Have you or someone you know ever been told by a doctor that they have a urea cycle disorder, or Urea Cycle Disorder ( UCD ) ? When this happens, the level of a toxic substance called ammonia in our body can increase dangerously. This is a very serious condition.

So, what this Sodium Phenylbutyrate drug does is help your body reduce this excess ammonia. To be precise, this drug activates other pathways in the body that remove ammonia. This reduces the risk of developing those dangerous health problems.
