Thrombolytic drugs are used to dissolve (lyse) blood clots (thrombi). Blood clots can occur in any vascular bed; however, when they occur in coronary, cerebral or pulmonary vessels, they can be immediately life-threatening - coronary thrombi are the cause of myocardial infarctions, cerebrovascular thrombi produce strokes, and pulmonary thromboembolic can lead to respiratory and cardiac failure. Therefore, it is important to rapidly diagnose and treat blood clots.
Thrombolytic drugs dissolve blood clots by activating plasminogen, which forms a cleaved product called plasmin. Plasmin is a proteolytic enzyme that is capable of breaking cross-links between fibrin molecules, which provide the structural integrity of blood clots. Because of these actions, thrombolytic drugs are also called "plasminogen activators" and "fibrinolytic drugs."
There are three major classes of fibrinolytic drugs: tissue plasminogen activator (tPA), streptokinase (SK), and urokinase (UK). While drugs in these three classes all have the ability to effectively dissolve blood clots, they differ in their detailed mechanisms in ways that alter their selectivity for fibrin clots.

What is the different between thrombolytic & anticoagulant?
The basic difference is that, Anticoagulants are those agent which avoid the clotting of blood but can't destroy existing clots...
And Thrombolytic agents lyse or destroy the clot by activating the plasminogen..
🙏
🙏🙏🙏🙏🙏🙏🙏
Sir what is the difference between anticoagulant and fibrinolytic
Good question. Anticoagulant drugs prevent blood from making clot but fibrinolytic drugs breck the fibrin which is present in already clotted blood. Means one act before clotting to reduce this and another act after clotting to dissolve it.
@@solutionpharmacythank you sir for clearing the concept
@@solutionpharmacy thnk you sir
Sir link nhi mil rha 😢
Sir, what is the difference between thrombolytics and anti-coagulants ?
Anticoagulant will prevent from being clot but thrombolytic will break thrombus once clotted
@@solutionpharmacy Thank you sir
Sir, difference between thrombolytics and anti-coagulant
Thrombolytuc will brek the throbmin when blood is already clotted. And anticoagulant will inhibit the cascade of reaction responsible for clotting (Before and after)
Sir anti coagulant, anti Platelet, anti thrombotic drugs me different kya hai?
Videos dekhiyega sab clear ho jayega
