Home » Prescription Drugs 1 » Acitrom Sinthrom Nicoumalone tablets contain the active ingredient acenocoumarol (previously known as nicoumalone in the UK) which is a type of medicine called an oral anticoagulant. It is used to stop blood clots forming within the blood vessels. Blood clots normally only form to stop bleeding that has occurred as a result of injury to the tissues. The clotting process is complicated and begins when blood cells called platelets clump together at the site of damage and produce chemicals that activate clotting factors in the blood. Clotting factors are proteins that are produced by the liver. Vitamin K is essential for their production. The activated clotting factors cause a protein called fibrinogen to be converted into another called fibrin. Fibrin binds the platelets together forming a blood clot. This is the bodyÆs natural way of repairing itself. Sometimes however a blood clot can form abnormally within the blood vessels. This is known as a thrombus and can be dangerous because the clot may detach and travel in the bloodstream where it becomes known as an embolus. The clot may eventually get lodged in a blood vessel thereby blocking the blood supply to a vital organ such as the heart brain or lungs. This is known as a thromboembolism.Some people have an increased tendency for blood clots to form within the blood vessels. This is usually due to a disturbance in the blood flow within the blood vessels. For example fatty deposits on the walls of the blood vessels (atherosclerosis) can disrupt the blood flow giving a tendency for platelets to clump together and start off the clotting process. Slow blood flow in the leg and pelvic veins can also result in clots forming (deep vein thrombosis). These clots can break off and travel to the lungs (pulmonary embolism). A type of fast irregular heartbeat called atrial fibrillation can also disrupt blood flow and may lead to blood clots forming in the heart. Heart valve disease can have the same effect particularly if artificial heart valves have been fitted. Clots in the heart can detach and travel to the brain causing a stroke. Acenocoumarol is used to reduce the risk of blood clots forming inside the blood vessels in conditions such as these. Acenocoumarol works by preventing the vitamin K dependent production of the clotting factors described above. Acenocoumarol prevents the production of these clotting factors by inhibiting the action of vitamin K. Without these clotting factors fibrinogen cannot be converted into fibrin and blood clots are therefore less likely to occur.Acenocoumarol takes about three days to produce its full anticoagulant effect because while it prevents the production of new clotting factors it takes about this long for clotting factors that have already been produced to be used up. For this reason when treating blood clots such as deep vein thrombosis (DVT) or pulmonary embolism a faster acting injectable anticoagulant such as a heparin is often used as well to begin with.The anticoagulant effect of acenocoumarol is measured in terms of the prothombin time which is the time taken for blood clotting to occur in a sample of blood to which calcium and a substance known as thromboplastin have been added. This time is expressed as the International Normalised Ratio (INR). Your doctor will take regular blood samples and adjust your dose of acenocoumarol as necessary to make your INR fall into the range that has been shown to be effective at preventing blood clots in your particular condition.What is it used for?Treating and preventing blood clots in the blood vessels for example in the following cases:Preventing abnormal blood clots in conditions with increased risk eg rheumatic heart disease atrial fibrillation and after insertion of artificial (prosthetic) heart valves Treatment and prevention of blood clots lodged in the veins of the leg (deep vein thrombosis) Treatment and prevention of blood clots that have travelled to the lungs (pulmonary embolism) Buy Acitrom Sinthrom and other Prescription Drugs 1 products online at Medstore.

View more Prescription Drugs 1 Pharmacy: Dozens of patents for name-brand drugs are due to expire within the next 14 months, and generic drugs will replace some of the most popular and widely advertised drugs used today. For millions of people worldwide, this means switching from familiar brands like Lipitor to generic equivalents. How will this affect drug companies, and what will be the impact on people who depend on expensive prescription medication? Here, a brief guide: Which drugs are scheduled to go generic? Some real blockbusters. "In the next two years, six of the 10 top-selling drugs will lose their patents," says Chris Woolston in the Los Angeles Times. Lipitor, the world's best-selling drug, which is used to lower cholesterol, will be available as a generic in November of this year. Another best-seller, the blood thinner Plavix, will lose its patent in May 2012. Other well-known drugs with expiring patents include the arthritis treatment Enbrel, the anti-psychotic Zyprexa, as well as drugs for bipolar disorder, HIV, high cholesterol, and other conditions.
