No such thing as Big Pharma. If one company can bring a drug that will run its competitors out of the market they will. If another company can make something similar, they will claim their version is superior and try to take all the business from the first company.
No different than Big Electronics or Big Deodorent.
Big Electronics is always coming up with shocking current innovations that charge the economy, but Big Deodorant is just the pits.
You incorrectly assume each Pharma has control over their product availability. The FDA is in control, and the FDA has a long record of burying good products. The really big Pharma control the FDA.
Unfortunately, scientists have cures for many problems in mice. In 2008, there was a Canadian study which found the following:
Diabetic mice became healthy virtually overnight after researchers injected a substance to counteract the effect of malfunctioning pain neurons in the pancreas. "I couldn't believe it," said Dr. Michael Salter, a pain expert at the Hospital for Sick Children and one of the scientists. "Mice with diabetes suddenly didn't have diabetes any more."
They injected the neuropeptide "substance P" in the pancreases of diabetic mice, a demanding task given the tiny size of the rodent organs. The results were dramatic. The islet inflammation cleared up and the diabetes was gone. Some have remained in that state for as long as four months, with just one injection.
