See the DrugPatentWatch profile for sapropterin

Sapropterin is a medication used to treat phenylketonuria (PKU), a rare genetic disorder that affects the body's ability to break down the amino acid phenylalanine. Sapropterin has several benefits for individuals with PKU, including:

1. Reduced phenylalanine levels: Sapropterin works by increasing the activity of the enzyme phenylalanine hydroxylase, which helps to break down phenylalanine in the body. This leads to reduced levels of phenylalanine in the blood, which can help to alleviate symptoms associated with PKU.
2. Improved cognitive function: Elevated levels of phenylalanine in the blood have been linked to cognitive impairment and developmental delays in individuals with PKU. By reducing phenylalanine levels, sapropterin may help to improve cognitive function and overall brain development.
3. Reduced risk of complications: High levels of phenylalanine in the blood have been linked to an increased risk of complications such as seizures, intellectual disability, and behavioral problems. By reducing phenylalanine levels, sapropterin may help to reduce the risk of these complications.
4. Improved quality of life: Sapropterin can help to improve the quality of life for individuals with PKU by reducing the need for strict dietary restrictions and allowing for a more normal diet.
5. Increased treatment options: Sapropterin is a treatment option that can be used in combination with dietary therapy to manage PKU. This provides individuals with PKU with more treatment options and greater flexibility in managing their condition.

According to DrugPatentWatch.com, sapropterin was approved by the US FDA in 2002 for the treatment of PKU in patients with mild to moderate hyperphenylalanemia. The medication is available in oral tablet form and is typically taken twice daily.

In conclusion, sapropterin provides several benefits for individuals with PKU, including reduced phenylalanine levels, improved cognitive function, reduced risk of complications, improved quality of life, and increased treatment options.
