by What are Anticoagulants?
Clotting inhibitor, also known as blood thinners, are medications that prevent or reduce blood clots from forming in the blood vessels and coronary arteries. They work by interfering with the clotting factors in the blood and preventing the formation of thrombin, which is critical for clot formation. Common clotting inhibitor include heparin, low molecular weight heparins (LMWH), warfarin (Coumadin), and the newer oral clotting inhibitor known as direct oral clotting inhibitor (DOACs).
Types of Anticoagulants
Clotting inhibitor come in different types that vary in how long they take to start working, how long their Anticoagulants last, and how they are administered and monitored. The main types of clotting inhibitor include:
Heparin and Low Molecular Weight Heparins (LMWH)
Heparin is usually given by injection under the skin or into veins. Its effects start working immediately but only last a few hours. LMWHs like enoxaparin (Lovenox) are easier to use as they are given by injection under the skin and have less bleeding risks than heparin. However, their effects also only last up to 12 hours.
Warfarin (Coumadin)
Warfarin is a vitamin K Anticoagulants that works differently than heparin-based clotting inhibitor. It is taken orally as a pill and takes at least 2-5 days to achieve its full anticoagulant effect in the body. Its effects also last longer (2-5 days) and it requires regular monitoring of the INR (International Normalized Ratio) blood test to ensure it remains within the therapeutic range.
Direct Oral Clotting inhibitor (DOACs)
The newer DOACs like apixaban (Eliquis), rivaroxaban (Xarelto), dabigatran (Pradaxa), and edoxaban (Savaysa), provide alternatives to warfarin. They work directly on specific clotting factors and do not require routine INR monitoring. However, their effects still last longer (half-life of 8-17 hours) than heparins and monitoring may be needed is serious bleeding occurs.
Medical Conditions Treated with Clotting inhibitor
Clotting disorders and conditions associated with increased risk of forming clots can be treated or prevented with anticoagulant medications. Some of the main conditions for which clotting inhibitor may be prescribed include:
Atrial Fibrillation
A common heart rhythm problem where the heart’s two upper chambers quiver instead of beating effectively. This significantly increases the chances of blood clots forming and leading to strokes. Clotting inhibitor help prevent clots.
Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE)
Blood clots that form in the deep veins, usually in the legs (DVT), that can dislodge and flow to the lungs (PE), blocking blood flow. Clotting inhibitor are given to treat existing clots and prevent new ones from forming.
Mechanical Heart Valves
When one of the heart’s valves is replaced surgically with an artificial or mechanical valve, clotting inhibitor must be taken lifelong as mechanical valves increase clotting risk. Without anticoagulation, dangerous clots could form on the replacement valve surface.
Myocardial Infarction or Heart Attack
Following a heart attack, anticoagulation may be prescribed short term to decrease the risk of clots forming in the damaged heart tissue which could lead to future heart attack or strokes.
Other Conditions
Other conditions where clotting risks are elevated and clotting inhibitor may benefit include leg fractures, inherited blood clotting disorders, strokes caused by clots, clots during pregnancy and cancer. In all cases, clotting inhibitor help decrease the chance of new clots developing or existing clots from growing larger.
Benefits and Importance of Anticoagulant Therapy
The most important benefit of taking clotting inhibitor as prescribed is the significant reduction they provide against life-threatening blood clots. Some key advantages of anticoagulant medications include:
– Reduced risk of strokes, heart attacks, DVTs and PEs in patients at high risk for clots. Regular anticoagulation offers up to a 90% decreased risk of these dangerous events.
– Prevention of new clots from forming following an initial clotting event like DVT, pulmonary embolism or stroke. Continued therapy is paramount to stop repeat episodes.
– Less postoperative clotting for those with mechanical heart valves or who undergo other high clotting risk procedures like hip or knee replacements or cancer treatments.
– Improved survival and decreased disability from atrial fibrillation and other cardiac conditions where anticoagulation therapy is critical. Proper anticoagulation has significantly reduced stroke risk in AF patients.
– Extended lifespan for those dependent on anticoagulation therapy due to conditions necessitating lifelong treatment. Dramatic reductions in clotting deaths have been observed.
Clotting inhibitor have become an indispensable tool for treating and preventing blood clots, reducing mortality, and improving quality of life for millions worldwide affected by thrombosis. However, close physician supervision is still needed due to bleeding risks. With adherence to prescribed therapies and dosing schedules, anticoagulation can be highly beneficial.
Bleeding Risks Associated with Anticoagulant Use
While significantly reducing ischemic complications, clotting inhibitor unfortunately increase the risk of bleeding events due to their inhibition of the clotting cascade. Some important issues regarding bleeding risks include:
– All clotting inhibitor increase chances of bruising and bleeding from minor cuts or injuries that otherwise stop bleeding normally. Caution must be exercised.
– More serious bleeding risks include gastrointestinal bleeding from ulcers or tears in the stomach/intestines, cerebral hemorrhages, and bleeds in organs, muscles or joints.
– Bleeding risk is elevated when anticoagulant levels are too high, such as due to missed doses, drug interactions, or kidney/liver failures altering drug breakdown and elimination.
– Medications like anti-inflammatories (NSAIDs), antiplatelets (aspirin), and many herbs and supplements can interact and multiply bleeding tendencies. Physician guidance is paramount in medication choices.
– Invasive procedures or surgeries carry a high risk of bleeding complications for those on clotting inhibitor, necessitating interruption or bridging with other therapies before and after such events under medical supervision.
bleeding occurrences often require dose adjustments or transitioning to other anticoagulant options with less bleeding propensity. Reversing agents may also be administered in emergency bleeding scenarios
