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

This thrombin inhibitor is used prophylactically in heparin induced thrombocytopenia(HIT)

Argatroban

Purely synthetically pentascharide aproved for DVT in orthopedic surgery of hip and knee




may also be used in HIT

Fondaprinux

These agents were originally indicated for


Deep vein thrombophlebitis (DVT)


and acute pulmonary embolism


but now they are also for


acute myocardial infarction (use within 2-12hrs)

Thrombolytic agents




converts plasminogen into plasmin which cleaves fibrin, breaking a thrombi

These agents are contraindicated for pts with a history of CVA, pregnant, metastatic carcinoma

Thrombolytic agents

This throbolytic agent is fibrin selective

Alteplase


it combines with fibrin ina thrombus

Altepase is used for:

acute myocardial infarction


acute ischemic infarct (CVA)

This drug couples 1:1 with plasminogen

Streptokinase

Streptokinase is used for

Acute myocardial infraction
