NO NEED FOR ANIMAL TESTING!!!
The human body – indeed most living systems – is extremely complex.
complexity and intricacy is precisely why animals are not good models for human medicine.
Humans differ from other animals anatomically, genetically and metabolically, meaning data derived from animals cannot be extrapolated to humans with sufficient accuracy.
We all know the disasters that can be unleashed on humans, as a result of the
use of animal experiments. To list a few, such as Thalidomide, Vioxx, Opren,
Zonax, Iressa, Exanta,
Celebrex, Torcetrapib, Prexige etc., is to tell a frightening and harrowing story of human suffering.
Surprisingly, despite the obvious lessons, the methodology is still used.
And The other side of animal experimentation is that potentially valuable medicines can be
overlooked, because of this same species difference. Penicillin, for instance,
would never have been allowed past the first animal tests, had it been tested on
Even the US Federal Drug Administration confirms that nine out of ten drugs ‘proven’ successful in animal tests fail in human trials. This not only questions the efficacy and the fundamental argument for using animals, but critically raises the question about all the drugs that failed in animals which might have worked in humans. How many discarded cures for cancer?
But if we can’t test on animals what can we we test on? we now have scientific (not fiction) technologies such as microfluidic chips and microdosing. Not only do these techniques analyse the effects of drugs on an entire living system, they analyze a human living system, eliminating error caused by species differences and resulting in data that is relevant to humans.
