john e russo md replied: "I have already answered a question about rosiglitazone/Avandia. Rosiglitazone belongs to a family of drugs which reduce the body's resistance to the effects of insulin. This is a very important class of drugs for type 2 diabetics for whom insulin resistance is universally present leading to increasing production of insulin and eventually pancreatic beta cell failure and the inability to produce insulin. The first drug in this class used in the United States was troglitazone. It was withdrawn by the company for fear of lawsuits. The problem was not with the drug itself it was that physicians ignored warnings that the drug was not for everyone. The 2 remaining drugs in this class in the US are rosiglitazone and pioglitazone/Actos. It is frequently stated in the medical literature that pioglitazone increases the risk of heart failure although there is absolutely no evidence to support this claim. The study which alleges that rosiglitazone may lead to cardiovascular events such as heart attacks, strokes, and deaths has serious flaws which I will outline below. This study is of more interest to attorneys who smell money than it is to physicians. As such the Food and Drug Administration at this time has stated that they have no intention of placing warnings or restrictions on rosiglitazone. The study you are referring to was a meta-analysis. Meta-analysis are by their very definition statistically 'invalid'. They are intended to identify areas where additional study is needed - meta-analysis is never intended to generate 'hard' data, conclusions, or to become the basis for changes in medical practice. A meta-analysis sums up the results of a variety of studies. Such studies have different designs and are designed to answer different questions. It should be obvious that a summation of such data would have inherent limitations. That being said the meta-analysis was a summation of studies of short duration and studies of short duration introduce significant bias for a variety of reasons. The full effect of drugs - for benefit or harm - may take months or years and the likelihood of events is quite different in the short run as opposed to the long run. Finally - the number of events were few - too few in my opinion to lead to any conclusion. For example - 18 people on rosiglitazone as opposed to 12 people on other treatment suffered adverse events. It is true that this is a 50% increase but something which is statistically significant may not be clinically relevant. For example - a study of a drug to increase exercise tolerance in people with narrowing of the arteries in the legs found that the drug produced a statistically significant increase in exercise tolerance. In fact - however - people were able to walk only 3 additional steps. This illustrates the difference between statistics which are easily manipulated and clinically relevant data. Personally I have always preferred pioglitazone to rosiglitazone but not because I believe that the former is safer. No one on rosiglitazone should stop the drug without consulting their physician. Again - at this point this is a legal concern rather than a medical concern. Many drugs are withdrawn after such articles as companies fear lawsuits. Physicians must practice in accordance with the medical literature and not out of fear of attorneys."

"It's a complicated world. If you're not familiar with meta-analyses, it may seem that something sinister is going on"
Well that's exactly how I feel. You don't know what to do and you don't have enough information to decide yourself. Even if you did have the information, could you understand it? Look at some of the other answers to this question! I had to read them all twice to understand what they were saying. Hopefully your doctor will be informed enough to make the decision for you. It is a complicated world after all.
Here for anyone who wants to get a better idea of what meta-analasys means

Balasubas replied: "I am diabetic ( Type 2 ), and I used to take Avandia. I am happy that the doctor switched my meds long before this warning about Avandia came out. It still worries me. I feel sorry if those who take, or are still taking Avandia, get heart problems. Web MD you are nuts!!!"
Has anyone had a problem on the Accord study for diabetes? Does anyone feel very overmedicated on the Accord study for diabetes? Has anyone had problems with Avandia? New drugs and incredible increases in number and dosages seem to be causing problems.
Is your Quack Doctor. Killing you with Actos or Avandia? I have been for years trying to tell people not to use avandia or actos. Before it was because of problems with heart disease. Now it is with bone disorders.
glitazone" diabetes drugs Actos and Avandia may double or triple the risk of broken bones after a year or two of use.
The finding comes from Swiss researchers who analyzed 12 years of data on U.K. diabetes patients. They compared the 1,020 patients who suffered some kind of fracture to 3,728 matched patients who did not break any bones.
Over the course of the study, most of the patients took several diabetes drugs. But those who refilled their Actos or Avandia prescriptions eight times or more -- about 12 to 18 months of use -- had nearly twice the fracture risk of other patients.
And those who refilled their Actos or Avandia prescriptions 15 times or more -- two or more years of treatment -- nearly tripled their risk of fracture, found Christophe R. Meier, PhD, head of pharmacoepidemiology research at University Hospital Basel, Switzerland, and colleagues.
"We found a very strong signal here for higher risk of fractures in people taking glitazones," Meier tells WebMD. "Our evidence fits together nicely with animal models and clinical reports suggesting that these drugs have a detrimental effect on bone. And we did not find any increased risk for other diabetes drugs, so all together, it looks like something really is going on here."
towanda replied: "I took actos for a while. I also took the one that people were dying from-I woke up one morning and this black lady had died from liver disease. The thing no one talked about is that that same pill caused my hair to thin. That would have been nice to know too.
But you do realize that when you start taking all the meds, you are betting that the damage your liver, kidneys, etc caused by the meds will lengthen your life longer than not taking them. What's the bigger killer is the doctors that have a blase attitude about what diabetics need and the importance of getting their sugar under control. I went to a doctor for years that overpilled me and just told me I needed to go on a diet. If I could have controlled my eating more, I wouldn't have diabetes. I was given pills with no way to control my sugar. You take the pills and eat less, then your sugar is low and you can't function. I finally found a doctor and I take what I need and alter to fit what I'm eating. . .as I should have been years ago. It's oh no, you can't possibly be smart enough to do that. Please, it's my life and absolute control is necessary from the very beginning instead of all the ups and downs. Or at least give people a choice-learn and take care of yourself or just take the pills, whatever the consequences. I'm on my way to googling glizazones. Thanks. . ."
Mr. Peachy® replied: "No.
Actually, my doctor is not a quack. Just a conventionally schooled MD. Who also happens to be into some alternatives, thanks to me.
I would never, ever recommend a sulfonylurea to anyone either:
MDs have a real problem. How on earth do you get the average lazy, convenience oriented patient to do what Mr. Peachy has done?.... Research, research, research, along with plenty of trial and error. Finally, a solution!! Duhhh! Eat the foods our bodies were made to eat... natural foods. Do what our bodies were made to do.... be active and get plenty of exercise. This is not rocket science, folks. Type two diabetes can be fought. You just have to get off your butt, learn a little, and just do it. Unfortunately, the average person doesn't have the wherewithal, so doctors just give up and prescribe these dangerous drugs and the patients are too lazy to look up the pros and cons and blindly trust their doctor. More...."
When will drug companies stop watching profits and start watching safety? between avandia and vioxx thats many dead americans. Because drug companies control the FDA we have these problems.
netjr thanks for the vote of optimism but in Vioxx and likely in this one the data was falsified. They left out cardiac mortality!!!

gayconservativ replied: "Avandia, Vioxx.... what else? What else?? These men and women dedicate their careers to making the drugs that help people live better lives. If there are no "profits" where is the incentive to create?"
kprofaith replied: "Never! You are right though, the FDA IS controlled by the drug companies, and they controll most of congress too. This is why we don't have a health care system in the US, because the drug co's would lose all that fat money they are sitting on! Others lives means nothing to them, and its obvious."
netjr replied: "Millions upon millions of people take drugs and "LIVE" thanks to those "EVIL" drug companies. They spend plenty on research and development so our lives might be better; but people like you would throw them down a rat whole because of a terrible mistake."
Chainsaw replied: "A lot of people who take these are going to die without them.
It is far better to die of a heart attack that I have a higher risk for than to die from an incurable disease."
kaisergirl_1 replied: "They wont becuase the FDA is just one more corrupt institution."
elias replied: "how many hundreds of medications have been approved and not pulled off the market because of safety issues? of course they are concerned with safety. hundreds of medications never even make it to market thanks to animal testing (sorry PETA). I don't believe any medication is 100% safe all the time. even tylenol has a maximum of 4000mg, and can't be taken with alcohol. We have all these disease advocacy groups demanding a cure for everything, and yet we all rip on them when something is recalled. we can't have it both ways, with the innovation is risk. some people will have side effects, some unfortunately will die. that's the price we pay for demanding a drug for everything."
Stony replied: "Historically speaking, it has been EXTREMELY RARE for corporations to police themselves adequately without government regulation."
mjyodice replied: "Again. Drug companies invest billions of dollars into research and development. It takes between 10 and 15 years to get a drug to the public. Patents only last about 7 years. Are they not entitled to make a profit from that time and effort so that they can start on another drug and start the whole process all over again. Capitalism. It works. Try it sometime."
