Antihemophilic Factor (Recombinant)
RECOMBINATE, Antihemophilic Factor (Recombinant) (rAHF) is a glycoprotein synthesized by a genetically engineered Chinese Hamster Ovary (CHO) cell line. In culture, the CHO cell line secretes recombinant antihemophilic factor (rAHF) into the cell culture medium. The rAHF is purified from the culture medium utilizing a series of chromatography columns. A key step in the purification process is an immunoaffinity chromatography methodology in which a purification matrix, prepared by immobilization of a monoclonal antibody directed to factor VIII, is utilized to selectively isolate the rAHF in the medium. The synthesized rAHF produced by the CHO cells has the same biological effects as Antihemophilic Factor (Human) [AHF (Human)]. Structurally the protein has a similar combination of heterogenous heavy and light chains as found in AHF (Human).
RECOMBINATE (antihemophilic factor recombinant) rAHF is formulated as a sterile, nonpyrogenic, off- white to faint yellow, lyophilized powder preparation of concentrated recombinant AHF for intravenous injection. RECOMBINATE (antihemophilic factor recombinant) rAHF is available in single-dose bottles which contain nominally 250, 500 and 1000 International Units per bottle. When reconstituted with the appropriate volume of diluent, the product contains the following stabilizers in maximum amounts: 12.5 mg/mL Albumin (Human), 0.20 mg/mL calcium, 1.5 mg/mL polyethylene glycol (3350), 180 mEq/L sodium, 55 mM histidine, 1.5 µg/AHF international Unit (IU) polysorbate-80. Von Willebrand Factor (vWF) is coexpressed with the Antihemophilic Factor (Recombinant) and helps to stabilize it. The final product contains not more than 2 ng vWF/IU rAHF which will not have any clinically relevant effect in patients with von Willebrand's disease. The product contains no preservative.
Manufacturing of RECOMBINATE (antihemophilic factor recombinant) rAHF is shared by Baxter Healthcare Corporation and Wyeth BioPharma. The recombinant Antihemophilic Factor Concentrate (For Further Manufacturing Use), is produced by Baxter Healthcare Corporation and Wyeth BioPharma (For Further Manufacturing Use) and subsequently formulated and packaged at Baxter Healthcare Corporation.
Each bottle of RECOMBINATE (antihemophilic factor recombinant) rAHF is labeled with the AHF activity expressed in IU per bottle. Biological potency is determined by an in vitroassay which is referenced to the World Health Organization (WHO) International Standard for Factor VIII:C Concentrate.
What are the possible side effects of recombinant antihemophilic factor?
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; feeling light-headed, fainting; swelling of your face, lips, tongue, or throat.
Stop using recombinant antihemophilic factor and call your doctor at once if you have a serious side effect such as:
- chest pain;
- easy bruising, increased bleeding episodes; or
- bleeding from a wound or where the medicine was injected.
Less serious side effects may include:
- sore throat, cough, runny nose;
- fever or...
What are the precautions when taking antihemophilic factor (recombinant) (Recombinate)?
Before using this medication, tell your doctor or pharmacist if you are allergic to any antihemophilic factor (factor VIII) products; or if you have any other allergies. Some brands may also contain animal proteins (such as mouse, hamster) or inactive ingredients (such as natural rubber/latex), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history.
Manufacturers of some brands of this medication recommend that you monitor your heartbeat during treatment. If your heart starts to beat faster, it is recommended that you give this medication more slowly or temporarily stop the infusion until your heart rate returns to normal. Consult your doctor for more...
