antidiabetes drugs (either rosiglitazone or pioglitazone) had a 28% lower
incidence of Parkinson's disease than people taking other treatments for
diabetes who had never taken glitazones ... Glitazones are a class of drug that
activate the peroxisome proliferation-activated gamma (PPARγ) receptor, which is
found inside cells in many different body organs. PPARγ activation by glitazones
leads to reduced insulin resistance, which has been useful for treating people
with diabetes, but the receptor has many other functions that have not been
studied as thoroughly in humans"

"Treatment with pioglitazone showed a remarkable side benefit. It was able to
significantly decrease the risk of dementia ... The longer the treatment, the
lower the risk ... Risk reduction was most noticeable when the drug was
administered for at least two years ... Metformin -- another frequently
prescribed antidiabetic drug -- also lowered the risk of developing dementia.
However, the effect was lower than that of pioglitazone" - See

Some Diabetes Drugs May Affect Cancer Risk in Women - WebMD, 12/6/13 -
"Cleveland Clinic researchers analyzed data from more
than 25,600 women and men with type 2 diabetes ... The drugs included "insulin
sensitizers," which lower blood sugar and insulin levels in the body by
increasing the muscle, fat and liver's response to insulin. The other drugs
analyzed were "insulin secretagogues," which lower blood sugar by stimulating
beta cells in the pancreas to make more insulin ... The use of insulin
sensitizers in women was associated with a 21 percent decreased cancer risk
compared to insulin secretagogues, the investigators found. Furthermore, the use
of a specific insulin sensitizer called thiazolidinedione was associated with a
32 percent decreased cancer risk in women compared to sulphonylurea, an insulin
secretagogue ... there were no significant differences between men who used
insulin sensitizers or secretagogues"

Board (DTAB) there. The DTAB met July 19 and recommended that pioglitazone be
put back on the market in India, albeit with a boxed warning about bladder
cancer ... The Government may or may not accept its advice ... There were
accusations in some of the media coverage that the motivation behind this
correspondence was the fact that Dr. Mohan had received funding from Merck,
Sharpe & Dohme, the Indian subsidiary of Merck & Co, whose newer diabetes drug
sitagliptin (Januvia) stands to gain if pioglitazone is unavailable ... The same
report adds that another Chennai-based diabetes doctor, Vijayam Balaji, MD, from

Diabetes
drug improves memory, study suggests - Science Daily, 11/21/12 -
"treatment with the anti-insulin-resistance drug
rosiglitazone enhanced learning and memory as well as normalized insulin
resistance. The scientists believe that the drug produced the response by
reducing the negative influence of Alzheimer's on the behavior of a key

increases the risk of heart disease. Pioglitazone is in the same class of drugs
but they claim that increases the chances of bladder cancer. Personally I don't
have diabetes but I take low dose metformin and pioglitazone. See my

Brain
insulin resistance contributes to cognitive decline in Alzheimer's disease -
Science Daily, 3/23/12 - "This is the first study to
directly demonstrate that insulin resistance occurs in the brains of people with
Alzheimer's disease ... Our research clearly shows that the brain's ability to
respond to insulin, which is important for normal brain function, is going
offline at some point ... We believe that brain insulin resistance may be an
important contributor to the cognitive decline associated with Alzheimer's
disease ... The risk of developing Alzheimer's disease is increased by 50
percent in people with diabetes ... insulin resistance of the brain occurs in
Alzheimer's disease independent of whether someone has diabetes ... The
investigators used samples of postmortem brain tissue from non-diabetics who had
died with Alzheimer's disease, stimulated the tissue with insulin, and measured
how much the insulin activated various proteins in the insulin-signaling
pathways ... three insulin-sensitizing medicines are already approved by the FDA
for treatment of diabetes. These drugs readily cross the blood-brain barrier and
may have therapeutic potential to correct insulin resistance in Alzheimer's
disease and MCI" - Note: I suspected this for a long time. It doesn't
say what those three drugs are but I'm guessing metformin and Actos are two of
them. I don't have diabetes but I take low doses of both. My doc says I'm
crazy.

Pioglitazone: A Key Component for Type 2 Diabetes Therapy - Medscape,
10/5/11 - "Even in patients who do not already have
known CV disease there is an increasingly strong case developing in favour of
using the combination of metformin, pioglitazone and a GLP-1 agonist in the
modern management of type 2 diabetes.[42] This case is argued by Professor Ralph
DeFronzo who, in print[42] as well as in a webcast,[43] describes an 'ominous
octet' of factors combining in the pathophysiology of type 2 diabetes (figure
4). With regard to these eight factors he points out that sulphonylureas only
improve insulin secretion and that even this effect is transient. By contrast,
GLP-1 agonists impact on five members of the ominous octet, pioglitazone on four
and metformin on two, and that the effects of these agents are complementary and
some at least are sustained. As a potent insulin sensitiser, pioglitazone
reduces hepatic glucose output and increases glucose uptake in muscle. It
improves and preserves pancreatic beta-cell function and therefore insulin
secretion and it is also a potent inhibitor of lipolysis. At the level of the
liver, metformin is a potent insulin sensitiser reducing hepatic gluconeogenesis
and in muscle it provides an additive effect to pioglitazone in promoting
glucose uptake. GLP-1 analogues increase the incretin effect, increasing insulin
secretion, reducing glucagon secretion and hepatic glucose output. Finally GLP-1
agonists act on the brain reducing appetite and promoting weight loss.
DeFronzo[42,43] reminds us that even at the stage of impaired glucose tolerance,
individuals have lost >80% of their beta-cell function. Therefore he argues that
the modern paradigm for the management of type 2 diabetes would involve
intensive management at the earliest stages using metformin, pioglitazone and
GLP-1 agonists in combination with a view to achieving a target HbA1C
<6%.[42,43] It is worth noting in particular that the combination of these
agents does not require expensive home glucose monitoring and these agents are
not associated with a risk of hypoglycaemia"

System
in brain -- target of class of diabetes drugs -- linked to weight gain -
Science Daily. 5/1/11 - "PPAR-γ is the target of a class
of diabetes drugs called TZDs (thiazolidinediones). This class of drugs reduces
blood glucose levels but also causes considerable weight gain ... Seeley and his
team set out to determine whether or not the brain's PPAR-γ system was
responsible for the weight gain associated with TZDs ... by giving TZD drugs in
the same manner that people take them, rats gained weight. This was because the
drugs activated PPAR-γ in the brain. Thus, weight gain associated with this
class of drugs may not be a result of action of PPAR-γ in fat as had been
previously thought, but rather a result of a change in activity in parts of the
brain known to regulate appetite ... If you artificially turn on PPAR-γ, you can
increase food intake in rats ... If you block these receptors in animals on
high-fat diets that make animals obese, animals gain less weight ... In the
past, says Seeley, people thought that the production of more fat cells in
response to TZD drugs was the cause of the resulting weight gain, but he adds,
"Just having more fat cells is not enough to make animals or people fatter.
Rather you have to eat more calories than you burn and that is exactly what
happens when you turn on the brain PPAR-γ system"

Obesity and Fatty Liver disease - MedicineNet.com -
"Doctors also are using medications to treat non alcoholic fatty liver disease.
For example, insulin-sensitizing agents, such as the thiazolidinediones,

only help to control blood glucose in patients with diabetes, but they also
improve enzyme levels in patients with non alcoholic fatty liver disease"

Pioglitazone Shows Promise for Oral Cancer Prevention - Medscape, 3/23/11 -
"In a phase 2 clinical trial, the thiazolidinedione
pioglitazone partially or completely eliminated two thirds of leukoplakia

Pharmaceuticals) "works pretty well — better than anything we've seen before
...Leukoplakia lesions, which are usually caused by irritation, appear on the
tongue or sometimes on the insides of the cheek. About 17% of the lesions become
invasive cancer, and no treatment has been shown to reliably prevent this ...
The researchers randomly divided these patients so that 22 patients received
pioglitazone 45 mg daily for 12 weeks and 22 patients served as a comparison
group ...15 of the 22 patients in the pioglitazone group had a clinical and/or
histologic response; they did not detect any change in the comparison group ...
In the pioglitazone group, the lesions completely disappeared in 3 patients and
partially disappeared in 12 patients, the epithelium completely returned to
normal in 1 patient, and the dysplasia or hyperplasia reverted from advanced to
early, or from early to normal, in 6 patients ... Because it is a diabetes drug,
researchers checked the subjects' glucose levels, but they found no change,
apparently because pioglitazone only affects glucose in diabetics"

Drug
prevents Type 2 diabetes in majority of high-risk individuals - Science
Daily, 3/23/11 - "A pill taken once a day in the morning
prevented type 2 diabetes in more than 70 percent of individuals whose obesity,
ethnicity and other markers put them at highest risk for the disease ... The
team also noted a 31 percent decrease in the rate of thickening of the carotid
artery, the major vessel that supplies blood to the brain ... The 72 percent
reduction is the largest decrease in the conversion rate of pre-diabetes to
diabetes that has ever been demonstrated by any intervention, be it diet,
exercise or medication ... pioglitazone, which is marketed as Actos® ... It is
the most efficacious method we have studied to date to delay or prevent the
onset of type 2 diabetes ... This particular medication does two things --
improves insulin resistance and improves beta cell function, which are the two
core defects of diabetes" - Note: Like I've said before, my doc says I'm
crazy but I've been taking pioglitazone for anti-aging for some time. Something
that’s discerning is when someone asks why I look young and I mention various

in fasting insulin and blood glucose levels, glycated hemoglobin (HbA1C),
C-reactive protein (CRP), and triglycerides as well as improved HDL-cholesterol
levels ... the post hoc analysis "ties nicely" with the 2006 CHICAGOstudy, in

Molecular 'switch' contributes to cellular aging process: Discovery suggests new
treatments for metabolic diseases - Science Daily, 11/30/10 -
"in older animals SMRT acts like a "switch," turning off
the protective cellular activities of proteins known as peroxisome
proliferator-activated receptors (PPARs). PPARs help regulate genes that promote
fat burning to maintain lipid (blood fat) balance and reduce oxidative stress.
The researchers were able to reduce the negative effects of oxidative stress by
giving antioxidants or drugs known to turn the protective activities of PPARs
back on ... PPAR drugs have been used to increase insulin sensitivity and lower
blood lipid levels ... we believe SMRT is one of the key players that causes
age-dependent decline in mitochondrial function by blocking PPAR activity, and
we've found a way to boost the body's ability to better handle metabolic and

Study
compares risk with 2 diabetes drugs - Science Daily, 8/24/10 -
"risks of heart disease events and death were no
different between patients who took the diabetes drugs rosiglitazone or
pioglitazone. In this analysis, approximately 4 percent of patients taking
either drug -- sold as Avandia and Actos -- suffered a heart attack, heart
failure, both or died over a 33-month period ... Besides its findings that
rosiglitazone and pioglitazone have comparable risks, what distinguishes this
latest study from other claims-based analyses is its analysis of death records,
which include out-of-hospital deaths ... study also followed patients for a
longer period of time than some of the earlier research" - So the two
drugs have equal risks but what's confusing is how does that 4% risk compare to
a placebo?

Pioglitazone
attenuates prostatic enlargement in diet-induced insulin-resistant rats by
altering lipid distribution and hyperinsulinemia - Br J Pharmacol. 2010 Aug
19 - "Increased incidence of benign prostatic
hyperplasia among insulin-resistant individuals suggest a role for
hyperinsulinemia in prostatic enlargement ... High fat diet led to the
accumulation of fat in non-adipose tissues, insulin resistance, compensatory
hyperinsulinemia and prostatic enlargement in rats. Pioglitazone treatment
altered fat distribution, improved insulin-sensitivity and normalized lipid and
insulin level in rats on the high-fat diet. The improved metabolic parameters
led to decreased cellular proliferation and increased apoptosis in the prostate
gland. High-fat diet feeding and pioglitazone treatment did not change plasma
testosterone levels. However, significant prostatic atrophy was observed in
castrated, rats irrespective of dietary intervention"

Metformin vs. Sulfonylureas for Diabetes - WebMD, 12/4/09 -
"Researchers reported that diabetes patients who used
sulfonylureas had a higher risk of death from all causes and a higher risk of
heart failure than diabetes patients who used the most widely prescribed
diabetes drug, metformin ... Compared with metformin, also known as Glucophage,
single-drug treatment with first- and second-generation sulfonylureas was
associated with up to a 61% increased risk for death. Users of second-generation
sulfonylureas had up to a 30% higher risk for congestive heart failure ...
Patients treated with Actos or Avandia did not appear to have a greater risk for
heart attacks than those treated with metformin"

Diabetes
Drug Shows Promise In Fighting Lethal Cancer Complication - Science Daily,
9/24/09 - "in an animal study, a diabetes drug that
promotes insulin sensitivity slowed the progression of muscle wasting and fat
loss, the main consequences of a syndrome called cachexia ... Research suggests
that cachexia is responsible for between one-fifth and one-third of all cancer
deaths ... These data provide evidence that in mice with colon cancer tumors,
insulin resistance may be involved in the development of cachexia rather than
occur as a result of cachexia ... Within eight days, the mice with cancer
receiving the rosiglitazone showed more sensitivity to insulin than did the mice
with tumors that received no medication. The insulin sensitivity of the
medicated mice matched that of mice without tumors ... In addition to stopping
fat and muscle loss, the rosiglitazone also dramatically reduced two biological
markers present when proteins break down, particularly in muscles, and a third
marker that indicates cells are eating their own amino acids in an attempt to
survive" - Note: I don't know why they did this study with
rosiglitazone. That's the one that may be connected to heart disease.
Pioglitazone is the same class of drug and is not connected to heart disease. I
take it for anti-aging also. See my Insulin

hippocampal subfields of the transgenic mice and this decrease was prevented by
rosiglitazone. In parallel with behavioural studies, rosiglitazone also
normalized GR levels in older animals. This effect may contribute to explain the

Why
Certain Diabetes Drugs Appear To Lower Blood Pressure - Science Daily,
3/4/08 - "Drugs called thiazolidinediones (TDZs), which
are used to treat type II diabetes, target and activate PPAR gamma. In addition
to controlling blood sugar, these drugs also appear to lower blood pressure ...
It appears that when PPAR gamma is activated it initiates a cascade of events
that protect the blood vessel ... When we interfere with the PPAR gamma pathway,
those protective mechanisms are eliminated and the blood vessel becomes
dysfunctional" - I've read all the negative of thiazolidinediones (TDZs)
and I still feel the good outweigh the bad. I take Actos (pioglitazone HCl) to

Comparative effects of rosiglitazone and pioglitazone on fasting and

diabetes - Expert Opin Pharmacother. 2008 Feb;9(3):343-9 -
"HbA1c, insulin sensitivity (as assessed by the
homeostasis model assessment) and LDL size and subclasses did not differ before
treatments. Rosiglitazone and pioglitazone resulted in a similar improvement in
HbA1c and insulin sensitivity. Fasting total cholesterol increased more after
rosiglitazone compared with pioglitazone (p = 0.04), whereas triglycerides
decreased after pioglitazone and increased after rosiglitazone ... Pioglitazone

Clinical trials with thiazolidinediones in subjects with Type 2 diabetes--is
pioglitazone any different from rosiglitazone? - Expert Opin Pharmacother.
2008 Feb;9(3):405-20 - "these agents have markedly
different effects on lipids. Rosiglitazone increases total, low- and
high-density lipoprotein (LDL and HDL) cholesterol, and triglycerides, whereas
pioglitazone has no effect on total or LDL cholesterol, increases HDL
cholesterol and decreases triglycerides. Both rosiglitazone and pioglitazone
decrease inflammatory markers. Furthermore, both rosiglitazone and pioglitazone
may cause a small decrease in blood pressure, improve endothelial function and
reduce restenosis. Microalbuminuria is also reduced by both rosiglitazone and
pioglitazone. Despite the improvements in surrogate end points, there is little
clear evidence that either rosiglitazone or pioglitazone cause major
improvements in cardiovascular outcomes. Thus, rosiglitazone has no effect or
may even increase cardiovascular outcomes, whereas, in high-risk subjects,
pioglitazone has a marginal ability to decrease cardiovascular outcomes"

Pioglitazone
(Actos) and bladder cancer: legal system triumphs over the evidence - J
Diabetes Complications. 2016 Apr 11 - "In preclinical studies, pioglitazone was
associated with bladder cancer in male rats (but not in female rats, mice dogs
or monkeys). Because of this association, the Federal Drug Administration
requested a large 10year epidemiological study to evaluate whether there was an
association between bladder cancer and exposure to pioglitazone in patients ...
Of the 23 epidemiological studies that have been published to date, 18 showed no
association between bladder cancer and pioglitazone (5 with a combination of
rosiglitazone and pioglitazone). Of the five that did show a significant
association with pioglitazone, three could not be confirmed in the same
population and in one of them there were significantly more risk factors for
bladder cancer in the patients exposed to pioglitazone. In the fourth one, a
significant association became non-significant when patients >79years were
included. In the fifth one, detection bias was a major flaw. Currently, >11,000
legal cases have been filed, many of which claim emotional distress due to the
fear of bladder cancer. To limit their legal costs, the pharmaceutical company
has established a 2.4 billion dollar settlement pool. So much for evidence-based
medicine"

Thiazolidenediones induce tumour-cell apoptosis through the Akt-GSK3β pathway
- J Clin Pharm Ther. 2011 Mar 16 - "Prostate cancer is a
major health threat for men. Thiazolidenediones (TZDs) are synthetic ligands of
the peroxisome proliferator-activated receptor γ (PPARγ), and previous studies
have shown that TZDs induce apoptosis of prostate cancer cells independently of
PPARγ activation. However, the exact mechanism of these effects remains unknown
... The apoptosis-inducing effect of TZDs on prostate cancer cells involves the
inhibition of Akt phosphorylation. Furthermore, TZDs induce inactivation of
GSK3β, a multifunctional kinase that mediates essential events promoting
prostate cancer development and acquisition of androgen independence. In
addition, the GSK3β inhibitor lithium chloride sensitizes prostate cancer cells
to TZDs cytotoxicity. What is new and Conclusion: Our data suggest that
modulation of Akt-GSK3β pathway is involved in the cell death pathway engaged by
TZDs in prostate cancer cells. This reveals another possible mechanism of TZDs
on apoptosis in prostate cancer. Inhibition of the Akt-GSK3β cascade may be a
useful approach in prostate cancer" - Got that because I'm going to give
a test on it in next weeks newsletter. The point is that TZDs such as
pioglitazone may help prevent or slow prostate cancer.

Pioglitazone
activates aortic telomerase and prevents stress-induced endothelial apoptosis
- Atherosclerosis. 2011 Feb 17 - "Telomeres and
associated proteins are regulators of cellular survival, regeneration and aging.
PPAR-γ agonists may mediate vascular effects in addition to insulin sensitizing.
We therefore examined whether pioglitazone regulates vascular telomere biology
... C57/Bl6 mice were randomized to treatment with pioglitazone (20mg/kg i.p.
daily) or vehicle for 4 weeks (n=6-8 per group). Telomere repeat amplification
protocols showed a 2-fold increase of aortic telomerase activity in the
pioglitazone group. Telomere repeat-binding factor 2 protein and mRNA levels
(236%+172% of vehicle) as well as phosphorylation of protein kinase Akt (479% of
vehicle) were up-regulated. Western blots demonstrated reduced aortic expression
of senescence markers p16, cell-cycle checkpoint kinase 2 and p53. These
regulatory mechanisms were independent of acute changes of telomere length.
Similar observations were made in mononuclear cells (MNC) from these mice and in
cultivated bovine aortic endothelial cells, human MNC and endothelial progenitor
cells (EPC). Telomerase activation by pioglitazone in cultivated cells was
prevented by Akt inhibitors. To test the functional relevance of the findings,
isolated mononuclear cells (MNC) were exposed to H(2)O(2). MNC from
pioglitazone-treated mice exhibited reduced apoptosis (AnnexinV-FACS). In vivo,
lipopolysaccharide-induced aortic endothelial apoptosis was potently prevented
in pioglitazone-treated animals (hairpin oligonucleotide assay). Both,
up-regulation of telomere-regulating proteins and prevention of oxidative
stress-induced aortic apoptosis, were absent in telomerase reverse transcriptase
(TERT)-deficient mice ... The findings underscore the important role of
telomere-regulating proteins for vascular cell function and survival" -

"high-sensitivity C-reactive protein (hsCRP) ... Pioglitazone treatment for 12
weeks decreased serum hsCRP levels (0.83 [1.14] to 0.52 [0.82] mg/L, P < .001)
and improved glycemic control (fasting glucose, P < .001; glycosylated
hemoglobin, P < .001) and lipid profiles (triglyceride, P = .016; high-density
lipoprotein cholesterol, P < .001). Between responders and nonresponders to the
hsCRP-lowering effect of pioglitazone, there were significant differences in
baseline hsCRP levels and changes in the postprandial glucose and the ratio of
visceral fat thickness (VFT) to subcutaneous fat thickness (SFT) (P = .004,
.011, and .001, respectively). The percentage change in hsCRP levels after
treatment was inversely correlated with baseline hsCRP levels (r = -0.497, P <
.001) and directly correlated with the change in postprandial glucose (r =
0.251, P = .021), VFT (r = 0.246, P = .030), and VFT/SFT ratio (r = 0.276, P =

pioglitazone was affected by baseline hsCRP levels (odds ratio [OR] = 7.929, P =
.007) as well as changes in postprandial 2-hour glucose (OR = 0.716, P = .025)
and VFT/SFT ratio (OR = 0.055, P = .009). In conclusion, treatment with
pioglitazone produced an anti-inflammatory effect, decreasing serum hsCRP
levels; and a decrease in the VFT/SFT ratio was independently and most strongly
associated with the hsCRP-decreasing effect. These results suggest that
abdominal fat redistribution preferentially reflects the anti-inflammatory
benefits of pioglitazone treatment"

the pioglitazone treatment, serum free fatty acid and triglyceride levels were
decreased, and serum adiponectin levels were increased. These data indicate that
pioglitazone treatment suppresses ER stress in the liver which may explain, at

Pioglitazone Exerts Protective Effects Against Stroke in Stroke-Prone
Spontaneously Hypertensive Rats, Independently of Blood Pressure - Stroke.
2007 Sep 20 - "Our work provides the first evidence that
pioglitazone significantly protects against hypertension-induced cerebrovascular
injury and stroke by improving vascular endothelial dysfunction, inhibiting
brain inflammation, and reducing oxidative stress. These beneficial effects of
pioglitazone were independent of blood pressure or blood sugar values. Thus,
pioglitazone appears to be a potential therapeutic agent for stroke in type 2

"TZDs, acting via the peroxisome proliferator-activated
receptor-gamma, affect a number of mediators involved in the development of the
cardiovascular complications of diabetes, including lipid profiles, vascular
changes, and inflammatory mediators. TZDs decrease plasminogen activator-1 and
C-reactive protein levels. They also reduce the extent of thickening of the
carotid artery and reduce hyperplasia after coronary stent implantation.
Insulin-sensitizing therapy with TZDs is a promising intervention for patients
with diabetes at risk for adverse cardiovascular outcomes"

Metformin and pioglitazone: Effectively treating insulin resistance - Curr
Med Res Opin. 2006;22 Suppl 2:S27-37 -
"The different insulin-sensitizing mechanisms of
metformin and the thiazolidinediones are manifest in partially distinct effects
on hepatic and peripheral glucose homeostasis, and clinical studies show
improved glucose control with combination therapy. Both metformin and
thiazolidinediones may also have pancreatic beta-cell preserving properties.
Furthermore, they have different beneficial effects on several other metabolic
risk markers and risk factors for cardiovascular disease. Whereas the
thiazolidinediones (particularly pioglitazone) have greater effects on multiple
aspects of dyslipidemia, metformin has anorexigenic properties. They also have
distinct effects on levels of mediators involved in inflammation and endothelial
dysfunction, and outcome studies suggest that either pioglitazone or metformin
may reduce the risk of macrovascular events"

A fixed-dose combination of pioglitazone and metformin: A promising alternative
in metabolic control - Curr Med Res Opin. 2006;22 Suppl 2:S39-48 -
"Pioglitazone increases insulin sensitivity, while
metformin reduces hepatic gluconeogenesis and improves peripheral glucose
uptake. Both agents reduce hyperglycemia and hyperinsulinemia, and appear to
protect beta-cell function ... In randomized studies, pioglitazone and metformin
administered separately provided significantly better glycemic control than
metformin monotherapy or metformin plus gliclazide. Pioglitazone and metformin
have complimentary benefits on diabetic dyslipidemia; pioglitazone primarily
improves high-density lipoprotein cholesterol and triglyceride levels (to a
greater extent than rosiglitazone does), while metformin mainly improves total
cholesterol. Pioglitazone and metformin also modulate other atherosclerosis
biomarkers, including inflammatory mediators, coagulation thrombosis components,
and carotid intima media thickness. Together, these pleiotropic effects have the
potential to confer a reduced risk of cardiovascular disease in patients with
type 2 diabetes. Pioglitazone and metformin are well tolerated in combination,
with low rates of hypoglycemia, and the convenience of a single tablet may be
expected to aid dosing compliance"
