Class	Examples
Coumarins/4-hydroxycoumarins	First generation: warfarin, coumatetralyl Second generation: difenacoum, brodifacoum, flocoumafen and bromadiolone.
1,3-indandiones	diphacinone, chlorophacinone, pindone These are harder to group by generation. According to some sources, the indandiones are considered second generation. However, according to the U.S. Environmental Protection Agency, examples of first generation agents include chlorophacinone and diphacinone.
4-thiochromenones	Difethialone is the only member of this class of compounds.
Indirect	Sometimes, anticoagulant rodenticides are potentiated by an antibiotic or bacteriostatic agent, most commonly sulfaquinoxaline. The aim of this association is that the antibiotic suppresses intestinal symbiotic microflora, which are a source of vitamin K. Diminished production of vitamin K by the intestinal microflora contributes to the action of anticoagulants. Added vitamin D also has a synergistic effect with anticoagulants.
