Etiologies for Anemia are: |
Decreased formation of RBC Decreased Hb concentration Chronic blood loss Hemolysis Bone marrow abnormalities Nutritional deficiency |
|
What is the most common Anemia |
Nutritional anemia specifically Iron deficiency anemia |
|
In all anemias we will see.... |
microscopically hypchromic microcytic red blood cells small and pale red blood cells |
|
Treatment for Iron deficiency anemia is |
Oral Fe++ supplement as ferrous sulfate |
|
Iron defficiency anemia can be due to: |
acute or chronic blood loss increased demand as in accelerated growth heavy menstruation or pregnancy |
|
Folic acid deficiency anemia is due to: |
increased demand in pregnancy and lactation poor absorption alcoholism tx with dihydrofolate reductase inhibitors such as methotrexate and trimethropin |
|
Treatment for folic acid deficiency anemia is: |
folic acid supplements |
|
Cyanocobalamin Vit B12 is the same as : |
Pernicious Anemia |
|
This anemia is due to no production of intrinsic factor |
Pernicious anemia |
|
Pernicious anemia is associated with |
neurologic manifestations |
|
Both cyanocobalamin vit B12 and folate deficiency anemias present |
megaloblastic cells a blood test is necesary to distinguish them |
|
Glycoprotein, kidney hormone that stimulates erythropoiesis |
Erythropoietin |
|
Uses for Erythropoietin |
End stage renal disease pts so they can produce the adequate amount of rbcs HIV pts |
|
Hydroxyurea is used for: |
chronic myelogenous leukemia polycitemia vera in sickle cell anemia where it increases the concentration of fetal hemoglobin to dilute the concentration of HbS.` |
|
Name the 7 platelet aggregator inhibitors |
Aspirin Dipirydamole Ticlopidine Clopidrogel Abciximab Eptifibatide tirofiban |
|
What are platelet aggregator inhibitors good for? |
used in prevention and treatment of cardiovascular diseases mainteneance of vascular grafts |
|
How does aspirin work? (platelet aggregator inhibitor) |
It inhibits IRREVERSIBLY the cycloxigenase pathway this way suppresing Thromboxane A2 |
|
How long does the effct of aspirin last? |
7-10 days a loading dose should be used followed by smaller maintaneance doses. |
|
This coronary vasodilator is used Prophylactically in CAD (angina) (platelet aggregator inhibitor) |
Dipirydamole |
|
How does Dipirydamole work? platelet aggregator inhibitors |
It increases cAMP levels to reduce the formation of Thromboxane A2 |
|
This drug is effective in combination with warfarin preventing embolization in prosthetic heart valves ( platelet aggregator inhibitors ) |
Dipyridamole |
|
These 2 platelet aggregator inhibitors block the ADP pathway involved in binding the platelets to fibrinogen. |
Ticlopidine Clopidrogel |
|
these 2 platelet aggregator inhibitors are for people who were treated with aspirin before. |
Ticlopidine clopidrogel the chances of bleeding after discontinuation of these drugs are less than with aspirin |
|
Ticlopidine and Clopidrogel are used for? side effects are? platelet aggregator inhibitors |
prevent CVA, CVD, PVD used in stent insertion s.e neutropenia inhibition of CYP 450 |
|
Monoclonal antibody against GpIIb/IIa complex blocking the binding of factors I and X to block platelet aggregation |
Abciximab |
|
How do you use Abciximab? platelet aggregator inhibitors |
IV effect persists for 24-48 hrs |
|
What is the most common S.E of Abciximab? platelet aggregator inhibitors |
Bleeding |
|
These 2 platelet aggregator inhibitors have less side effects |
Eptifibatide tirofiban |
|
This drug is a vit K antagonist that has a rapid oset of action indirectly binding to antithrombin III which inhibits the activation of several clotting factors |
Heparin (Anticoagulant) |
|
This anticoagulant is the drug of choice during pregnancy |
Heparin it doesnt cross the blood brain barrier |
|
Clinical uses for Heparin |
deep vein thrombophlebits pulmonary embolism exracorporeal devices |
|
Anticoagulants should never be administered |
IM because they may cause hematomas |
|
Adverse side effects of Heparin |
Hemorrhage hypersensitivity thrombocytopenia Do not use during post operative stages (eye, brain, or spinal cord) |
|
A pt has been taking heparin, which caused him to have a hemorrhage, what drug can you give him to stop this? |
Protamine sulfate |
|
This anticoagulant is rat poison |
Warfarin |
|
Anticoagulant that antagonizes the function of Vit K, it blocks factors that depend on it |
Warfarin |
|
How much time after administration does it take Warfarin to work? |
8-12 hrs |
|
this anticoagulant binds 99% to albumin |
Warfarin |
|
Bleeding caused by this drug can be treated with Vit K, fresh frozen plasma and specific blood factors |
Warfarin also dont use this on pregnant women, its teratogenic |
|
What drugs inhibit the metabolism of Warfarin in serum? |
Acute alcohol intoxication cimetidine chloramphenicol cotrimoxazole Metronidzole Phenylbutazone Disulfiram |
|
Drugs that stimulate the metabolism of Warfarin are: (reduce it in serum) |
Chronic alcohol Ingestion Barbiturates Clutethimide Griseofulvin Rifampin |
|
What is Thrombin? |
Its one of the proteins necessary for the end process of producing stable blood clots. it activates fibrinogen. |
|
This anticoagulant is a thrombin antagonist with little or no activity on platelet function |
Lepirudin s.e decreases renal function |
|
