  Thrombolytic drug - Wikipedia, the free encyclopedia
Thrombolytic drugs are used in medicine to dissolve blood clots in a procedure termed thrombolysis.
A less frequent use is to clear blocked catheters that are used in long-term medical therapy.
It should be noted that thrombolytic therapy in hemorrhagic strokes is contraindicated, as its use in that situation would prolong bleeding and hasten the demise of the patient.

 Special Procedures, Thrombolytic Therapy
At the time of the consensus conference, thrombolytic therapy meant administration of large systemic intravenous doses of thrombolytic enzyme, and it was associated with a four-fold increase in major and minor bleeding (39%) compared with heparin alone (10%).
It is probably that because of these two factors, not enough patients have received thrombolytic therapy to be able to answer the question of whether rapid restoration of venous function with thrombolytic therapy prevents the long-term complications associated with anticoagulant therapy.
This protocol is similar to thrombolytic regimens provided by university centers in that it involves catheterization of the thrombosed vein in order to inject the thrombolytic enzyme directly into the thrombus.

 Thrombolytic Therapy Underused In Elderly Patients With Heart Attack
Past clinical trials among nearly 60,000 patients have shown that thrombolytic therapy is associated with an 18 percent reduction in the odds of dying among those with suspected heart attack.
In addition: "Physicians are less likely to use thrombolytic therapy in eligible patients with characteristics associated with an increased risk of bleeding, lower-risk infarction, less certain diagnosis, less certain efficacy, or altered mental state," the researchers write.
Thrombolytic therapy is most effective when fewer than six hours has elapsed from the onset of symptoms.

 s000417b - Angioplasty vs. Thrombolytic Therapy - Trials
Thrombolytic therapy was not an independent predictor of short-term: mortality (odds ratio 0.67, 95% CI 0.37-1.20).
The success of thrombolytic therapy for acute myocardial infarction is limited by bleeding: complications, the impossibility of reperfusing all occluded coronary arteries, recurrent myocardial ischemia, and the: relatively small number of patients who are appropriate candidates for this therapy.
Despite the widespread use of intravenous thrombolytic therapy and of immediate percutaneous: transluminal coronary angioplasty for the treatment of acute myocardial infarction, randomized comparisons of the: two approaches to reperfusion are lacking.

 Thrombolytic Therapy
Administration of thrombolytics in the emergency department, either by the emergency department physician or by the patient’s private physician, is now the standard of care for acute myocardial infarction.
Because of this risk, thrombolytics are contraindicated in patients with a history of stroke, brain tumor or AV malformation, or recent CNS surgery.
Thrombolytics may be used for other situations, such as clotted dialysis fistula, pulmonary embolism, or DVT when appropriate.

 Thrombolytic agent definition - Medical Dictionary definitions of popular medical terms
Thrombolytic agent: A drug that is able to dissolve a clot (thrombus) and reopen an artery or vein.
Thrombolytic agents may be used to treat a heart attack, stroke, deep vein thrombosis (clot in a deep leg vein), pulmonary embolism, and occlusion of a peripheral artery or indwelling catheter.
All thrombolytic agents are serine proteases (they digest protein) and convert plasminogen to plasmin which breaks down the fibrinogen and fibrin and dissolves the clot.
