**Core Concept**
Tirofiban is a non-peptide, reversible antagonist of the glycoprotein IIb/IIIa receptor on platelets, which is critical for platelet aggregation and clot formation.

**Why the Correct Answer is Right**
Tirofiban works by selectively inhibiting the glycoprotein IIb/IIIa receptor, thereby preventing the binding of fibrinogen to the receptor and subsequent platelet aggregation. This results in reduced clot formation and decreased risk of thrombotic complications, such as myocardial infarction and stroke. Tirofiban is used in combination with heparin and aspirin for the management of acute coronary syndromes.

**Why Each Wrong Option is Incorrect**
**Option A:** Tirofiban is not a monoclonal antibody; it is a small molecule inhibitor of the glycoprotein IIb/IIIa receptor.
**Option C:** Tirofiban does not have anti-inflammatory properties; its primary mechanism is through inhibition of platelet aggregation.
**Option D:** Tirofiban is not an antianginal drug; it is used to prevent thrombotic complications in acute coronary syndromes.

**Clinical Pearl / High-Yield Fact**
Remember that glycoprotein IIb/IIIa inhibitors like tirofiban are primarily used in acute coronary syndromes, and their efficacy is most pronounced when used in combination with heparin and aspirin.
