WHAT TEGSEDI IS AND WHAT IT IS USED FOR
Tegsedi contains the active substance inotersen. Inotersen is used to
treat adults with hereditary
transthyretin amyloidosis. Hereditary transthyretin amyloidosis is a
genetic disease, which causes
build-up of small fibres of a protein called transthyretin in the
organs of your body stopping them from
working properly. Tegsedi is used when the disease is causing symptoms
of polyneuropathy (nerve
damage).
Inotersen, is a type of medicine called an antisense oligonucleotide
inhibitor. It works by reducing
production of transthyretin by the liver and so lowers the risk of
fibres of transthyretin being deposited
in body organs and causing symptoms.
2.
