Transitioning your patients from Flolan® (epoprostenol sodium)1
Transitioning from Flolan to SC Remodulin1,2
Subcutaneous Remodulin has been demonstrated to diminish the rate of clinical deterioration* in patients requiring transition from Flolan.
- An 8-week, multicenter, randomized (2:1), placebo-controlled, withdrawal trial of 22 patients stable on epoprostenol therapy who were started on SC Remodulin or placebo
- Time to clinical deterioration* was the primary endpoint of this trial
- Safety findings were consistent with previous clinical trials of SC Remodulin
*Clinical deterioration was defined as an increase in Flolan dose, hospitalization due to PAH, or death (no patients died during this study).1
Figure adapted with permission from Rubenfire M, et al. Chest. 2007.
93% of patients (13 of 14) successfully transitioned from epoprostenol IV to SC Remodulin1,2
Transitioning from Flolan to IV Remodulin3
- In a 12-week, multicenter, open-label, investigator-initiated trial, 31 patients receiving optimal doses of conventional IV PAH therapies, as well as a stable dose of Flolan for ≥1 month were transitioned to IV Remodulin
- 6MWD was maintained in patients changing from Flolan to IV Remodulin (438 m vs 439 m, respectively)
- Borg dyspnea scores: no significant change
Transition from Flolan protocol
Transition from Flolan to Remodulin is accomplished by initiating and increasing the infusion of Remodulin (at a recommended dose of 10% of the current Flolan dose). The Remodulin dose should be increased as the Flolan dose is simultaneously decreased.1
Monitor your patients in a hospital to measure their response to Remodulin, including observing their vital signs, potential adverse reactions, and disease progression symptoms.1
6MWD=6-minute walk distance; IV=intravenous; PAH=pulmonary arterial hypertension; SC=subcutaneous.
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.
