Flolan, generically known as Epoprostenol, is a potent medication primarily used in the treatment of pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries that supply blood to the lungs. It works by relaxing and widening the blood vessels in the lungs, which decreases the blood pressure within these vessels. Flolan is administered directly into the bloodstream through an intravenous (IV) infusion, requiring careful handling and monitoring due to its short half-life and the need for continuous delivery. This medication can significantly improve symptoms such as shortness of breath and exercise capacity in individuals with PAH, enhancing their quality of life. Due to its critical nature and administration method, Flolan treatment is typically managed by healthcare professionals specialized in treating pulmonary hypertension.
