what is coagulating agent?which is best coagulating agent?

Answer 1

A coagulating agent are those things that make the blood clots. If we don't have coagulating agent, when we cut our skin or been stab, blood will not stop flowing. There are plenty of coagulating agent but they are subdivided into factors depending on the need of your body. If you lack of this agent, somethings is wrong with your body.

Answer 2

Coagulating Agent

Answer 3

Coagulating agent makes something coagulate from a solution. An example is fresh egg white. It coagulates mercury.

Answer 4

Coagulating agent in not only restricted to blood.

Its has to mainly deal with colloids.
Particles based on sizes are divided into true solution,cooloids and suspensions.

suspensions -very large particles

True -extremely small mixed thoroughly with solution

colloid -average ,in between the two.

Blood is a form of colloid having dispersed phase and dispersion medium,other include gel,foam,cloud,milk soap..................

Colloidal particles are charged and repel each other.However if the are made to loose their charge,the form the can be gathered together to form a mass.The agent used for this purpose is coagulating agent.
Alum is one of the coagulating agent we use for purifying water from harmful colloidal particles.

There is nothing as best agent as diff agents are suitable for diff purposes.

Answer 5

anticoagulant is a substance that prevents coagulation; that is, it stops blood from clotting. A group of pharmaceuticals called anticoagulants can be used in vivo as a medication for thrombotic disorders. Some chemical compounds are used in medical equipment, such as test tubes, blood transfusion bags, and renal dialysis equipment..
Anticoagulants are given to people to stop thrombosis (blood clotting inappropriately in the blood vessels). This is useful in primary and secondary prevention of deep vein thrombosis, pulmonary embolism, myocardial infarctions and strokes in those who are predisposed.


Vitamin K antagonists
The oral anticoagulants are a class of pharmaceuticals that act by antagonizing the effects of vitamin K. It is important to note that they take at least 48 to 72 hours for the anticoagulant effect to develop fully. In cases when an immediate effect is required, heparin must be given concomitantly. Generally, these anticoagulants are used to treat patients with deep-vein thrombosis (DVT), pulmonary embolism, atrial fibrillation, and mechanical prosthetic heart valves.

These oral anticoagulants are used widely as poisons for mammalian pests, especially rodents. (For details, see rodenticide and warfarin.)

The most important oral anticoagulants are:

Warfarin (Coumadin). This is the main agent used in the U.S. and UK
Acenocoumarol and phenprocoumon This is used more commonly outside the U.S. and the UK
Phenindione

Heparin and derivative substances
Heparin is a biological substance, usually made from pig intestines. It works by activating antithrombin III, which blocks thrombin from clotting blood. Heparin can be used in vivo (by injection), and also in vitro to prevent blood or plasma clotting in medical devices. Vacutainer brand test tubes containing heparin are usually colored green.

Low molecular weight heparin is a more highly processed product that is useful as it does not require monitoring of the APTT coagulation parameter (it has more predictable plasma levels) and has less side effects.

Fondaparinux is a synthetic sugar composed of the five sugars (pentasaccharide) in heparin that bind to antithrombin. It is a smaller molecule than low molecular weight heparin.


Direct thrombin inhibitors
Another type of anticoagulant is the direct thrombin inhibitors. Current members of this class include argatroban, lepirudin, and bivalirudin. An oral direct thrombin inhibitor, ximelagatran (Exanta®) may replace warfarin for some indications. It is awaiting Food and Drug Administration (FDA) approval.

It is something that either causes existing groups of molecules to stick together, making the solution thicker, or causes a chemical reaction making larger molecules that then stick together. Either way, the solution becomes thicker and may also separate into a thin layer and a thick or even solid one.
