Anticoagulant
Anything which prevents blood clot formation, such as aspirin
Question: What is the difference between an Anticoagulant and an Anti-platelet Agent medication? My grandad recently had a stroke and I am trying to research all I can on the condition. In researching the possible medications given, I have come across the terms Anticoagulant and Anti-platelet Agents, but their definitions seem to be very similar. Are they simply different names for the same thing or do they have differences?
I would be grateful for any help. Thank you.
Answer: You're right. Anticoagulants and antiplatelet drugs are both meant to do the same job, but by a different mechanism.
Anticoagulant drugs typically target proteins in our blood that work together to convert fibrinogen into fibrin (a key ingredient in blood clots). For example, heparin and similar drugs help increase the action of anti-thrombin III, which is a blood chemical that naturally inactivates many of the proteins that I mentioned earlier.
Other anticoagulants include coumarin, and streptokinase.
Antiplatelet drugs work by targeting platelets directly. These drugs usually work by binding to, and blocking receptors on the surface of platelets. Normally, these sites are activated by mediators released by damaged tissues, and the platelets respond by sending out lots of chemicals that result in venospasm, inflammation, and blood clotting. So antiplatelet drugs prevent this from occurring.
Some antiplatelet drugs include clopidogrel (plavix), ticlopidine, abciximab, eptifibatide, tirofiban, and dipyridamole.
Aspirin is probably an antiplatelet drug to. It works by inhibiting COX-2 within platelets and preventing them from synthesizing thromboxane A2 which is necessary for the activation of platelets. Aspirin is cheap and safe and should probably be considered a super-drug for people in need of anticoagulation.
Hope that helps.
Question: Why does a patient having anticoagulant therapy have to have blood drawn every week? A patient on outpatient anticoagulant therapy asks why he has to have blood drawn every week. What is the most appropriate response by the nurse?
Answer: They are checking for how well the blood clots, too well - give more medication;
too little - cut back on medication.
Question: What would a blood sample with anticoagulant look like after 30 min? The blood was transferred to vials with anticoagulant after extraction. After a while, what would the sample look like? Will it have significant changes in appearance or will it essentially be the same?
Answer: I believe it would be thinner
Question: What is the name of the substance/chemical(anticoagulant) that is added to keep blood from cloting? In blood transfussion & in donating blood, an anticoagulant agents are added to the blood to keep it from cloting. Do you which are they ?
Answer: They are anti-coagulants. They keep the blood from "coagulation" or clotting.
There are different forms of these. Some are used as medicines to keep the blood thin in people with diseases of excessive blood clotting or who have blood clots (like, heart attack or stroke patients).
But the use you have mentioned is entirely different. The anti-coagulants used OUTSIDE the body in tubes and bags where they keep the blood for transfusion etc. are different. These are EDTA, Citrate (eg: Sodium Citrate), Oxalate.
Question: Do all people diagnosed with the disease Lupus test positive to lupus anticoagulant as well? I know that a positive lupus anticoagulant test doesn't mean that a person has Lupus, but i wonder if people with lupus have the lupus anticoagulant too?
Answer: well i have lupus and to answer your question lupus anticoagulants are often found in people who have systematic lupus erythematosus, which is also called SLE.
Question: Where can I buy a liquid anticoagulant? I bought a blood vial necklace but I don't want the blood to rot or coagulate.. Is there a liquid anticoagulant that I can add to the vial with the blood?
Answer: Ginger and aspirin(dissolved first) are both natural anticoagulants. However, you would be better off getting a doctor to draw the blood up with an anticoagulant already in it, as this would be much much more effective. Other than that, all the other AC's are prescribed medicines and would require a doctors RX.
Question: What is the usual % of red cells in a tube of whole blood collected in Anticoagulant? I need so major help on my Immuno homework and have no idea how to approach the problems in it. This is one of them.
if you could help explain where you get your answer that would be lovely. Thank you so much in advance.
Answer: The % rbcs in a centrifuged sample of whole blood is called the hematocrit, and is makes up approximately 45-50% of the blood volume. Females have a slightly lower HCT than males. Any decent hematology text or website should be able give you more details.
Question: What to expect with a diagnosis of Purpura Fulmicans and Lupus Anticoagulant w/possible Phophosilid syndrome? My 20 month old daughter was recently diagnosed with this in a Children's Hospital she was sent to. I've looked on line, but I can't find anything on living with it, life expectancy, or any preventative measures to take. All I can find is some descriptions and a few pictures. I know it's rare, but surely someone can give me some advice.
Thanks.
Answer: God, I'm so sorry about the diagnosis. Purpura Fulmicans is usually associated with some underlying infection such as meningitis. It can decrease the blood flow/pressure, sometimes causing digits to be amputated. The Lupus Anticoagulant/Antiphospholipid Syndrome is a clotting disease that can be treated with blood thinners/aspirin. Blood clots are common in people with APS and early onset usually implies greater complications.
The primary issue is finding the underlying cause of the Purpura Fulmicans and treating it. Usually this will subside after the cause is treated. APS is a different story and is a lifelong issue. There is a much higher rate of heart attack and stroke in people with APS, however, with vigilant treatment lifespan can be normal.
My wife has APS and Lupus and is doing just fine. She has had two blood clots and a heart attack but survived them all because we knew what was going on.
Question: what foods should a person taking anticoagulant medicines control? cold water fish, processed soups, enriched breads , or green leafy vegetables? which one of those should a person taking this medication control their intake of?
Answer: It's leafy green vegetables
Question: Chance of conceiving if one has lupus anticoagulant and PCOS? What is the chance/probability of conceiving if one has Lupus Anticoagulant [[Auto-immune]] and PCOS?
Answer: That sounds like a question for a high risk OBGYN Doctor. I will share though, that I have both PCOS and a postive lupus anticoagulant. I have three children!
Question: why would a client be in danger if they were taking salicylates with an anticoagulant? why would a client be in danger if they were taking salicylates with an anticoagulant?
Answer: Lawyers have clients. Doctors, Pharmacists and Nurses have patients. Salicylates inhibit platelet aggregation and anticoagulants prolong clotting time. The patient is at risk of hemorrhaging when the two compounds are taken together.
Question: Is the vampire bats adapatation of having and anticoagulant in its saliva physiological or structural? I'm just not sure which it fits into. Any help would be appreciated thanks. :)
Answer: That is physiological. Structural adaptations include the sharp teeth that make the incision through which the saliva is introduced.
Question: Is the best way to preserve donated blood is by adding anticoagulant & refrigerated or at a room tempreture ? What the temp. should be in order for the donated blood not to loose its quality & have a longer life span, in case needed for transfusion ?
Answer: yes they put anticoagulants, and blood is in refrigerator, the temp differ from type to type, not from type of blood but from content like fresh frozen plasma, or platelet,
Question: As in the movie Untraceable, what would really happen during someone dying from an anticoagulant? In the movie Untraceable, the first human victim died by having an anticoagulant continuously given to him by an IV while being chained up. This made me wonder, in real life, what's the series of events that would happen to someone health-wise while being given a constant dosage of an anticoagulant before they actually die and how painful?
Answer: After Iron poisoning in children, Its actually the most common form of overdose - quite often unintentional. Its also the most common form of suicide. My best friend when I was a teen died this way.
Never saw the movie
here is the emed report for one of them...

Question: What is the most important natural body anticoagulant?
Answer: 1)prostacycline (a platelet repellent) smoothness of endothelium surface .
2)glycocalyx
3)thrombomodulin that stop thrombin to bind with fibrinogen
4)heparin (which increase antithrombin activity)
Question: What is an anticoagulant and give two examples? Biotechnology,Microbiology n biology related topic.
Answer: there's 2 mechanisms by which your blood clots:
1. platelet aggregation- those are the cells that clump together
2. clotting factors- those are the proteins that react to damaged endothelium and form fibrin clots.
if you inhibit either one, you can prevent blood clots. examples of anti-platelet drugs are aspirin, plavix, or dipyridamole. examples of clotting factor inhbitors are warfain, heparin, or lovenox.
Question: What does an anticoagulant do? and how is it useful to doctors? In the terms of mosquitoes? i dont know, i need some simple wording answers
Answer: mosquitoes saliva contains an anticoagulant which as you know prevents blood from clotting, this aids the mosquito feeding on the host's blood.
Anticoagulants are used by doctors in the treatment of heart disease, where arteries are narrowed and more likely to be blocked by a clot, and treatment of blood clots, by dissolving them, suffered by such as stroke victims also used after surgery to prevent them forming.
Question: Why is anticoagulant NOT added to the blood towards the END of a DIALYSIS SESSION? its an exam question
i know its needed as the blood is pumped into the machine but why not at the end?
Answer: Because the blood is going back into the body, so it'll need to have the option of coagulation if there's some sort of trauma.
Question: can Lupus Anticoagulant be detected before a miscarriage occurs? My sister just had a miscarriage due to this Lupus Anitcoagulant Sydrome and she is very health and all was well with the baby and we just dont understand how this happened. i cant find ansawer for my question any that i have looked and i was wondering if any could give me a link on where to look or please if u have the answer please let me know! Thank you in advance!
Answer: Some lupus patients have clotting disorders. They can be detected by a blood test. Unless a doctor knows the patient has lupus and suspects a clotting disorder, they will not test for it. The clotting disorders include antiphospholipid antibodies, lupus anticoagulant and anticardiolipin.
Women with these disorders can have children. The pregnancies are considered high risk and need to be monitored by an obstetrician who handles high risk pregnancies in conjunction with her rheumatologist.
