AprotininThird Party Manufacturing in India

Aprotinin works as a broad-spectrum, competitive serine protease inhibitor that blocks several key proteolytic enzymes. Its primary mechanism of action involves binding to and inactivating plasmin, the enzyme responsible for fibrinolysis (the breakdown of blood clots). By inhibiting plasmin, aprotinin helps preserve the structural integrity of fibrin within blood clots, thereby reducing clot breakdown and preventing excessive bleeding. Additionally, aprotinin inhibits plasma kallikrein, an enzyme that plays a central role in activating both the contact activation system of coagulation and the systemic inflammatory response.

Unlike synthetic antifibrinolytics like tranexamic acid, aprotinin is a natural monomeric polypeptide consisting of 58 amino acids. Its ability to inhibit kallikrein gives it an additional anti-inflammatory effect during major surgeries, such as those requiring cardiopulmonary bypass. It also helps preserve platelet function by protecting platelet membrane glycoproteins from proteolytic degradation. In its injectable formulation, it is administered intravenously to stabilize coagulation and reduce the need for blood transfusions during high-risk surgical procedures.

Aprotinin third party manufacturing in India is a specialized service for high-quality sterile injectables used to manage blood loss in critical surgical settings.

Therapeutic Uses

Aprotinin injection is prescribed for the treatment of:

• Reduction of Blood Loss in Cardiac Surgery: Indicated for prophylactic use to reduce perioperative blood loss and blood transfusion requirements in patients undergoing cardiopulmonary bypass during coronary artery bypass graft (CABG) surgery.
• Prevention of Systemic Inflammatory Response: Administered to high-risk patients to minimize contact activation and the inflammatory cascade triggered by extracorporeal circulation.
• Management of Severe Hemorrhage: Used off-label in specialized surgeries, such as orthotopic liver transplantation, where hyperfibrinolysis and heavy bleeding are anticipated.

Why Choose a Leading Aprotinin Manufacturer

Because aprotinin is a complex polypeptide, its production requires advanced protein purification techniques and rigorous quality control to ensure batch-to-batch consistency and the complete absence of immunogenic impurities. Sourcing from a WHO-GMP certified facility in India ensures that the sterile injectable formulation complies with international pharmacopoeial standards. Our manufacturing partners employ state-of-the-art aseptic processing lines, automated endotoxin testing, and temperature-controlled storage to maintain the stability and activity of this delicate protein.
