Description of Letairis
Letairis is a medicine used in the treatment of pulmonary arterial hypertension (PAH) which contains the active ingredient ambrisentan. Endothelins are proteins that increase blood pressure by constricting the blood vessels. Letairis works by blocking the release of this protein into the bloodstream.
Ambrisentan (as Letairis is generically called) is available in two different strengths: Letairis 5mg and Letairis 10mg oral tablets. The inactive constituents of this medicine are: lactose monohydrate, microcrystalline cellulose, croscarmellose sodium and magnesium stearate.
