Indications
Tirofiban Hydrochloride is used to lower the rate of thrombotic cardiovascular events in patients with non-ST elevation acute coronary syndrome (NSTE-ACS). These events are counted together as one combined endpoint: death, myocardial infarction, or refractory ischemia/repeat cardiac procedure.
⚠️ Always consult a registered physician before taking any medicine.
Pharmacology
Tirofiban is a reversible antagonist of fibrinogen binding to the GP IIb/IIIa receptor. This is the main receptor on the platelet surface that takes part in platelet aggregation. When Tirofiban is given intravenously, it inhibits ex vivo platelet aggregation, and the effect depends on the dose and the concentration.
With the PRISM-PLUS regimen, the patient gets 0.4 mcg/kg/min over 30 minutes, followed by a maintenance infusion of 0.1 mcg/kg/min. Inhibition of platelet aggregation of >90% is reached by the end of the 30-minute infusion. With the recommended regimen of 25 mcg/kg followed by a maintenance infusion of 0.15 mcg/kg/min, >90% inhibition is reached within 10 minutes.
The inhibition of platelet aggregation is reversible once the Tirofiban infusion is stopped.
Pregnancy & Breastfeeding
Tirofiban is Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women. In pregnant rats and rabbits, tirofiban has been shown to cross the placenta. Tirofiban HCl was given intravenously at doses up to 5 mg/kg/day (about 5 times the maximum recommended daily human dose for rats and 13 times for rabbits, compared on a body surface area basis), and no harm to the fetus was found.
Nursing mothers: it is not known whether tirofiban is excreted in human milk. Significant levels of tirofiban were present in rat milk, though. Many drugs pass into human milk, and there is a chance of adverse effects on the nursing infant, so nursing should be stopped or AGGRASTAT should be stopped.
