DRUGS USED TO TREAT ANEIMA Flashcards
Drugs to treat anemia
Iron
B12
Folic acid
HGF:erytoctye stimulatn agent
Drugs to treat neutropenia
Myeloid growth factor : G-CSF : Filgrastim
GM:CSF:Sargramostim
Drugs to treat/prevent thrombocytopenia
Megakaryocyte growth factors : IL-11Q
Distingushing featrue of iron defeciency (type of anemia , Lap)
Microcytic hypochromic with MCV < 80fL and MCHC <30%
Lap : Low SI <30 mcg/dL
increased TIBC
Result in a tranferrin saturation of < 10 % ; low serum ferritin level <20 mcg/L
in conc : dec Hb dec MCV dec ferritin dec serum iron /TIBC
Hemoglobin >13,5 g/dl in males and >12.5 g/dl in female
MCV > 80fL
hematocrit : <41% in males and <36% in females
Distingushing featrue of B12 (type of anemia , Lap)
Macrocytic nor-mochromic with MCV > 100fL norma MCHC
Lab : Low serum cobalamin < 100pmol/L
increase serum homocysteine > 13 mol/L
increase serum
increase urine methylmalonic acid >3.6 creatininie
Distingushing featrue of folic acid (type of anemia , Lap)
low serum floic acid <4 ng/mL
Low iron is due to what and clinical presentetion
low intake
blood loss
increase req during pregnency
pallor fatigue dizziness exetrioncal dyspnea tachycardia
how do iron absorbed
1- where :
2-by which channel and what cell
3-What happen to heme iron when they enter
4-it is actively transported into the blood by
5- in the blood it is transported by and how enter the bone marrow
6- iron is stored as
7- how to estimate toal iron stores
1-duodenym and proximal jejunum
2-Ferrous is by DMT
Heme iron by HCP1
3-iron get released from heme
4-actively transported into the blood by ferroportin
5-by transferrin and by endocytosis
6-ferritin
7-serum ferritin level
weird uses of iron suplment
for hookworm
Drugs for oral iron therapy
dose
AE
Ferrous sulfate gluconate fumarate
dose : 200- 400 mg daily for 3-6 months
AE: nausea epigastric discomfort abdominal cramps and comstipation and diarrhea black stool
Drugs for PARENTERAL iron therapy
used in? why we use it insted of oral
dose
AE
IRON DEXTRAN - SODIUM FERRIC GLUCONATE - IRON SUCROSE
1-with patient who unable to tolerate or absorb iron
e.g. (postgatrectomy - IBD )
DOSE : IM OR IV 50MG/ML
AE:headache ligh headedness fever arthlgias back pain . urtocaria (rash around the inj) bronchospasm .anaphylaxix
Folate deficiency often due to ?
decrease oral intake and increast utilization or impared absorbtion
Folate feciciency occur in which patheint
Alcoholic and elderly
IBD + Amyloidosis
pregnent cancer and sickle cell aneima beacuse there is an increase in utilization
drug that induce folate feficiency
drug that induce folate feficiency ? 4
Methotrrexate
Trimethoprim———
:——–>inhibit dihydrofolate reducate
pyrimethamine ——
Long-term therapy with phenytoin
folate deficiency symptoms
Glossitis
