WHAT ATRYN IS AND WHAT IT IS USED FOR
ATryn contains antithrombin alfa which is similar to the naturally
occurring human antithrombin. In the
body, antithrombin blocks thrombin, a substance that plays a central
role in the process of blood clotting.
If you have an inborn deficiency of antithrombin, your blood level of
antithrombin is lower than normal.
This may result in a higher tendency to form clots in your blood
vessels. This may be in the vessels of your
legs (deep vein thrombosis) or in other vessels of your body
(thromboembolism). Around major surgical
procedures this tendency to clot is even more increased. Therefore, it
is important that your antithrombin
blood level be maintained at sufficient levels in these situations.
This medicine is used in patients who have ‘congenital antithrombin
deficiency’ (inherited low levels of the
protein antithrombin). It is used when the patients are having
surgery, to prevent problems due to the
formation of blood clots in the vessels. It is normally given in
association with heparin or l
