Subcutaneous treatment options are delivered through a portable infusion pump to open up the blood vessels and ease the symptoms of PH:
- Subcutaneous treprostinil (Remodulin®) – approved in Canada in 2002
Although all of the above-mentioned medications help to alleviate the symptoms of PH and slow its progression, they do not provide a cure. As the disease progresses, treating physicians prescribe the available treatments alone or in combination to help alleviate the symptoms and slow progression. Once a combination of treatments is no longer effective, lung transplantation may be considered.
