The most common used LD50 test involves seeing which chemical kills 50% of the animals being used in the experiment. Drugs for the animal test are not safe for the animals. The 1950 sleeping pill which caused 10,000 babies to be born with birth effects, was tested on animals prior to its commercial release. Animal tests on the drug Vioxx showed that it had a protective effort on mice heart, yet it caused 27,000 heart attacks before being pulled from the market.
Animal testing may mislead researchers into ignoring potential, cures, and treatments. A report on slate.com stated that a "source of human suffering may be the dozens of promising drugs that get shelved when they cause problems in animals that may not be relevant for humans." Intravenous vitamin C has shown to be affecting humans sepsis.
" In conclusion, animal testing should be eliminated because it violates animals' rights, it causes pain and suffering to the experimental animals, and other means of testing product toxicity are available.” So what do you think should animal testing still be going on. Over 100 million animals are burned, crippled, poisoned, and abused in US labs every year. According to the Humane Society, registration of a single pesticide requires more than 50 experiments and the use of as many as 12,000 animals. Even animals that are protected under the AWA can be abused and tortured. And the law doesn’t require the use of valid alternatives to animals, even if they are available. The harmful use of animals in experiments is not only cruel but also often ineffective.
Out of 48 cancer drugs approved by the European Medicines Agency from 2009 to 2013 to treat 68 types of cancer, almost half showed no survival benefits according to a recent study. Even in cases where benefits were seen, the difference was judged to be ‘clinically insignificant’. A recent drug trial in France resulted in the death of one volunteer and left four others severely brain-damaged in 2016. The drug, which was intended to treat a wide range of conditions including anxiety and Parkinson’s disease, was tested in four different species of animals (mice, rats, dogs, and monkeys) before being given to humans. Out of 93 dangerous drug side effects, only 19% could have been predicted by animal tests, a recent study found.
