Coumadin (warfarin) is the active ingredient in rat poison. That being said, Coumadin is dosed, for humans, in a manner which prevents blood clotting (especially for those at risk), and does not act as a poison at the therapeutic dosage level. (However, when rats ingest the high concentrations of warfarin in rat poison, they bleed to death, internally.)
Rat poison IS coumadin.
The chemical warfarin is a blood-thinning agent (trademark name Coumadin) also used as rat poison.
Yes, one type of rat poison, sodium warfarin, also known as Coumadin, Jantoven, Marevan, Lawarin, and Waran, is routinely prescribed as a blood thinner to patients with heart disease and other illnesses.
One example of this is Coumadin (Warfarin). This anti-coagulation drug was first developed as a rat poison. It would cause the rat to excessively bleed, thus this is how it killed them. Later they determined if they can get the dosing right, it can be used for patients who have clotting disorders.
It's the other way around. Coumadin, long-time anticoagulant medication used by humans was applied as a rat toxin. The idea was that, a medication in a dosage harmless to humans would prove fatal for rats, mostly because of comparative sizes: A dose for a 150lb human was a massive overdose for a 6oz. rat. And this worked for a while. However, rats evolved past this and now, a human-normal dose of coumadin is no longer toxic for rats. To address this we've gone on to "super-coumadin" for rats -- another anticoagulant, only this time the rat-lethal (or LD50) does is also acutely toxic to humans.
To kill the pigeons with rat poison, you will have to poison their food with the rat poison. You can poison the water that the pigeons drink and the cereals that the pigeons eat.
Black rat poison.
There is no rat poison in toothpaste. Never.
Barium is used for rat poison.
No, it could not, because the poison was specifically designed to kill rats, and was developed as a rat poison/killer, not a human poison/killer. It would still be considered rat poison, even if the human died from the rat poison.
Because it's rat posion
No. Coumadin is a fancy medical name for a sophisticated medication used in heart disease treatment. In more powerful form it is also sold as a rat poison under the brand name WARFARIN.Coumadin is a brand name. Warfarin is the generic. All dose strengths of one are available in the other, thus "in more powerful form it is also sold as a rat poison under the brand name WARFARIN." Coumadin is used as a powerful anticoagulant for much more than "heart disease treatment" - for example pulmonary emboli and deep vein thromboses.
