RAVICTI for Adults
In adults, RAVICTI® (glycerol phenylbutyrate) Oral Liquid helped keep blood ammonia levels within a normal range* during 12 months of treatment.
- 51 adults took part in the clinical studies
- 7 out of 51 adults (14%) reported a total of 10 hyperammonemic crises
*Range of 6–30 µmol/L.
Do not take RAVICTI if you are allergic to phenylbutyrate. Call your doctor or go to the nearest hospital emergency room if you have symptoms of an allergic reaction, such as wheezing, shortness of breath, cough, low blood pressure, flushing, nausea, or rash while taking RAVICTI.
RAVICTI helps control ammonia levels throughout the day and night
- A team of doctors conducted 2 short-term clinical studies (one for 2 weeks and the other for 4 weeks) to learn if RAVICTI, like the UCD medication sodium phenylbutyrate, helps control ammonia levels from going up and down
- To do this, the doctors measured ammonia levels in patients taking RAVICTI or sodium phenylbutyrate over 24 hours
- In these short-term clinical studies, no hyperammonemic crises were reported in adult patients with UCDs who were treated with RAVICTI
- The results showed that RAVICTI was similar to sodium phenylbutyrate in safely controlling ammonia levels for 24 hours. The chart below shows how RAVICTI keeps ammonia levels consistent throughout the day
