1.
WHAT AMMONAPS IS AND WHAT IT IS USED FOR
AMMONAPS is prescribed to patients with urea cycle disorders. Patients
with these rare disorders
have a deficiency of certain liver enzymes and are therefore unable to
eliminate nitrogen waste.
Nitrogen is a building block of proteins, because of this, there is a
build up of nitrogen in the body
after eating protein. Nitrogen waste, in the form of ammonia, is
especially toxic for the brain and
leads, in severe cases, to reduced levels of consciousness and to
coma.
AMMONAPS helps the body to eliminate nitrogen waste, reducing the
amount of ammonia in your
body.
