What is Vyndamax?
Vyndamax is an oral prescription medicine that may be used to reduce death or hospitalization related to heart problems in adults with cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis (ATTR-CM). Vyndamax is a transthyretin stabilizer.
Vyndamax works by stabilizing abnormal transthyretin, a protein associated with ATTR-CM. This mechanism of action of Vyndamax prevents the formation of harmful amyloid protein deposits in the heart, slowing disease progression.
Vyndamax was FDA approved on May 3, 2019. There is no Vyndamax generic.
Vyndaqel Vs Vyndamax
The difference between Vyndaqel and Vyndamax is the form of the active ingredient they both contain, tafamidis. Vyndaqel has the micronized tafamidis meglumine salt, while Vyndamax has the free acid form of tafamidis.
Both forms work the same way in the body, but Vyndaqel contains a smaller amount of tafamidis, and needs to be taken 4 times a day. Vyndamax only needs to be taken 1 time per day.
