Lecture 4 Flashcards
INR
Assesses Coumadin
PPT
Assesses levels of heparin
Vitamin K
inhibition of this will decrease synthesis of clotting factors
Clot breakdown
Tissue plasminogen activator converts plasminogen to Plasmin (fibrinolysis) breakdown the fibrin mech/clot
BALANCE between formation and breakdown is key for homeostasis
What are the 3 classification of drugs to treat clotting disorders?
Anticoagulants - body’s own thrombolytic (plasma) can bust the clot
Antiplatelet - inhibits lately aggregation
Thrombolytics - clot buster, dangerous
What are the 4 categories of anticoagulants?
1) Direct thrombin inhibitors
2) Indirect thrombin inhibitors
3) Vitamin K epoxide reductase inhibitor
4) Direct Xa inhibitor
What are the 3 categories of antiplatelets?
1) COX inhibitors
2) Glycoprotein lib/IIIa inhibitors
3) ADP inhibitors
What is the one category for thrombolytics?
Plasminogen activators
Due to the slow onset with Coumadin…
Heparin is administers through IV
What is the acceptable ratio for INR?
0.8 - 1.2
MOA: Statin
Increase hepatic uptake of LDLs
Atovastatin blocks liver cholesterol production
CCB
Decreases SA node automaticity, slows AV node conduction velocity and decreases HR
Dig
Increases contractility force of the heart
Increases CO at rest and during exercise
Decrease conduction through AV via vagus nerve
Coumadin
Increase clotting time
