Nepofer(Ferric Pyrophosphate Citrate)
Therapeutic Group: Parenteral Iron Preparation
Presentation
Nepofer: Each 5 ml solution contains Ferric Pyrophosphate Citrate INN equivalent to 27.2 mg elemental Iron.
Description
Ferric Pyrophosphate Citrate solution is a mixed-ligand iron complex in which iron (III) is bound to pyrophosphate and citrate. Ferric Pyrophosphate Citrate solution is a clear, slightly yellow-green color sterile solution containing 27.2 mg iron (III) per 5 mL. Each Nepofer ampoule contains iron (7.5-9.0% w/w), citrate (15-22% w/w), pyrophosphate (15-22% w/w), phosphate (< 2% w/w), sodium (18-25% w/w) and sulfate (20-35%). One ampoule is added to 2.5 gallons (9.46 L) of bicarbonate concentrate.
Indications
Ferric Pyrophosphate Citrate is indicated for the replacement of iron to maintain hemoglobin in adult patients with hemodialysis-dependent chronic kidney disease (HDD-CKD).
Dosage & Administration
Inspect Nepofer ampoule for signs of precipitation prior to mixing with the bicarbonate concentrate. Ferric Pyrophosphate Citrate should only be added to the bicarbonate concentrate and should not be added to acid concentrate mixtures. Add Ferric Pyrophosphate Citrate to bicarbonate concentrate used for generation of hemodialysate. The final concentration of Nepofer iron (III) in the final hemodialysate is 2 micromolar (110 mcg/L). Multiple ampoules can be added to the master bicarbonate mix at each center at a ratio of one (1) ampoule to each 2.5 gallons of bicarbonate concentrate.
Administer Ferric Pyrophosphate Citrate to patients at each dialysis procedure for as long as patients are receiving maintenance hemodialysis therapy for CKD.
Hemodialysis solutions should be used within 24 hours of the preparation of the Ferric Pyrophosphate Citrate /bicarbonate concentrate mixture.
Side Effects
The most common side effects are headache, peripheral edema, asthenia, AV fistula thrombosis, urinary tract infection, AV fistula site hemorrhage, pyrexia, fatigue, hypotension, muscle spasms, pain in extremity, back pain, and dyspnea.
Precautions
Hypersensitivity Reactions
Anaphylactic-type reactions, shock, hypotension, loss of consciousness and collapse can occur. Monitor patients for signs and symptoms of hypersensitivity during and after hemodialysis until he/she is clinically stable. Personnel and therapies should be immediately available for the treatment of serious hypersensitivity reactions.
Iron laboratory testing
Iron status should be determined on pre-dialysis blood samples. Post dialysis serum iron parameters may overestimate serum iron and transferrin saturation.
