Classification of Fibrinolytic Agents based on their Target of Action
Based on the Target of Action. Fibrinolytic Drugs are classified into 3 generations-
1st Generation: Acts by Fibrinolysis + Fibrinogenolytic action (Non-selective)
- Site of Action: Free Plasminogen and Fibrin found in Plasminogen (Less Specific).
- Examples: Streptokinase, Urokinase
- Mode of Action:
- Binds to Free Plasminogen: Depletes free fibrinogen (Fibrinogenolysis) Bleeding Complication
- Binds to Fibrin bound Plasminogen: Fibrinolysis (Less Specific)
2nd Generation: Acts by mostly on Fibrinolysis (75 % Selective)
- Site of Action: Fibrin found in Plasminogen.
- Examples: Alteplase
- Mode of Action:
- Binds with Fibrin found in plasminogen (75%): Fibrinolysis
- More Fibrin Specific (75%)
3rd Generation: Acts selectively on Fibrinolysis (Selective)
- Site of Action: Fibrin bound Plasminogen.
- Examples: Reteplase, Monteplase
- Mode of Action:
- Binds selectively with Fibrin Bound Plasminogen
- Activation of Plasmin
- Fibrinolysis
Mention the names of the drugs that acts as P2Y12 receptor inhibitors
Clopidogrel, the first P2Y12 inhibitor, was the standard for DAPT until newer options became available.
