WarfarinAnticoagulant: Anticoagulants are a class of drugs that work to prevent the coagulation (clotting) of blood. Such substances occur naturally in leeches and blood-sucking insects.Prothrombin time: The prothrombin time (PT) — along with its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) — are assays evaluating the extrinsic pathway of coagulation. This test is also called "ProTime INR" and "PT/INR".Pulmonary hemorrhageFamilial atrial fibrillation: Familial atrial fibrillation is an autosomal dominant heart condition that causes disruptions in the heart's normal rhythm. This condition is characterized by uncoordinated electrical activity in the heart's upper chambers (the atria), which causes the heartbeat to become fast and irregular.Clavaminate synthase: Clavaminate synthase (, clavaminate synthase 2, clavaminic acid synthase) is an enzyme with system name deoxyamidinoproclavaminate,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating). This enzyme catalyses the following chemical reactionVitamin K reactionRodenticide: Rodenticides, colloquially rat poison, are typically non-specific pest control chemicals made and sold for the purpose of killing rodents.Pharmacogenetics: Pharmacogenetics is the study of inherited genetic differences in drug metabolic pathways which can affect individual responses to drugs, both in terms of therapeutic effect as well as adverse effects. The term pharmacogenetics is often used interchangeably with the term pharmacogenomics which also investigates the role of acquired and inherited genetic differences in relation to drug response and drug behavior through a systematic examination of genes, gene products, and inter- and intra-individual variation in gene expression and function.List of kanji by stroke count: This Kanji index method groups together the kanji that are written with the same number of strokes. Currently, there are 2,186 individual kanji listed.PhylloquinoneAspirinDrug interaction: A drug interaction is a situation in which a substance (usually another drug) affects the activity of a drug when both are administered together. This action can be synergistic (when the drug's effect is increased) or antagonistic (when the drug's effect is decreased) or a new effect can be produced that neither produces on its own.Intracranial hemorrhageClemizoleCoagulation testing: Blood clotting tests are the tests used for diagnostics of the hemostasis system.Arterial embolismOsmotic controlled-release oral delivery system: OROS (Osmotic [Controlled] Release Oral [Delivery] System) is a controlled release oral drug delivery system in the form of a tablet. The tablet has a rigid water-permeable jacket with one or more laser drilled small holes.Superficial vein thrombosis: Superficial vein thrombosis (SVT) is a type of venous thrombosis, or a blood clot in a vein, which forms in a superficial vein near the surface of the body. Usually there is an inflammatory reaction around the vein which presents as a painful induration with erythema.Gamma-glutamyl carboxylase: Gamma-glutamyl carboxylase is an enzyme that in humans is encoded by the GGCX gene, located on chromosome 2 at 2p12.ScillirosideAntiplatelet drug: An antiplatelet drug (antiaggregant) is a member of a class of pharmaceuticals that decrease platelet aggregation and inhibit thrombus formation. They are effective in the arterial circulation, where anticoagulants have little effect.ThrombusPhlegmasia cerulea dolens: Phlegmasia cerulea dolens (literally: painful blue edema) is an uncommon severe form of deep venous thrombosis which results from extensive thrombotic occlusion (blockage by a thrombus) of the major and the collateral veins of an extremity. It is characterized by sudden severe pain, swelling, cyanosis and edema of the affected limb.Vitamin K deficiencyConcentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased. In simple terms, the higher the concentration of gas administered, the faster the alveolar concentration of that gas approaches the inspired concentration.PhenylbutazoneMineral salts pyridone broth: Mineral salts pyridone broth is a selective medium for bacteria that can metabolize pyridone (which is an unusual carbon source that a select few types of bacteria can use). This medium is used to isolate bacteria belonging to the Arthrobacter genus among other bacteria genera.Low molecular weight heparin: In medicine, low-molecular-weight heparin (LMWH) is a class of anticoagulant medications. They are used in the prevention and treatment of venous thromboembolism (deep vein thrombosis and pulmonary embolism) and in the treatment of myocardial infarction.
