Early use of tirofiban after thrombolysis for acute ischemic stroke

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the efficacy and safety of administering tirofiban, a glycoprotein IIb/IIIa receptor inhibitor, shortly after intravenous thrombolysis (IVT) in patients with acute ischemic stroke. The trial aims to determine if early tirofiban treatment can improve functional outcomes for patients who have undergone IVT, as previous studies with smaller sample sizes suggested potential benefits. Participants will be monitored for both efficacy and safety following the administration of tirofiban or a placebo within six hours after IVT.
