The Impact of a Drug Safety Warning on Discussions between Doctors and Their Patients; the Case
of Rosiglitazone
By 2011, Europe, the UK, India, New Zealand and South Africa had all banned the use
of rosiglitazone, although the FDA continued to allow its sales in the United States.
«It's not a pure randomly assigned trial
of rosiglitazone versus a different drug,» Bach says.
Differential Effects
of Rosiglitazone on Skeletal Muscle and Liver Insulin Resistance in A - ZIP / F - 1 Fatless Mice
Combined effects
of rosiglitazone and conjugated linoleic acid on adiposity, insulin sensitivity, and hepatic steatosis in high - fat - fed mice.
«Previous studies had tested the use
of rosiglitazone for cancer treatment, but the outcome was not encouraging.
The team found that the white wines had low binding affinities, but all the reds bound readily: the tendency of 100 millilitres of red wine — about half a glass — to bind to PPAR - gamma is up to four times as strong as the same tendency in the daily dose
of rosiglitazone (Food and Function, DOI: 10.1039 / c0fo00086h).

They also showed that they could manipulate Klotho expression pharmacologically using the anti-diabetic drug
rosiglitazone, which resulted in decreased levels
of Wnt5A.
Klotho is a secreted protein that can be measured in the serum
of patients and this can help in determining which patients would benefit from
rosiglitazone therapy and would be eligible for further studies.
The researchers showed that a two - day treatment regimen with partial or selective PPAR - γ agonists (Telmisartan and
Rosiglitazone — both FDA - approved drugs) ameliorated the pathological outcomes
of infection in mice by inducing expression
of glucose transporters.
Clinical trials
of GlaxoSmithKline's diabetes drug Avandia (
rosiglitazone) and Merck's anti-inflammatory Vioxx (rofecoxib) revealed an elevated cardiac risk from the drugs, but relevant findings were held back from regulators or never published.
Prolonged decrease
of adipocyte size after
rosiglitazone treatment in high - and low - fat - fed rats.
When BubR1H / H; INK - ATTAC mouse bone marrow cells were pushed into senescence in vitro by the PPAR - γ - activating drug
rosiglitazone, a subpopulation
of the cells exhibited high levels
of INK - ATTAC expression and GFP, coupled with SAβ - gal staining; subsequent to treatment with the INK - ATTAC activating drug, these cells rapidly entered into apoptosis, and within 48 h were either destroyed or in the cell death process.
Taking either
rosiglitazone or Lovaza with metformin seemed to mitigate some
of the negative heart effects
of metformin alone in men.
But women, already benefiting from metformin, improved heart metabolism further by adding
rosiglitazone, with the desired effect
of reducing the heart's dependence on fat metabolism.
Under McGill's supervision, the first group received metformin alone; the second received metformin plus
rosiglitazone (Avandia); and the third received metformin plus Lovaza, which is a kind
of fish oil.
The diabetes drug
rosiglitazone has been under intense scrutiny since a 2007 study in the New England Journal
of Medicine looked at more than 40 clinical trials and linked the drug's use with increased risk
of heart attack and death from heart disease.
Metformin is also sold under the brand names Glucophage and Glucophage XR, and is found in pills that combine two types
of antidiabetes medication, such as Glucovance and Metaglip (which combine metformin with a sulfonylurea drug) and Avandamet (a combination
of metformin and
rosiglitazone, a thiazolidinedione medication).
Pills to control blood sugar in people who have diabetes — like Avandia (
rosiglitazone) or Actos (pioglitazone)-- make it harder to get sodium out
of the body, which leads to swelling.
One big review
of 14 studies found that berberine extracts are equally as effective at lowering insulin as the common diabetes drugs metformin, glipizide, and
rosiglitazone.
Furthermore, the best part is that the study is just one among dozens; a large review
of 14 studies found that berberine is as effective as pharmaceutical oral diabetes drugs such as glipizide, metformin and
rosiglitazone.
Avandia (
rosiglitazone) is the poster child for what is wrong with the drug treatment
of type 2 diabetes.
In the report, published in the December 2007 issue
of Nature Medicine, researchers from the Salk Institute in La Jolla, California report that
rosiglitazone (Avandia) has been shown to interfere with >> Read Article

Rosiglitazone use was associated with a 25 % higher risk
of heart attack.
Unexpectedly,
rosiglitazone increased the risk
of heart attacks.
