17
Q

role of thrombomodulin

A

attaches to 2a and then attaches to protein c and then it cleaves 8a and 5a so that the rest of the coagulation pathway cannot occur and a clot won’t happen

18
Q

role of tPA

A

tPA takes plasminogen from the liver and turns it into plasmin and then it chops 1a (fibrin) into tiny pieces causing it to become a “Fibrin Split Product”

19
Q

4 Thrombolytic Drugs (tPA analogues)

A

Streptokinase
Urokinase
Alteplase
Retaplase

20
Q

risk factor for thrombolytic

A

excessive bleeding

21
Q

what do thrombolytics do

A

they induce the change of plasminogen to plasmin

22
Q

what is the drug that inhibits tPA

A

Aminocarpuic Acid

23
Q

first response to BV damage

A

neurogenic vasoconstriction

24
Q

2nd response to BV damage

A

endothelia release (vasoconstriction)

25
3rd response to BV damage
vWF upregualtion
26
GP1b binds to what
vWF
27
what happens when Gp1b binds to vWF
Cox pathway is stimulated and TXA2 is produced
28
what does thromboxane A2 do
causes the degranulation of the alpha and delta cells in the platelets so that ADP can be released
29
what does ADP and ADP receptors on the platelet cells fo
causes the up regulation of GPIIb-IIIA
30
what blocks the cox pathway
aspirin
31
4 ADP Receptor (platelet) blocker drugs
Ticlopidine Clopidogrel Prasugrel Ticagrel
32
3 GPIIb-IIIa receptor inhibitors
Abciximab Epitifibatide Tirofiban
33
drugs for von wilder brand disease
desmopressin vasopressin *factor 8
34
Gp1b deficiency is called
Bernard Solier
35
GpIIIa deficiency is called
Glanzmen Disorder
36
what factor activated factor 13
1A
37
WHAT forms mesh work around clot
factor 13
38
Drugs that inhibit Factor 10 (3)
Heparin Riveroxaban Apixaban
39
Direct Thrombin inhibitors
Argatroban | Bivalrudin
40
phosphodiesterase 3 inhibitor
Cilostazole
