Letairis (ambrisentan) prevents thickening of the blood vessels, especially those in the lungs and heart. Ambrisentan also lowers blood pressure in your lungs, helping your heart pump blood more efficiently.

Letairis is sometimes used with a medicine called tadalafil (Adcirca).

For women, Letairis is available only from a certified pharmacy under a special program. You must be registered in the program and sign agreements to use birth control and undergo pregnancy and blood testing.
