Sapropterin

Sapropterin is a medication used to help people with phenylketonuria (PKU), a genetic condition that affects how the body processes an amino acid called phenylalanine. In some people with PKU, sapropterin works by increasing the activity of the enzyme responsible for breaking down phenylalanine, reducing its levels in the blood. This can help prevent the harmful effects of high phenylalanine, such as brain damage and developmental issues. Sapropterin is usually prescribed along with a special diet to manage PKU effectively.
