A. Ventavis (iloprost) is the first inhaled treatment for PH. It was FDA-approved in 1994. Ventavis directly helps open the narrowed blood vessels in the lungs. PH patients on Ventavis have shown an increase in exercise ability and less shortness of breath. Ventavis is inhaled at least 6 times a day, and time taken for each inhalation is 6-10 minutes, depending on the patient.
