What Is Tirofiban and How Does It Work?

To understand how tiroifiban helps, let us look at how your blood works every day. Your blood contains tiny cell fragments called platelets. Their main job is to stick together when you get a cut to stop bleeding and help you heal.

However, problems can happen inside the blood vessels that supply blood to your heart, known as coronary arteries. Sometimes, platelets stick together when they should not, forming dangerous blood clots. If a clot blocks your blood vessel completely, it stops blood flow and causes a heart attack.

Tiroifiban injection stops these platelets from sticking together and forming clots. During a heart attack or severe chest pain, known as unstable angina, this medicine stops the condition from getting worse. Doctors also use it during procedures like angioplasty to keep your blood vessels open and prevent complications.
