Ticagrelol Versus Aspirin in Ischemic Stroke

Status Completed

Clinical Trial Summary

There is a debate whether ticagrelor is superior to aspirin in treating patients with ischemic stroke or not, most of the studies examine the effect of both drugs within 24 hours of acute stroke some find that there is no difference between ticagrelor and aspirin, others find that ticagrelor is superior to aspirin. At this study the investigators aim at evaluating the role of loading ticagrelor received within 9 hours of acute ischemic stroke in improving neurological outcome of stroke. And evaluating the risk of hemorrhagic and non- hemorrhagic complications associated with the use of ticagrelor180 ml oral loading dose within 9 hours acute ischemic stroke

Clinical Trial Description

ticagrelor is acyclo-pentyltriazolo-pyrimidine antiplatelet drug that inhibits the P2Y12which is a subtype of adenosine diphosphate (ADP)receptor. It is a potent , direct-acting oral agent and it is reversibly binding P2Y12 receptors antagonist unlike the irreversible agents as clopidogrel, prasugrel, ticlopidine. In 2011, the U.S. Food and Drug Administration (FDA) approved the blood-thinning drug (ticagrelor) to treat acute coronary syndromes, and in 2015, it approved it as long-term treatment in patient with history of heart attack. In 2018, the American Heart Association ( AHA ) and American stroke Association (ASA) Guidelines for the Early Management of Patients with Acute Ischemic Stroke stated that, ticagrelor was not found to be superior to aspirin. However, because there were no significant safety differences, ticagrelor may be a reasonable alternative in stroke patients who have a contraindication to aspirin. Aspirin overall reduces the risk of major vascular events by 13% Moreover, the risk of hemorrhagic events limits the use of aspirin in this setting, so the investigators aim at examining the hemorrhagic risks associated with use of loading Ticagrelor 180 ml within 9 hours of 1st ever acute ischemic stroke and compare the neurological outcomes in two groups of patients with 1st ever acute ischemic stroke receiving within 9 hours either Aspirin(300 mg (4 tablets of 75 mg) as a single loading oral dose, and will then be commenced on 300 mg Aspirin daily for 2 weeks then 75 mg daily after that for 3 months and the other received 180 mg ticagrelor (2 tablets of 90 mg) as a single loading oral dose, and continue on 180 mg ticagrelor (1 tablet of 90 mg every 12 hours) for 3 months. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
