Although there was no significant difference of opinion in mean PAP between the two management groups, there was a significant modification in the PVR graduated table with treprostinil therapy (P= 0.0002).
The adverse effects reported included the impression of pain at the introduction site, and 8% of patients discontinued the drug.
An additional controlled original sketch was performed with treprostinil in 26 patients with PAH and showed trends in the betterment of 6 min walk test and in the decrease of PVR. Since 2002, subcutaneous treprostinil has been approved by the FDA for use in the US in patients with PH in NYHA classes II, III and IV; however, because of medical care site pain it can be difficult to achieve the desired dose.
