by persistent hyperphenylalaninemia, due to mutations in the gene coding for phenylalanine hydroxylase (PAH). If untreated, patients develop profound mental retardation. The principal treatment for PKU is lifelong dietary phenylalanine restriction, requiring the administration of special phenylalanine-free protein

Relative bioavailability of sapropterin from intact and dissolved sapropterin dihydrochloride tablets and the effects of food: A randomized, open-label, crossover study in healthy adults

Clinical Therapeutics, 2010
Phenylketonuria (PKU) is an autosomal recessive metabolic disorder characterized by hyperphenylalaninemia in association with neurocognitive and neuromotor impairment. Sapropterin dihydrochloride (hereafter referred to as sapropterin) administered orally as dissolved tablets is approved by the US Food and Drug Administration for hyperphenylalaninemia ...

START, a double blind, placebo-controlled pharmacogenetic test of responsiveness to sapropterin dihydrochloride in phenylketonuria patients

Molecular Genetics and Metabolism, 2012
Sapropterin dihydrochloride, a synthetic tetrahydrobiopterin (BH4), works as a chaperone of phenylalanine hydroxylase (PAH) in phenylketonuria (PKU) to facilitate and stabilize folding of PAH into its most active conformation. No standard pharmacogenetic tests exist to identify responsive genotypes.

Safety of extended treatment with sapropterin dihydrochloride in patients with phenylketonuria: Results of a phase 3b study

Molecular Genetics and Metabolism, 2011
Phenylketonuria (PKU) results from impaired breakdown of phenylalanine (Phe) due to deficient phenylalanine hydroxylase (PAH) activity. Sapropterin dihydrochloride (sapropterin, Kuvan®) is the only US- and EU-approved pharmaceutical version of naturally occurring 6R-BH(4), the cofactor required for PAH activity.

In Vitro Stability of Sapropterin Dihydrochloride From Crushed Tablets Mixed in Applesauce, Pudding, and Infant Formula

ICAN: Infant, Child, & Adolescent Nutrition, 2009
Sapropterin is approved to reduce blood phenylalanine levels in patients with hyperphenylalaninemia due to tetrahydrobiopterin-responsive phenylketonuria. The current Food and Drug Administration—approved labeling states that sapropterin tablets should be dissolved in 4 to 8 oz of water or apple juice; however, numerous requests for information ...

Sapropterin dihydrochloride, 6-R-L-erythro-5,6,7,8-tetrahydrobiopterin, in the treatment of phenylketonuria

Expert Opinion on Investigational Drugs, 2008
Sapropterin dihydrochloride, 6-R-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) is being introduced in the US for treatment of phenylketonuria (PKU). This compound has been in use in Europe to treat mild forms of PKU. Tetrahydrobiopterin is the cofactor in the hydroxylation reaction of the three aromatic amino acids phenylalanine, tyrosine and tryptophan.
