WHAT EXTAVIA IS AND WHAT IT IS USED FOR
WHAT EXTAVIA IS
Extavia is a type of medicine known as interferon used to treat
multiple sclerosis. Interferons are
proteins produced by the body that help it fight against attacks on
the immune system such as viral
infections.
HOW EXTAVIA WORKS
MULTIPLE SCLEROSIS (MS)
is a long-term condition that affects the central nervous system
(CNS),
particularly the functioning of the brain and spinal cord. In MS,
inflammation destroys the protective
sheath (called myelin) around the nerves of the CNS and stops the
nerves from working properly. This
is called demyelination.
The exact cause of MS is unknown. An abnormal response by the body’s
immune system is thought to
play an important part in the process which damages the CNS.
THE DAMAGE TO THE CNS
can occur within an MS attack (relapse). It can cause temporary
disability,
such as difficulty walking. Symptoms may disappear completely or
partly.
Interferon beta-1b has been shown to change the response of the immune
system and to help to reduce
disease activity.
