Uses For This Medicine
Iloprost inhalation is used to treat the symptoms of pulmonary arterial hypertension (PAH). This is high blood pressure that occurs in the main artery that carries blood from the right side of the heart (the ventricle) to the lungs. When high blood pressure is present, the blood vessels in the lungs are tighter and have smaller openings. This means the right ventricle must work harder to pump enough blood through the lungs. Iloprost is a synthetic (man-made) type of hormone called prostacyclin. Prostacyclin is produced in the lungs and keeps the blood vessels relaxed. People with PAH do not make enough prostacyclin in the lungs. Iloprost will cause the blood vessels to relax, which increases the supply of blood to the lungs and reduces the workload of the heart.
Iloprost is available only with your doctor's prescription.
Before Using This Medicine

Tell your doctor if you have ever had any unusual or allergic reaction to iloprost or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.
