How does this medication work? What will it do for me?
Tirofiban belongs to the family of medications known as platelet aggregation inhibitors. Platelets are a component of the blood that is very important to blood clotting. Heart attacks are caused by blood clots that block the required flow of blood to the heart.
Tirofiban works by preventing platelets from forming blood clots. It is used in combination with heparin (a medication also used to prevent blood clots) and acetylsalicylic acid (ASA) to prevent additional heart attacks or unstable angina (chest pain that gets worse with time and puts a person at risk for heart attack) for people who have recently experienced such events.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles.

The dose of medication required is based on a person’s condition and body weight.
