What drugs are used in thrombolytic therapy?
The most commonly used clot-busting drugs — also known as thrombolytic agents — include: Eminase ( anistreplase ) Retavase ( reteplase ) Streptase ( streptokinase , kabikinase ) t-PA (class of drugs that includes Activase ) TNKase ( tenecteplase ) Abbokinase , Kinlytic (rokinase)
What is a contraindication for thrombolytic therapy?
Relative contraindications (not absolute) to fibrinolytic therapy include: Uncontrolled hypertension (BP > 180/110), either currently or in the past. Intracranial abnormality not listed as absolute contraindication (i.e. benign intracranial tumor) Ischemic stroke more than 3 months prior.
What are the side effects of thrombolytic therapy?
Besides risk of serious internal bleeding , other possible risks include: Bruising or bleeding at the access site. Damage to the blood vessel. Migration of the blood clot to another part of vascular system. Kidney damage in patients with diabetes or other pre-existing kidney disease.
Is aspirin a thrombolytic?
In the last 50 years, aspirin has been shown to have remarkable antithrombotic benefits. Aspirin’s antithrombotic effect is mediated by inhibition of blood platelets. The drug blocks a platelet enzyme, cyclo-oxygenase, by acetylating the enzyme’s active site.
Is Heparin a thrombolytic drug?
Apart from streptokinase, all thrombolytic drugs are administered together with heparin (unfractionated or low molecular weight heparin ), usually for 24 to 48 hours. Thrombolysis is usually intravenous.
How long does it take for thrombolytic therapy to work?
To be effective, the therapy needs to be initiated as soon as possible, before permanent damage has occurred. The length of a treatment session varies depending on the underlying cause. A session can take from 60 minutes (typical for a heart attack ) to 48 hours (often the case for deep vein thrombosis , or DVT ).
Who is not a candidate for thrombolytic therapy?
Thrombolytic therapy is contraindicated in patients with known pregnancy, active internal bleeding, uncontrolled hypertension, aortic dissection, intracranial neoplasm or a history of hemorrhagic stroke. Heparin should be administered with both alteplase and streptokinase.
What are the 8 DS of stroke care?

Who Cannot receive thrombolytic?
Thrombolytic therapy cannot be recommended for persons excluded from the NINDS Study6 for one of the following reasons: (1) current use of oral anticoagulants or a prothrombin time greater than 15 seconds (International Normalized Ratio [INR] greater than 1.7); (2) use of heparin in the previous 48 hours and a
What is the most frequent adverse effect of thrombolytic therapy?
Adverse Effects Bleeding is the most frequent complication of thrombolytic therapy and can occur in puncture site or spontaneously anywhere inside the body.
How does thrombolytic therapy work?
Thrombolytics work by dissolving a major clot quickly. This helps restart blood flow to the heart and helps prevent damage to the heart muscle. Thrombolytics can stop a heart attack that would otherwise be larger or potentially deadly.
What is the antidote for thrombolytics?
Thrombolytic agents convert plasminogen to plasmin, which degrades fibrin at the site of thrombus formation. Antifibrinolytics such as aminocaproic acid (Amicar) seem to be a logical antidote to fibrinolytic therapy and have been proposed as an aggressive measure for limiting intracranial bleeding .
Can I take aspirin instead of blood thinners?
Taking aspirin to reduce blood -clotting is “as safe and just as effective as warfarin ”, The Daily Telegraph has today reported.
What drug is given during a heart attack?
