Anti-Platelet Drugs

Anti-Platelet Drugs

Definition of Anti-Platelet Drugs Anti-Platelet Drugs agents inhibit platelet aggregation and activation, thereby preventing thrombus formation. Classes of Anti-Platelet Agents Aspirin (Acetylsalicylic Acid): Mechanism: Irreversibly inhibits cyclooxygenase-1 (COX-1), reducing thromboxane A2 synthesis, which decreases platelet aggregation. Use: Prevention of AMI, stroke, and in peripheral arterial disease. Side Effects: Gastrointestinal ulcers, bleeding, Reye’s syndrome in children. … Read more

Fibrinolytics

Fibrinolytics

Definition of Fibrinolytics: Fibrinolytics, also known as thrombolytics, are agents that dissolve blood clots by activating the fibrinolytic system. Mechanism of Action Activation of Plasminogen: Fibrinolytics convert plasminogen to plasmin, an enzyme that degrades fibrin clots. Cleavage of Fibrin: Plasmin breaks down fibrin into soluble degradation products, dissolving the clot. Common Fibrinolytic Agents Alteplase (tPA): … Read more

Anticoagulants

Anticoagulants

Definition of Anticoagulants: Anticoagulants inhibit various components of the coagulation cascade to prevent thrombus formation, used in conditions at risk for thrombosis. Heparin and Low Molecular Weight Heparins (LMWHs) Examples: Enoxaparin Mechanism: Heparin activates antithrombin III, which inactivates thrombin and factor Xa; LMWHs have more selective inhibition of factor Xa. Use: Deep vein thrombosis (DVT), … Read more

Coagulants

Coagulants

Definition of Coagulants: Coagulants are agents that promote clotting, used in conditions where there is a deficiency or dysfunction in the clotting cascade. Vitamin K: Mechanism: Essential for γ-carboxylation of certain glutamate residues in clotting factors II, VII, IX, and X, as well as proteins C and S. Use: Vitamin K deficiency, warfarin reversal, hemorrhagic … Read more
