Urea cycle disorder agents are used to treat conditions like high ammonia levels and urea cycle disorders. These medications help your body remove excess ammonia, which can be toxic if it builds up. They work by providing other pathways to clear ammonia from the bloodstream. Some of these medications come in different forms, such as oral and injectable. Examples include sodium phenylbutyrate (Buphenyl), glycerol phenylbutyrate (Ravicti), and sodium phenylacetate/sodium benzoate. You can choose the form that best fits your needs.
