Recombinate: Công dụng, liều dùng, tác dụng phụ, bảo quản và cách dùng

Recombinate is an FDA-approved intravenous (IV) factor VIII replacement therapy used to control bleeding episodes in people with bệnh máu khó đông A. It is also used to manage bleeding before, during, and after surgery in people with hemophilia A. 

Recombinate Introduction and Uses

Recombinate is a brand-name prescription product. The active ingredient is a lab-made form of factor VIII, also known as antihemophilic factor, a natural clotting protein found in blood. Recombinate does not contain any human blood products. 

Recombinate belongs to the drug class called coagulation factors or hemostatics. 

A healthcare provider may prescribe Recombinate for people with hemophilia A to control bleeding episodes or manage bleeding around surgery. 

Recombinate is not indicated for the treatment of bệnh von Willebrand (VWD).  

Availability note: Takeda has announced the global discontinuation of Recombinate and previously stated that it intended to continue supplying the medication to existing patients until inventory was depleted or expired in mid-2026. Patients currently using Recombinate should speak with their healthcare provider about product availability and whether a transition to another factor VIII therapy is needed. 

Recombinate Mechanism of Action

Người mắc bệnh máu khó đông loại A có yếu tố đông máu VIII bị thiếu hụt hoặc rối loạn chức năng. Yếu tố VIII cần thiết cho quá trình đông máu, và sự thiếu hụt có thể gây chảy máu kéo dài hoặc tự phát vào khớp, cơ hoặc các cơ quan nội tạng.

Recombinate works by temporarily replacing the missing clotting factor VIII in the blood, helping the blood form clots and control bleeding.

Recombinate Dosing

Bác sĩ điều trị sẽ tính toán liều lượng dựa trên trọng lượng cơ thể, mức tăng hoạt tính yếu tố VIII mong muốn, đáp ứng lâm sàng và nhu cầu điều trị của bạn. Luôn luôn sử dụng liều lượng được kê đơn riêng cho bạn.

Recombinate comes as an off-white to faint yellow powder in single-dose vials. It is available in nominal dosage strengths of approximately 250, 500, 1,000, 1,500, and 2,000 International Units (IU) per vial. The powder must be mixed with an appropriate volume of Sterile Water for Injection before intravenous (IV) infusion. Your provider will use a vial size that is appropriate for your calculated dose.

Dosing for Treatment of Bleeding Episodes 

Mild bleeding: The dose is individualized to achieve a post-infusion factor VIII activity level of approximately 20% to 40% of normal. It is administered every 12 to 24 hours for 1 to 3 days until healing is achieved or the bleeding is adequately resolved. 

Chảy máu mức độ vừa phải: The dose is individualized to achieve a post-infusion factor VIII activity level of approximately 30% to 60% of normal. Treatment may be repeated every 12 to 24 hours for 3 days or more until pain or disability is resolved. 

chảy máu đe dọa tính mạng: The dose is individualized to achieve a post-infusion factor VIII activity level of approximately 60% to 100% of normal. Treatment may be repeated every 8 to 24 hours until the threat no longer exists. 

Dosing for Surgery

Phẫu thuật nhỏ: The dose is individualized to achieve a post-infusion factor VIII activity level of approximately 60% to 80% of normal. According to the prescribing information, a single infusion plus oral antifibrinolytic therapy within 1 hour is sufficient in approximately 70% of cases. 

Phẫu thuật lớn: The dose is individualized to achieve a factor VIII activity level of 80% to 100% of normal (pre- and post-operative). Treatment may be repeated every 8 to 24 hours. 

Recombinate Side Effects

Tác dụng phụ thường gặp

In clinical studies, the most commonly reported side effects included:

• Ớn lạnh
• Xả nước
• Phát ban
• Chảy máu mũi

Other side effects reported during clinical trials included nausea, fatigue, fever, dizziness, itching, pain in an extremity, and low blood pressure.

Serious risks include severe allergic reactions and the development of factor VIII inhibitors. Contact your healthcare provider right away if bleeding does not stop after using Recombinate, as this may be a sign that the medication is not working as expected. Seek immediate medical care if you develop symptoms of a severe allergic reaction. 

Recombinate Important Information and Warnings

Never attempt to inject this medication on your own unless you know how to safely administer it. Carefully follow your healthcare provider’s instructions about the dose and schedule for administering Recombinate. 

Phản ứng dị ứng nghiêm trọng

Recombinate may cause serious allergic reactions, including phản vệ. Anaphylaxis is a potentially life-threatening allergic reaction that can cause difficulty breathing, swelling, chest tightness, wheezing, or low blood pressure.

Stop using Recombinate and seek immediate medical care if you develop symptoms of a severe allergic reaction, such as:

• Phát ban và ngứa
• Khàn giọng
• Khó thở
• Khó nuốt
• Sưng tay, mặt hoặc miệng
• tức ngực
• Huyết áp thấp

Sản xuất chất ức chế (kháng thể)

In some cases, your body can develop proteins called inhibitors (antibodies) against factor VIII, which can prevent Recombinate from working well to treat or prevent bleeding. Inhibitor development is an important concern, particularly in previously untreated patients. 

Your healthcare provider will likely order tests to measure factor VIII inhibitors in your blood if:

• Factor VIII level doesn’t increase as expected after starting treatment
• Bleeding doesn’t stop with an appropriate dose

Before Taking Recombinate

Before using Recombinate, tell your healthcare provider if you:

• Are allergic to Recombinate, any of its ingredients, or mouse, hamster, or bovine proteins
• Have or have previously developed factor VIII inhibitors
• Đang mang thai hoặc đang có kế hoạch mang thai
• Đang cho con bú hoặc có kế hoạch cho con bú 

Don’t use Recombinate if you have a known hypersensitivity to Recombinate, any of its ingredients, or mouse, hamster, or bovine proteins.
