EXPERIENCE. INNOVATION. SUPPORT.
For 2 decades, patients and their healthcare providers have trusted Remodulin to help reduce PAH symptoms and help patients have more active lives.1
United Therapeutics has been consistently manufacturing Remodulin, the brand name of generic treprostinil injection, since its introduction in 2002.1 During that time, there have been no supply interruptions for Remodulin, due to our commitment to hold a 2-year supply of inventory at all times.
Our story
Remodulin is produced by United Therapeutics Corporation, a medical biotechnology company, founded by Martine and Bina Rothblatt in 1996, after their daughter’s PAH was diagnosed. United Therapeutics was born from a very personal and passionate desire to develop medicines that could help their daughter and others suffering from this rare disease.
United Therapeutics is committed to innovation in the treatment of PAH and helping patients live with PAH. United Therapeutics supports HCPs and patients who are being treated with branded Remodulin with support programs, such as SPmix, financial assistance, referral support, and Specialty Pharmacy nursing support.

State’s or territory’s DAW requirements
A state’s or territory’s DAW requirements may help you preserve your choice for branded medication if you decide that it is the right option for your patients.
Specific wording for DAW may vary by state, such as “Brand Medically Necessary” and “Do Not Substitute.”
Use our DAW Requirements Guide to find your specific state or territory requirements.
PLEASE NOTE: The rules for writing DAW will vary by state. Our DAW Requirements Guide can help you find your specific state or territory requirements. Be sure to include the required language for your state to ensure that branded product is dispensed.
DAW=dispense as written; PAH=pulmonary arterial hypertension.
Important Safety Information
Warnings and Precautions
- Chronic intravenous (IV) infusions of Remodulin delivered using an external infusion pump with an indwelling central venous catheter are associated with the risk of blood stream infections (BSIs) and sepsis, which may be fatal. Therefore, continuous subcutaneous (SC) infusion is the preferred mode of administration.
- Avoid abrupt withdrawal or sudden large reductions in dosage of Remodulin, which may result in worsening of PAH symptoms.
- Titrate slowly in patients with hepatic or renal insufficiency, because such patients will likely be exposed to greater systemic concentrations relative to patients with normal hepatic or renal function.
- Remodulin is a pulmonary and systemic vasodilator. In patients with low systemic arterial pressure, treatment with Remodulin may produce symptomatic hypotension.
- Remodulin inhibits platelet aggregation and increases the risk of bleeding.
Adverse Reactions
- In clinical studies of SC Remodulin infusion, the most common adverse events reported were infusion site pain and infusion site reaction (redness, swelling, and rash). These symptoms were sometimes severe and sometimes required treatment with narcotics or discontinuation of Remodulin. The IV infusion of Remodulin with an external infusion pump has been associated with a risk of blood stream infections, arm swelling, paresthesias, hematoma, and pain. Other common adverse events (≥3% more than placebo) seen with either SC or IV Remodulin were headache (27% vs. 23%), diarrhea (25% vs. 16%), nausea (22% vs. 18%), rash (14% vs. 11%), jaw pain (13% vs. 5%), vasodilatation (11% vs. 5%), edema (9% vs. 3%), and hypotension (4% vs. 2%).
Drug Interactions
- Remodulin dosage adjustment may be necessary if inhibitors or inducers of CYP2C8 are added or withdrawn.
Specific Populations
- In patients with mild or moderate hepatic insufficiency, decrease the initial dose of Remodulin to 0.625 ng/kg/min of ideal body weight, and monitor closely. Remodulin has not been studied in patients with severe hepatic insufficiency.
- Safety and effectiveness of Remodulin in pediatric patients have not been established.
- It is unknown if geriatric patients respond differently than younger patients. Caution should be used when selecting a dose for geriatric patients.
- There are no adequate and well-controlled studies with Remodulin in pregnant women. It is not known whether treprostinil is excreted in human milk or if it affects the breastfed infant or milk production.
Indication
Remodulin is a prostacyclin vasodilator indicated for the treatment of pulmonary arterial hypertension (PAH; WHO Group 1) to diminish symptoms associated with exercise. Studies establishing effectiveness included patients with NYHA Functional Class II-IV symptoms and etiologies of idiopathic or heritable PAH (58%), PAH associated with congenital systemic-to-pulmonary shunts (23%), or PAH associated with connective tissue diseases (19%).
In patients with PAH requiring transition from epoprostenol, Remodulin is indicated to diminish the rate of clinical deterioration. Consider the risks and benefits of each drug prior to transition.
