WHAT PHEBURANE IS AND WHAT IT IS USED FOR
PHEBURANE contains the active substance sodium phenylbutyrate which is
used to treat
patients of all ages with urea cycle disorders. These rare disorders
are due to a deficiency of
certain liver enzymes which are necessary to eliminate waste nitrogen
in the form of ammonia.
Nitrogen is a building block of proteins, which are an essential part
of the food we eat. As the
body breaks down protein after eating, waste nitrogen, in the form of
ammonia, accumulates
because the body cannot eliminate it. Ammonia is especially toxic for
the brain and leads, in
severe cases, to reduced levels of consciousness and to coma.
This medicine helps the body to eliminate waste nitrogen, reducing the
amount of ammonia in
your body. However PHEBURANE must be used along with a diet reduced in
proteins,
designed especially for you by the doctor and the dietician. You must
follow this diet carefully.

WHAT YOU NEED TO KNOW BEFORE YOU TAKE PHEBURANE

disease (complete enzyme deficiencies, presenting
within the first 28 days of life). It is also indicated in patients
with
_late-onset _
disease (partial enzyme
deficiencies, presenting after the first month of life) who have a
history of hyperammonaemic
encephalopathy.

The daily dose should be individually adjusted according to the
patient’s protein tolerance and the
daily dietary protein intake needed to promote growth and development.
The usual total daily dose of sodium phenylbutyrate in clinical
experience is:

450 - 600 mg/kg/day in neonates, infants and children weighing less

Plasma levels of ammonia, arginine, essential amino acids (especially
branched chain amino acids),
carnitine and serum proteins should be maintained within normal
limits. Plasma glutamine should be
maintained at levels less than 1,000 μmol/L.
