Treprostinil — Uses, Dosage, Side Effects & Safety

Drug class: Prostacyclin analog; Vasodilator; Antihypertensive (pulmonary)

Overview

Treprostinil is a medication used to treat pulmonary arterial hypertension (PAH), a condition where there is high blood pressure in the arteries of the lungs. It helps improve exercise ability and symptoms in people with PAH by relaxing blood vessels in the lungs, making it easier for the heart to pump blood through them. Treprostinil works by mimicking the effects of prostacyclin, a natural substance in the body that widens (dilates) blood vessels and prevents blood clots. This reduces the workload on the heart and improves oxygen delivery throughout the body. Key points for patients: Treprostinil can be given as an injection, inhaled, or taken as a tablet. It requires regular dosing and careful monitoring. Side effects are common, but many are mild and manageable. Always follow your healthcare provider’s instructions and report any unusual symptoms.
