How much does Ravicti cost?
Developed by Horizon Therapeutics, RAVICTI costs $793,632 for a year of treatment.
What is sodium phenylbutyrate used for?
Sodium phenylbutyrate is used together with a proper diet to help treat urea cycle disorders (including a specific liver enzyme deficiency) that help remove ammonia (nitrogen) from the body.
How common is urea cycle disorder?
Urea cycle disorders occur in about one in 30,000 newborns. Urea cycle disorders are genetic. Genes give the body instructions on how to break down protein. We usually have two copies of each gene, and most UCD only occur when a person inherits a changed gene from both parents.
What is hyperammonemia?

- Keep using this medicine even if you feel well.
Which urea cycle disorder is most common?
Specific Urea Cycle Disorders Carbamoylphosphate synthetase I deficiency (CPS1 deficiency) is the most severe of the urea cycle disorders. Individuals with complete CPS1 deficiency rapidly develop hyperammonemia in the newborn period.
How do you manage urea cycle disorders?

What are the types of hyperammonemia?
Isovaleric acidemia. Propionic acidemia. Carnitine palmitoyltransferase II deficiency. Transient hyperammonemia of the newborn, specifically in the preterm.
What drugs can cause hyperammonemia?
Drug-induced hyperammonemia can result from interference with the urea cycle or enhancement of renal release of ammonia into the systemic circulation. Valproic acid is the most well known [48], but others include carbamazepine [49], sulfadiazine [50], ribavirin [51], salicylates [52], and glycine [53].
