Orenitram helps patients with pulmonary arterial hypertension (PAH) categorized as WHO Group 1. It is used to slow the progression of the disease and improve a patient's exercise capacity. This medication is primarily prescribed for individuals with functional class II-III symptoms, including those with idiopathic, heritable, or connective tissue disease-related PAH.

How ORENITRAM Works

This drug works by mimicking prostacyclin to directly dilate the arterial vascular beds in the lungs and throughout the body. It also helps by preventing platelets from clumping and inhibiting the growth of smooth muscle cells. These actions collectively help manage the vascular issues associated with the condition.
