When working with ambrisentan, ambrisentan, a prescription drug that blocks endothelin receptors to lower blood pressure in the lungs. Also known as Letairis, it is primarily used to treat pulmonary arterial hypertension, a progressive disease that raises the pressure in the pulmonary arteries and strains the right side of the heart. The drug belongs to the class of endothelin receptor antagonists, or ERAs, which work by preventing the constricting action of endothelin‑1, a peptide that narrows blood vessels. Understanding how ambrisentan fits into the broader ERA family helps you compare it with older options like bosentan and newer agents such as macitentan. By grasping these relationships, you can see why clinicians choose ambrisentan for patients who need once‑daily dosing, fewer drug‑interaction warnings, and a better liver‑safety profile.
Ambrisentan’s dosing is straightforward: most adults start with 10 mg once daily, with the option to increase to 15 mg if blood pressure remains high and side effects are manageable. The drug’s main safety concerns revolve around liver enzyme elevations, anemia, and potential pregnancy risks – it’s a Category X medication, so reliable contraception is mandatory for women of child‑bearing age. Patients often wonder how ambrisentan stacks up against other PAH therapies. In head‑to‑head trials, ambrisentan showed comparable improvements in six‑minute walk distance when paired with phosphodiesterase‑5 inhibitors like sildenafil, while offering a simpler dosing regimen than bosentan, which requires twice‑daily administration and routine liver monitoring. Moreover, ambrisentan does not significantly affect the metabolism of many common drugs, making it a safer choice for patients on complex regimens.
