Ravicti and Zarontin Capsules

• Generic Name: glycerol phenylbutyrate
• Dosage Forms: oral liquid
• Other Brand Names: Ravicti

Ravicti (glycerol phenylbutyrate) binds with other substances in the liver and kidneys to help eliminate nitrogen from the body. Excess nitrogen can cause hyperammonemia, a build-up of ammonia in the blood. Ammonia is very toxic when it circulates in blood and tissues and can cause permanent brain damage, coma, or death.

Ravicti helps prevent a build-up of ammonia in the blood in people with urea cycle disorder. This medicine is used in adults, children and infants. Ravicti will not treat hyperammonemia.

Ravicti is usually given together with a low-protein diet and sometimes dietary supplements.
