Exam 4 Flashcards
Drugs
Heparin
Anti-coagulant. Enhances antithrombin activity (1000x) which inhibits Xa and thrombin. Reversed by protamine sulfate.
LMW heparin
Anti-coagulant, enhances antithrombin and is more specific for factor Xa inactivation.
Fondaparinux
Anti-coagulant, increases antithrombin. The least efficacious.
Protamine sulfate
Reversal agent for heparin.
Hirudin/ Lepirudin
Anti-coagulant. Derived from leeches also can be made recombinantly. Binds to both active and substrate sites on thrombin.
Argatroban
Direct thrombin inhibitor.
Dabigatran
Bind to thrombin active sites.
Warfarin
Direct thrombin inhibitor. Prevents synthesis of factors 2, 7, 9 ,10 via tampering with redox metabolism of vitamin K. Reversed by vitamin K, factor 9, FFP
Rivaorxaban
Factor Xa inhibitor.
Apixaban
Factor Xa inhibitor.
tPA
Fibrinolytic. Rapidly lyses thrombi. Treatment for ischemic strokes.
Streptokinase
Fibrinolytic
Urokinase
Fibrinolytic
Aspirin
COX inhibitor. Acetylation of Serine 529 residue irreversibly modifies COX1 enzyme from binding with arachidonic acid to form prostaglandins and TXA2. Less platelet aggregation and has some anti-inflammatory effects. High incidence of GI ulcers.
Clopidogrel
ADP inhibitor. Anti-platelet aggregation.
Abiciximab
Mab anti-platelet aggregation.
vitamin K
For warfarin overdose. Helps replenish factors.
Fresh frozen plasma
To replenish factors. For hemophilia.
Aminocaproic acid
Fibrinolytic inhibitor. Targets plasminogen pathway. Clot stabilizer. Used post-operatively.
Tranexamic acid
Anti-fibrinolytic used for massive hemorrhage/ trauma to help stop bleeding.
Lispro and Aspart
Rapid acting insulin
Humulin
Short acting insulin
Neutral Protamine Hagedorn
intermediate acting insulin
Glargine and Detemir
Long acting insulin
