Nityr

Nityr is a medicine used to treat hereditary tyrosinaemia type 1 (HT-1). This is a rare disease in which the body is unable to completely break down the amino acid tyrosine and, as a result, harmful substances are formed, causing serious liver problems and liver cancer. Nityr is used together with a diet that restricts the intake of the amino acids tyrosine and phenylalanine. These amino acids are normally found in proteins in foods and drinks. Nityr contains the active substance nitisinone and is a ‘generic medicine’. This means that Nityr contains the same active substance and works in the same way as a ‘reference medicine’ already authorised in the EU called Orfadin.
