How do Carbonic Anhydrase Inhibitors Affect Diuresis |
|
Definition
Carbonix Anhydrase converts bicarbonate and carbonic acid into CO2. Inhibitors of this enzymes stop this conversion.
Bicarbonates and Carbonic acid are less permeable, thus they do not get resorbed, increasing the volume excreted.
|

|
Definition
Prothrombin-->becomes Thrombin |
|
|
Term
What chemical does thrombin activate and what is its activated form? |

|
|
Term
Name 3 Anticoagulant Agents and their route of administration |
|
Definition
1. Warfarin-ORAL
2. Pentoxifylline-Oral
3. Heparin-IV |
|
|
Term
What is a healthy INR range? What can happen if a pt is below this range? Above? |
|
Definition
INR stands for International Normalized Ratio and refers to blood coagulation ability. A good range is from 2-3. Being below this range refers to underanticoagulation and can result in blood clots-->stroke
Being above this range can result in blood that is too thin and thus an increased risk of bleeding. |
|
|
Term
How does Heparin affect blood clots? |
|
Definition
Heparin inhibits the conversion of prothrombin to thrombin and thus the covnersion of fibrinogen to fibrin-->thus preventing blood clots |
|
|
Term
|
Definition
Bleeding
Hypersenstivity
Thrombocytopenia |
|
|
Term
How does Low Molecular Weight (LMW) Heparin compare to standard heparin? |
|
Definition
LMW heparin is derived from standard heparin , it has a greater bioavailability, longer duration of action and fewer SE. |
|
|
Term
What drug is used to treat an overdoes of Heparin? |
|
Definition
|
|
Term
What is the mechanism of action of warfarin? |
|
Definition
Warfarin resembles vit. K and thus it interferes with the synthesis of certain clotting factors that are dependent on vitamin K. |
|
|
Term
Which drug is used for more long term anticoagulant treatment? |
|
Definition
Warfarin ( as opposed to Heparin) |
|
|
Term
How does the action of anticoagulants compare to that of anti-platelets? |
|
Definition
Anticoagulants prevent thrombosis in veins, antiplatelets prevent clot formation in arteries. |
|
|
Term
How does Dipyridamole impair platelet function? |
|
