Used primarily in the treatment of pulmonary arterial hypertension (PAH), this compound helps to reduce high blood pressure in the lungs by dilating blood vessels and improving the ability to exercise. It is administered via continuous subcutaneous or intravenous infusion, allowing for steady delivery to maintain vascular effects. The formulation supports long-term management of symptoms, helping to slow disease progression and enhance patient quality of life. Its stability in solution makes it suitable for use with portable infusion pumps, enabling outpatient treatment.
