Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

During clinical trials, adverse events were classified as follows: (1) adverse events during dose initiation and escalation, (2) adverse events during chronic dosing, and (3) adverse events associated with the drug delivery system.

Adverse Events During Dose Initiation And Escalation

During early clinical trials, epoprostenol was increased in 2-ng/kg/min increments until the patients developed symptomatic intolerance. The most common adverse events and the adverse events that limited further increases in dose were generally related to vasodilation, the major pharmacologic effect of epoprostenol. The most common dose-limiting adverse events (occurring in >1% of patients) were nausea, vomiting, headache, hypotension, and flushing, but also include chest pain, anxiety, dizziness, bradycardia, dyspnea, abdominal pain, musculoskeletal pain, and tachycardia. Table 8 lists the adverse events reported during dose initiation and escalation in decreasing order of frequency.

Table 8: Adverse Events during Dose Initiation and Escalation

Adverse Events Occurring in ≥1% of Patients Epoprostenol
Flushing 58%
Headache 49%
Nausea/vomiting 32%
Hypotension 16%
Anxiety, nervousness, agitation 11%
Chest pain 11%
Dizziness 8%
Bradycardia 5%
Abdominal pain 5%
Musculoskeletal pain 3%
Dyspnea 2%
Back pain 2%
Sweating 1%
Dyspepsia 1%
Hypesthesia/paresthesia 1%
Tachycardia 1%

Adverse Events During Chronic Administration

Interpretation of adverse events is complicated by the clinical features of PAH, which are similar to some of the pharmacologic effects of epoprostenol (e.g., dizziness, syncope). Adverse events which may be related to the underlying disease include dyspnea, fatigue, chest pain, edema, hypoxia, right ventricular failure, and pallor. Several adverse events, on the other hand, can clearly be attributed to epoprostenol. These include hypotension, bradycardia, tachycardia, pulmonary edema, bleeding at various sites, thrombocytopenia, headache, abdominal pain, pain (unspecified), sweating, rash, arthralgia, jaw pain, flushing, diarrhea, nausea and vomiting, flu-like symptoms, anxiety/nervousness, and agitation. In addition, chest pain, fatigue, and pallor have been reported during epoprostenol therapy, and a role for the drug in these events cannot be excluded.

Adverse Events During Chronic Administration For Idiopathic Or Heritable PAH

In an effort to separate the adverse effects of the drug from the adverse effects of the underlying disease, Table 9 lists adverse events that occurred at a rate at least 10% greater on epoprostenol than on conventional therapy in controlled trials for idiopathic or heritable PAH.

Table 9: Adverse Events Regardless of Attribution Occurring in Patients with Idiopathic or Heritable PAH with ≥10% Difference between Epoprostenol and Conventional Therapy Alone

Adverse Event Epoprostenol
Conventional Therapy
Occurrence More Common With Epoprostenol
Chills/fever/sepsis/flu-like symptoms 25% 11%
Tachycardia 35% 24%
Flushing 42% 2%
Diarrhea 37% 6%
Nausea/vomiting 67% 48%
Jaw pain 54% 0%
Myalgia 44% 31%
Nonspecific musculoskeletal pain 35% 15%
Anxiety/nervousness/tremor 21% 9%
Dizziness 83% 70%
Headache 83% 33%
Hypesthesia, hyperesthesia, paresthesia 12% 2%

Thrombocytopenia has been reported during uncontrolled clinical trials in patients receiving epoprostenol.

Adverse Events During Chronic Administration For PAH/SSD

In an effort to separate the adverse effects of the drug from the adverse effects of the underlying disease, Table 10 lists adverse events that occurred at a rate at least 10% greater on epoprostenol in the controlled trial.

Table 10: Adverse Events Regardless of Attribution Occurring in Patients with PAH/SSD With ≥10% Difference Between Epoprostenol and Conventional Therapy Alone

Adverse Event Epoprostenol
Conventional Therapy
Flushing 23% 0%
Hypotension 13% 0%
Anorexia 66% 47%
Nausea/vomiting 41% 16%
Diarrhea 50% 5%
Jaw pain 75% 0%
Pain/neck pain/arthralgia 84% 65%
Headache 46% 5%
Skin and Appendages
Skin ulcer 39% 24%
Eczema/rash/urticaria 25% 4%

Although the relationship to epoprostenol administration has not been established, pulmonary embolism has been reported in several patients taking epoprostenol and there have been reports of hepatic failure.

Adverse Events Attributable To The Drug Delivery System

Chronic infusions of epoprostenol are delivered using a small, portable infusion pump through an indwelling central venous catheter. During controlled PAH trials of up to 12 weeks' duration, the local infection rate was about 18%, and the rate for pain was about 11%. During long-term follow-up, sepsis was reported at a rate of 0.3 infections/patient per year in patients treated with epoprostenol. This rate was higher than reported in patients using chronic indwelling central venous catheters to administer parenteral nutrition, but lower than reported in oncology patients using these catheters. Malfunctions in the delivery system resulting in an inadvertent bolus of or a reduction in epoprostenol were associated with symptoms related to excess or insufficient epoprostenol, respectively

Postmarketing Experience

In addition to adverse reactions reported from clinical trials, the following events have been identified during post-approval use of epoprostenol. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency of reporting, or potential causal connection to epoprostenol.

Blood and Lymphatic: Anemia, hypersplenism, pancytopenia, splenomegaly.

Cardiac: High output cardiac failure (consider dose reduction) [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS, and WARNINGS AND PRECAUTIONS].

Endocrine and Metabolic: Hyperthyroidism


Additional reductions in blood pressure may occur when VELETRI is administered with diuretics, antihypertensive agents, or other vasodilators. When other antiplatelet agents or anticoagulants are used concomitantly, there is the potential for VELETRI to increase the risk of bleeding. However, patients receiving infusions of epoprostenol in clinical trials were maintained on anticoagulants without evidence of increased bleeding. In clinical trials, epoprostenol was used with digoxin, diuretics, anticoagulants, oral vasodilators, and supplemental oxygen.

In a pharmacokinetic substudy in patients with congestive heart failure receiving furosemide or digoxin in whom therapy with epoprostenol was initiated, apparent oral clearance values for furosemide (n=23) and digoxin (n=30) were decreased by 13% and 15%, respectively, on the second day of therapy and had returned to baseline values by day 87. The change in furosemide clearance value is not likely to be clinically significant. However, patients on digoxin may show elevations of digoxin concentrations after initiation of therapy with epoprostenol, which may be clinically significant in patients prone to digoxin toxicity.
