  <description>Acenocoumarol is an exogenous solid with the formula C19H15NO6 and an average molecular weight of 353.33 g/mol. Acenocoumarol belongs to the hydroxycoumarins, a subclass of coumarins and derivatives within the organic compounds. It is used as an anticoagulant and acts as an inhibitor of EC 1.6.5.2 [NAD(P)H dehydrogenase (quinone)]. This compound is found in amplifiers and in antithrombotic agents within healthcare, pharmaceuticals, and veterinary products, with oral exposure recorded.

The protein targets of acenocoumarol include albumin (ALB), alpha-1-acid glycoprotein 1 (ORM1), and vitamin K epoxide reductase complex subunit 1 (VKORC1). Acenocoumarol inhibits vitamin K reductase, which leads to the depletion of the reduced form of vitamin K (vitamin KH2). Because vitamin K serves as a cofactor for the carboxylation of glutamate residues on the N-terminal regions of vitamin K-dependent proteins, this inhibition limits gamma-carboxylation and the subsequent activation of vitamin K-dependent coagulant proteins. Consequently, the synthesis of anticoagulant proteins C and S, as well as vitamin K-dependent coagulation factors II, VII, IX, and X, is inhibited.</description>

  <route_of_exposure>Ingestion (L1817) ; dermal (L1817). Rapidly absorbed orally with greater than 60% bioavailability. Peak plasma levels are attained 1 to 3 hours following oral administration.</route_of_exposure>
  <mechanism_of_toxicity>Acenocoumarol inhibits vitamin K reductase, resulting in depletion of the reduced form of vitamin K (vitamin KH2). As vitamin K is a cofactor for the carboxylation of glutamate residues on the N-terminal regions of vitamin K-dependent proteins, this limits the gamma-carboxylation and subsequent activation of the vitamin K-dependent coagulant proteins. The synthesis of vitamin K-dependent coagulation factors II, VII, IX, and X and anticoagulant proteins C and S is inhibited. Depression of three of the four vitamin K-dependent coagulation factors (factors II, VII, and X) results in decresed prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots. (A308)</mechanism_of_toxicity>
  <metabolism>Extensively metabolized in the liver via oxidation forming two hydroxy metabolites and keto reduction producing two alcohol metabolites. Reduction of the nitro group produces an amino metabolite which is further transformed to an acetoamido metabolite. Metabolites do not appear to be pharmacologically active. &#13;Route of Elimination: Mostly via the kidney as metabolites&#13;Half Life: 8 to 11 hours.</metabolism>

  <use_source>Acenocoumarol is an anticoagulant drug derived from coumarin. (L1261) For the treatment and prevention of thromboembolic diseases. More specifically, it is indicated for the for the prevention of cerebral embolism, deep vein thrombosis, pulmonary embolism, thromboembolism in infarction and transient ischemic attacks. It is used for the treatment of deep vein thrombosis and myocardial infarction.</use_source>

  <health_effects>#&lt;HealthEffect::ActiveRecord_Associations_CollectionProxy:0x00007f3bcff34258&gt;</health_effects>
  <symptoms>The onset and severity of the symptoms are dependent on the individual's sensitivity to oral anticoagulants, the severity of the overdosage, and the duration of treatment. Bleeding is the major sign of toxicity with oral anticoagulant drugs. The most frequent symptoms observed are: cutaneous bleeding (80%), haematuria (with renal colic) (52%), haematomas, gastrointestinal bleeding, haematemesis, uterine bleeding, epistaxis, gingival bleeding and bleeding into the joints. Further symptoms include tachycardia, hypotension, peripheral circulatory disorders due to loss of blood, nausea, vomiting, diarrhoea and abdominal pains.</symptoms>
  <treatment>The primary antidote to acenocoumarol poisoning is immediate administration of vitamin K1 (initially slow intravenous injections of 10-25 mg repeated all 3-6 hours until normalisation of the prothrombin time; then 10 mg orally four times daily as a "maintenance dose"). It is an extremely effective antidote, provided the poisoning is caught before too much damage has been done to the victim's circulatory system. At high doses  acenocoumarol can affect the body for many months, and the antidote must be administered regularly for a long period of time. (L1257)</treatment>

The synthesis of vitamin K-dependent coagulation factors II, VII, IX, and X and anticoagulant proteins C and S is inhibited. Depression of three of the four vitamin K-dependent coagulation factors (factors II, VII, and X) results in decresed prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots.</mechanism_of_action>

      <mechanism_of_action>Acenocoumarol inhibits vitamin K reductase, resulting in depletion of the reduced form of vitamin K (vitamin KH2). As vitamin K is a cofactor for the carboxylation of glutamate residues on the N-terminal regions of vitamin K-dependent proteins, this limits the gamma-carboxylation and subsequent activation of the vitamin K-dependent coagulant proteins.
