Which statement correctly describes treprostinil among prostacyclin analogues?

Treprostinil is indeed available in multiple formulations, including parenteral (intravenous and subcutaneous), inhaled, and oral forms. This versatility is one of the key features that differentiate it from some other prostacyclin analogues, which may not have the same range of administration routes.

The availability of these various formulations allows for flexibility in patient management, catering to individual tolerability and treatment preferences. For instance, patients with pulmonary arterial hypertension can benefit from the inhaled formulation for targeted therapy, while those who cannot tolerate injections may opt for the oral version. This wide range of delivery methods is significant for optimizing adherence and treatment efficacy in clinical practice.

Understanding the indications and appropriate use of these formulations is crucial for effective patient care in cardiology, especially in conditions like pulmonary arterial hypertension.
