Ximelagatran showed good efficacy compared with warfarin in several trials in prevention and treatment of deep vein thrombosis and as thromboprophylaxis in atrial fibrillation. [1] Development was stopped by manufacturer AstraZeneca , however, because of reports of liver enzyme derangements and liver failure .
ATC code B01 Antithrombotic agents is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. [1] [2] [3] Subgroup B01 is part of the anatomical group B Blood and blood forming ...
[44] [45] Bilateral DVT refers to clots in both limbs while unilateral means only a single limb is affected. [46] DVT in a leg above the knee is termed proximal DVT . DVT in a leg below the knee is termed distal DVT , also called calf DVT when affecting the calf, [47] [48] and has limited clinical significance compared to proximal DVT. [49]
Most of those drugs are in the class of direct factor Xa inhibitors, but there is one DTI called AZD0837, [26] which is a follow-up compound of ximelgatran that is being developed by AstraZeneca. It is the prodrug of a potent, competitive, reversible inhibitor of free and fibrin-bound thrombin called ARH0637. [ 18 ]
Warfarin should not be given to people with heparin-induced thrombocytopenia until platelet count has improved or normalised. [39] Warfarin is usually best avoided in people with protein C or protein S deficiency, as these thrombophilic conditions increase the risk of skin necrosis, which is a rare but serious side effect associated with ...
The ATC system also includes defined daily doses (DDDs) for many drugs. This is a measurement of drug consumption based on the usual daily dose for a given drug. According to the definition, "[t]he DDD is the assumed average maintenance dose per day for a drug used for its main indication in adults." [15]
The abbreviation DVT/PE refers to a VTE where a deep vein thrombosis (DVT) has moved to the lungs (PE or pulmonary embolism). [4] Since the veins return blood to the heart, if a piece of a blood clot formed in a vein breaks off it can be transported to the right side of the heart, and from there into the lungs.
A right-sided acute deep vein thrombosis (to the left in the image). The leg is swollen and red due to venous outflow obstruction. The most common conditions associated with thrombophilia are deep vein thrombosis (DVT) and pulmonary embolism (PE), which are referred to collectively as venous thromboembolism (VTE).
