Anisindione is a synthetic indanedione anticoagulant. Anisindione interferes with the vitamin K-dependent hepatic synthesis of active clotting factors by inhibiting the reduction of vitamin K. This leads to an inhibition of gamma-carboxylation of glutamic acid residues to gamma-carboxyglutamic acid in clotting factors II, VII, IX and X. The consequential effects of this inhibition include a reduced activity of these clotting factors and prolonged blood clotting time.

Anticoagulants are indicated for prophylaxis and/or treatment of venous (or arterial /Not included in US product labeling/) thrombosis (and its extension) and pulmonary embolism, deep vein thrombosis (DVP) or pulmonary embolism (treatment). Oral anticoagulatns are used during and following initial heparin therapy to decrease the risk of extension, recurrence, or death. /Anticoagulants; Included in US product labeling/

4.2 Drug Warning

Serious, sometimes fatal, toxic reactions were reported occasionally in patients receiving phenindione (no longer commercially available in US), and the possibility of these reactions should be considered in patients receiving anisindione. Adverse effects reported with phenindione (no longer commercially available in US) include dermatologic reactions such as such as urticaria and rash (usually erythematous and macular), which sometimes progressed to exfoliative dermatitis; nephrotic reactions, including anuria and albuminuria with massive edema and tubular necrosis; hepatotoxicity manifested by hepatitis and jaundice; and hematologic reactions manifested by eosinophilia, agranulocytosis or leukopenia (resulting from either maturation arrest or granulocytic hypoplasia), leukocytosis, anemia, thrombecytopenia, atypical mononuclear cells, the presence of leukocyte agglutinins, agranulocytosis, aplastic anemia, and red cell aplasia. In addition, hemorrhagic infarction and necrosis of the skin, alopecia, steatorrhea, sore throat and mouth, parlysis of accommodation and blurred vision, diarrhea, nausea, fever, malaise, and headache have been reported in patients receiving the drug.

In patients with alkaline urine, the urine may be red-orange during therapy with anisindione and patients should be informed of this possibility.

The only consistently reported adverse nonhemorrhagic effect of anisindione is dermatitis. However, agranulocytosis and hepatitis also have been reported with the use of this drug.

5 Pharmacology and Biochemistry
5.1 Pharmacology

Anisindione is a synthetic anticoagulant and an indanedione derivative. It is prescribed only if you cannot take coumarin-type anticoagulants such as coumadin as anisindione is a powerful drug with serious potential side effects. Anticoagulants decrease the clotting ability of the blood and therefore help to prevent harmful clots from forming in the blood vessels. These medicines are sometimes called blood thinners, although they do not actually thin the blood. They also will not dissolve clots that already have formed, but they may prevent the clots from becoming larger and causing more serious problems.

5.4 Mechanism of Action

Like phenindione, to which it is related chemically, anisindione exercises its therapeutic action by reducing the prothrombin activity of the blood. By inhibiting the vitamin K–mediated gamma-carboxylation of precursor proteins, the formation of active procoagulation factors II, VII, IX, and X, as well as the anticoagulant proteins C and S is prevented. Anisindione has no direct thrombolytic effect and does not reverse ischemic tissue damage, although it may limit extension of existing thrombi and prevent secondary thromboembolic complications.


Oral anticoagulants have no direct effect on circulating clotting factors. Instead they block hepatic formation of factors II, VII, IX, and X by competitively inhibiting action of vitamin K. Synthesis of these factors is dependent upon sufficient supply of vitamin.

Goodman, L.S., and A. Gilman. (eds.) The Pharmacological Basis of Therapeutics. 5th ed. New York: Macmillan Publishing Co., Inc., 1975., p. 1356


The oral anticoagulants block the regeneration of reduced vitamin K and thereby induce a state of functional vitamin K deficiency. The mechanism of the inhibition of reductase(s) by the coumarin drugs is not known. There exist reductases that are less sensitive to these drugs but that act only at relatively high concentrations of oxidized vitamin K; this property may explain the observation that administration of sufficient vitamin K can counteract even large doses of oral anticoagulants. /Oral Anticoagulants/

Hardman, J.G., L.E. Limbird, P.B., A.G. Gilman. Goodman and Gilman's The Pharmacological Basis of Therapeutics. 10th ed. New York, NY: McGraw-Hill, 2001., p. 1527


Both 4-hydroxycoumarin derivatives and indandiones (also known as oral anticoagulants) are antagonists of vitamin K. Their use as rodenticides is based on the inhibition of the vitamin K-dependent step in the synthesis of a number of blood coagulation factors. The vitamin K-dependent proteins ...in the coagulation cascade... are the procoagulant factors II (prothrombin), VII (proconvertin), IX (Christmas factor) and X (Stuart-Prower factor), and the coagulation-inhibiting proteins C and S. All these proteins are synthesized in the liver. Before they are released into the circulation the various precursor proteins undergo substantial (intracellular) post-translational modification. Vitamin K functions as a co-enzyme in one of these modifications, namely the carboxylation at well-defined positions of 10-12 glutamate residues into gamma-carboxyglutamate (Gla). The presence of these Gla residues is essential for the procoagulant activity of the various coagulations factors. Vitamin K hydroquinone (KH2) is the active co-enzyme, and its oxidation to vitamin K 2,3-epoxide (KO) provides the energy required for the carboxylation reaction. The epoxide is than recycled in two reduction steps mediated by the enzyme KO reductase... . The latter enzyme is the target enzyme for coumarin anticoagulants. Their blocking of the KO reductase leads to a rapid exhaustion of the supply of KH2, and thus to an effective prevention of the formation of Gla residues. This leads to an accumulation of non-carboxylated coagulation factor precursors in the liver. In some cases these precursors are processed further without being carboxylated, and (depending on the species) may appear in the circulation. At that stage the under-carboxylated proteins are designated as descarboxy coagulation factors. Normal coagulation factors circulate in the form of zymogens, which can only participate in the coagulation cascade after being activated by limited proteolytic degradation. Descarboxy coagulation factors have no procoagulant activity (i.e. they cannot be activated) and neither they can be converted into the active zymogens by vitamin K action. Whereas in anticoagulated humans high levels of circulating descarboxy coagulation factors are detectable, these levels are negligible in warfarin-treated rats and mice. /Anticoagulant rodenticides/
