DailyMed – FLOLAN- epoprostenol sodium injection, powder, lyophilized, for solution DILUENT- water solution

2.3 Administration

Initiate FLOLAN in a setting with adequate personnel and equipment for physiologic monitoring and emergency care.

Inspect parenteral drug products for particulate matter and discoloration prior to administration whenever solution and container permit. If either particulate matter or discoloration is noted, do not use.

Administer continuous chronic infusion of FLOLAN through a central venous catheter. Temporary peripheral intravenous infusion may be used until central access is established. Do not administer bolus injections of FLOLAN.

The ambulatory infusion pump used to administer FLOLAN should: (1) be small and lightweight, (2) be able to adjust infusion rates in 2‑ng/kg/min increments, (3) have occlusion, end-of-infusion, and low-battery alarms, (4) be accurate to ± 6% of the programmed rate, and (5) be positive-pressure‑driven (continuous or pulsatile) with intervals between pulses not exceeding 3 minutes at infusion rates used to deliver FLOLAN. The reservoir should be made of polyvinyl chloride, polypropylene, or glass. Use a 60-inch microbore non-di-(2-ethylhexyl)phthalate (DEHP) extension set with proximal antisyphon valve, low-priming volume (0.9 mL), and in-line 0.22-micron filter.

Preparation and administration materials containing polyethylene terephthalate (PET) or polyethylene terephthalate glycol (PETG) may become damaged when used with FLOLAN prepared with pH 12 STERILE DILUENT for FLOLAN and therefore must not be used.

Consult the manufacturer of the sets to confirm that they are considered compatible with highly alkaline solutions, such as FLOLAN prepared with pH 12 STERILE DILUENT for FLOLAN.

To avoid interruptions in drug delivery, the patient should have access to a backup infusion pump and intravenous infusion sets.

Do not administer or dilute reconstituted solutions of FLOLAN with other parenteral solutions or medications. Consider a multi‑lumen catheter if other intravenous therapies are routinely administered.

Select a concentration for the solution of FLOLAN that is compatible with the infusion pump being used with respect to minimum and maximum flow rates, reservoir capacity, and the infusion pump criteria listed above. When administered chronically, prepare FLOLAN in a drug delivery reservoir appropriate for the infusion pump with a total reservoir volume of at least 100 mL, using 2 vials of pH 12 STERILE DILUENT for FLOLAN.

Generally, 3,000 ng/mL and 10,000 ng/mL are satisfactory concentrations to deliver between 2 to 16 ng/kg/min in adults. Higher infusion rates, and therefore, more concentrated solutions may be necessary with long‑term administration of FLOLAN.

Infusion rates may be calculated using the following formula:
