Anticoagulants are medications that contribute to the dilution of the blood consistency. They contain chemical components that reduce blood clotting or increase the clotting time itself. This property is associated with the liquefaction effect, which is often used for medical purposes. Contains anticoagulant in some living creatures that feed on blood (mosquitoes, leeches), it allows them to get enough blood, preventing it from clotting at the site of the bite. In medical practice, anticoagulants are used to treat diseases associated with the occurrence of thrombosis. Preparations in tablets are used to treat various forms of diseases, and intravenous forms are used exclusively in the hospital. A simple example would be the intravenous administration of medicinal solutions or blood products into an established catheter in the subclavian artery. After the end of the introduction, the catheter is filled with an anticoagulant to prevent its thrombosis.
When is it important to buy anticoagulant?
Some types of this group of drugs are necessary for the normal operation of medical equipment (blood bags for transfusion, dialysis machines). Anticoagulants are used with such groups of drugs as thrombolytic and antiagregatny. Each group has its own effect on blood clotting, as antithrombotic substances contribute to platelet adhesion, while anticoagulants have a direct effect on blood clotting factors. The most famous drugs in this group are heparin and warfarin, they are part of most medicines, being used as the main active ingredient.
How is anticoagulant used in medical practice?
The use of drugs of this group has several advantages (prevents the formation of thrombosis) and risks (causes bleeding). For the average patient, the risk of bleeding with the introduction of anticoagulants is minimal. It poses a threat to people who have recently undergone surgery, with cerebral aneurysm of blood vessels. Anticoagulants help prevent or significantly reduce the progression of various diseases associated with the formation of blood clots inside the vessels. Anticoagulant therapy is indicated in the following cases:
- Ischemic heart disease (CHD);
- Vein thrombosis that can trigger a pulmonary embolus;
- Myocardial infarction;
- Ischemic stroke;
- Atrial fibrillation (clot formation in the atrium).
In all these cases, taking anticoagulants will help prevent growth and the further formation of blood clots. The decision to start anticoagulation is taken exclusively by the attending physician, weighing all the benefits and risks of its use.
When does the risk of getting a negative effect increase?
The group of patients after 80 years is most susceptible to the occurrence of uncontrolled bleeding after the use of anticoagulants. Purchasing drugs (buy anticoagulant) and their subsequent use can provoke calcification of the arteries and heart valves (lack of vitamin K and an excess of vitamin D in the body). The use of warfarin for patients with an acute stage of renal failure, as well as the presence of atrial fibrillation, significantly increases the risk of bleeding, and can trigger a stroke.
Types of interaction
Some foods and food additives contribute to the dilution of blood, therefore, when prescribing anticoagulants, it is necessary to take into account the possible enhancement of the effect associated with their consumption by the patient. This group includes: beer, green tea, onions, garlic, ginseng, cranberries, blueberries, soybeans, pomegranate, ginger, turmeric, licorice. Many herbs and vitamin complexes have this effect.
