Aprotinin

Introduction

Aprotinin is a protease inhibitor used primarily during complex surgeries to reduce bleeding and the need for blood transfusions. It works by slowing the breakdown of blood clots, helping maintain clot stability throughout the procedure. Aprotinin has been commonly administered during heart surgeries, especially those involving cardiopulmonary bypass. Its use is tightly controlled in clinical settings due to associated safety concerns but remains vital in reducing surgical blood loss and improving patient outcomes during major operations.

Uses of Aprotinin

• Reduces bleeding during open-heart or bypass surgeries
• Helps stabilize blood clots during major operations
• Used to decrease the need for blood transfusions in surgery

How Aprotinin works

Aprotinin works by inhibiting several enzymes involved in the breakdown of blood clots (fibrinolysis). It preserves clot integrity during surgeries by blocking enzymes such as trypsin and plasmin. This helps reduce excessive bleeding and the need for transfusions.

Benefits of Aprotinin

• Minimizes surgical blood loss
• Reduces reliance on blood transfusions
• Improves surgical outcomes in high-risk procedures
• Shortens operation and recovery time by stabilizing clots

How to take Aprotinin

Aprotinin is administered by a healthcare professional through an intravenous (IV) infusion during surgery. Dosage depends on the type and length of surgery, patient’s condition, and other medical factors. It must be given in a controlled hospital setting under medical supervision.

Type of Dosage Available

• Injection (IV Infusion)

Side effects of Aprotinin

• Nausea and vomiting
• Fever or chills
• Allergic reactions (rash, itching, swelling)
• Kidney dysfunction or failure (in rare cases)
• Low blood pressure
• Breathing difficulty

Safety advice

• Use only under hospital supervision
• Not recommended in patients with a history of allergic reactions to Aprotinin
• Inform the doctor of any kidney problems
• Monitor renal function closely during and after use
• Discuss all medications you’re taking with your doctor
