Indications for FLOLAN:

Pulmonary arterial hypertension (PAH) (WHO Group I) in patients with NYHA Class III or IV symptoms, to improve exercise ability.


Give by continuous chronic IV infusion through a central venous catheter. Initially 2ng/kg/min; increase in increments of 1–2ng/kg/min at ≥15min intervals based on response. Decrease dose gradually in 2ng/kg/min decrements at ≥15min intervals until dose-limiting effects resolve.


Not established.


Heart failure due to reduced left ventricular ejection fraction.


Avoid abrupt withdrawal or large dose reductions (may cause rebound pulmonary hypertension). Discontinue if pulmonary edema occurs; do not restart. Increased risk for hemorrhagic complications. Monitor BP and symptoms of vasodilation during initiation and after dose changes. Pregnancy. Nursing mothers.
