This page contains brief details about the drug , it's indication, dosage & administaration, mechanism of action, related brands with strength, warnings and common side effects.

Background and Date of Approval

Tirofiban hydrochloride (HCl) was initially approved by the U.S. Food and Drug Administration (FDA) on June 3, 1998.

Mechanism of Action of undefined

Tirofiban hydrochloride (HCl)  works by inhibiting the glycoprotein IIb/IIIa receptor on the surface of platelets. This receptor plays a crucial role in platelet aggregation and clot formation. By blocking this receptor, tirofiban helps prevent the formation of blood clots.

Uses of undefined

Tirofiban hydrochloride (HCl) is an antiplatelet medication with multiple clinical applications. Its primary uses include managing acute coronary syndromes (ACS), encompassing unstable angina and non-ST-segment elevation myocardial infarction (NSTEMI), by reducing the risk of coronary artery clot formation. During percutaneous coronary interventions (PCI) like angioplasty and stent placement, it prevents platelet aggregation and clot formation at the intervention site. Additionally, it is occasionally considered for managing thrombocytopenia, investigated for ischemic stroke cases, used in some coronary artery bypass grafting (CABG) procedures to minimize graft occlusion risk, and employed adjunctively in high-risk patients prone to clot formation.

undefined Drug administaration and Dosage available

Tirofiban hydrochloride (HCl) is typically administered intravenously (IV), giving it directly into a vein. It is usually administered in a healthcare setting, such as a hospital, where medical professionals can closely monitor the patient.

Warnings, Precautions and Side Effects of undefined


Tirofiban hydrochloride (HCl) significantly increases the risk of bleeding, ranging from minor bleeding at the injection site to more severe events, including gastrointestinal bleeding or intracranial hemorrhage. Anaphylactic reactions are rare but can be life-threatening. It can cause a decrease in platelet counts (thrombocytopenia). Severe thrombocytopenia can increase the risk of bleeding.


Tirofiban hydrochloride (HCl) should be used cautiously in patients with a history of bleeding disorders, recent surgery, or trauma. Close monitoring of bleeding parameters, such as platelet counts and signs of bleeding, is essential during treatment. If any signs of an allergic reaction occur, treatment should be discontinued, and immediate medical attention should be sought. Platelet counts should be monitored regularly during treatment, and the medication should be discontinued if significant thrombocytopenia occurs.

Side Effects

Tirofiban hydrochloride (HCl) can cause various side effects, ranging from common to serious. Common side effects may include bleeding at the injection site, nausea, headache, fever, and mild chest discomfort. On the other hand, serious side effects, which require immediate medical attention, encompass severe bleeding events, thrombocytopenia (a decrease in platelet count), and allergic reactions with symptoms like rash, swelling, difficulty breathing, and low blood pressure. While less common, tirofiban may lead to back pain or chest pain. 

Word Of Advice

Tirofiban hydrochloride (HCl) should be used cautiously due to its potential to increase bleeding risk. Patients with bleeding disorders, recent surgery, or a tendency to bleed easily should be vigilant. Monitoring for allergic reactions, low blood pressure, and platelet counts is essential, and kidney and liver function should be checked. Medication interactions, especially with blood thinners, require careful management. Pregnant or breastfeeding individuals should consult their healthcare provider before using this medication. Platelet function and cardiac monitoring may be necessary during treatment. Knowing the location of the nearest emergency medical facility is important, and proper IV administration is crucial.
