I feel that Micardis
(telmisartan) (ARBs) with Altace (ramipril) (an
ACE inhibitor, if two drugs
are required), are the way to go for the least side effects. I'm not a doctor,
just someone that's done a lot of reading and experimenting with different blood
pressure medications. Consult your doctor before taking any supplement or
medication. See:

blood pressure pills linked to cancer - MSNBC, 6/13/10 -
"experts found a link between people taking
medicines known as angiotensin-receptor blockers ... one extra cancer case
will occur for every 105 people taking the medications for about four years
... The maker of the most-used drug in the study ... it had "internal safety
data" contradicting the Lancet study. According to studies run by the
pharmaceutical, there was no link between increased cancer risk and Micardis
... Scientists aren't sure why ARBs might raise the possibility of
developing cancer, though some animal studies suggest the medications help
produce new blood vessels, which would speed tumor growth" - Note:
New blood vessels can be a good thing
like with heart disease

and
PAD and increased
endurance so it may be sacrificing one thing for another.

Would VALUE Cancer Data
Negate Findings of Report? - Medscape, 6/25/10 -
"from a pathophysiological viewpoint, the finding in the meta-analysis
of increased cancer with ARBs in such a short time period--two to four
years--does not make sense: it takes around 10 years to develop lung and
other cancers from smoking, the hypertension doctors argue. Some said
they had discussed the findings with oncologists, who think the concept
is farfetched"

New Review
Reassures on ARB/Cancer Risk, But Questions Linger - Medscape,
11/30/10 - "A new meta-analysis of almost 325
000 individuals from 70 clinical trials has found no excess risk of
cancer or cancer death with any single antihypertensive drug ...
However, a statistically significant increase in cancers among patients
taking an ARB in combination with an ACE inhibitor of roughly 10% means
the authors "cannot rule out" an increased risk of cancer with the
combination of these two medications"

Systematic
review of the effect of telmisartan on insulin sensitivity in hypertensive
patients with insulin resistance or diabetes - J Clin Pharm Ther. 2011 Aug
17 - "Telmisartan is an angiotensin receptor blocker (ARB) originally developed
for the treatment of hypertension. It can also partially activate peroxisome
proliferator-activated receptor (PPAR)-γ, which may improve insulin sensitivity.
This effect may prove useful in hypertensive patients with insulin resistance or
diabetes mellitus. Such activity is more marked than that observed with other
ARBs ... Eight trials involving a total of 763 patients met the inclusion
criteria. Telmisartan was superior to other ARBs in reducing FPG level (mean
difference, -8.63 mg/dL; 95% CI -12.29 mg/dL to -4.98 mg/dL; P < 0.00001) and
increasing adiponectin level (mean difference, 0.93 μg/dL; 95% CI 0.28 μg/dL to
1.59 μg/dL; P = 0.005). At 80 mg dose, telmisartan may reduce FPI level and
HOMA-IR. What is new and Conclusions: The available evidence suggests a
beneficial effect of telmisartan in improving insulin sensitivity in
hypertensive patients with insulin resistance or diabetes as demonstrated by the
decrease in FPG and increase in adiponectin levels. The effect in decreasing FPG
was greater with 80 mg dose than with the 40 mg dose. FPI and insulin resistance
may be improved with 80 mg of telmisartan"

Reduction of
circulating superoxide dismutase activity in type 2 diabetic patients with
microalbuminuria and its modulation by telmisartan therapy - Hypertens Res.
2011 Aug 4 - "Interestingly, the telmisartan treatment not only reduced the
circulating levels of two oxidative stress markers, 8-hydroxy-2'-deoxyguanosine
(8-OHdG) and nitrotyrosine (NT), but also enhanced serum SOD activity. Notably,
a significant correlation was observed between the increase in serum SOD
activity and the reduction in albuminuria. We further compared the
anti-oxidative effect of telmisartan with that of losartan, another member of
the ARB class, by implementing an 8-week interval crossover treatment with these
ARBs in another 12 microalbuminuric type 2 diabetic patients. The patients
showed higher serum SOD activity, and lower circulating levels of 8-OHdG and NT,
during treatment with telmisartan than with losartan. These results suggest that
telmisartan has a more potent antioxidative effect through its ability to
enhance SOD activity in type 2 diabetic patients with microalbuminuria"

Effects of
telmisartan and losartan on cardiovascular protection in Japanese hypertensive
patients - Hypertens Res. 2011 Jul 28 - "A total of 58 patients were
enrolled in the present trial and the follow-up period was 1 year. There were no
significant differences in blood pressure (BP) levels between the telmisartan
group and the losartan group throughout the trial. The percentage of the
patients treated with ARB monotherapy was significantly higher in the
telmisartan group compared with the losartan group. In addition, the progression
of intima-media thickness of common carotid artery was significantly inhibited
in the telmisartan group compared with the losartan group. Neither group
experienced significant changes in cardiac function and LV mass index. There
were no differences between the groups with respect to changes in surrogate
markers such as serum adiponectin, creatinine, homeostasis model assessment
index, plasminogen activator inhibitor-1 and high sensitivity C-reactive
protein. Although BP levels were equal and well controlled in both groups,
telmisartan showed more protective vascular effects than losartan" -

Value of
Angiotensin receptor blocker therapy in diabetes - J Clin Hypertens
(Greenwich). 2011 Apr;13(4):290-5 - "There are more
clinical trials investigating angiotensin receptor blockers (ARBs) in diabetes
than any other drug class, ranging from early "prevention" trials to the
treatment of individuals with advanced organ damage. In its earliest
manifestations, visceral adiposity predisposes to hypertension and hyperglycemia
(metabolic syndrome). In these individuals, ARB therapy delays the progression
to chronic hypertension and may also delay the progression to overt diabetes.
Based on the increased cardiovascular disease risk of the metabolic syndrome,
which is similar to stage 1 hypertension, both lifestyle modification and ARB
therapy are justifiable. ARB therapy has also been found to delay the onset of
microalbuminuria and retinopathy. In established diabetic nephropathy, ARB
therapy is recommended as a standard alternative to angiotensin-converting
enzyme inhibition to reduce macroalbuminuria and delay the progression to
end-stage disease. Finally, large trials in ischemic heart disease, heart
failure, and stroke have demonstrated clear benefits of ARB therapy. Because
ARBs have side effect rates equal to placebo and far lower than any other
antihypertensive drug class, the benefit/risk ratio is highly favorable across
the entire spectrum of diabetic disease. Thus, ARB therapy is a highly
attractive alternative for individuals at any stage of diabetes and with any
pattern of complications"

Angiotensin-Converting Enzyme Inhibitors, Angiotensin II Receptor Blockers and
Diabetes: A Meta-Analysis of Placebo-Controlled Clinical Trials - Am J
Hypertens. 2011 Feb 17 - "new onset diabetes (NOD) ...
Over an average follow-up of 4.0 ± 1.0 years, there were 1,284/15,142 (8.5%)
cases of NOD in active-treated and 1,411/15,130 (9.3%) cases in placebo-treated
patients in the ACE inhibitor trials, and 2,330/18,756 (12.4%) cases in
active-treated and 2,669/18,800 (14.2%) cases in placebo-treated patients in the
ARB trials. Overall, active therapy reduced NOD compared to placebo (odds ratio
(OR) 95%, confidence interval (CI): 0.8 (0.8-0.9); P < 0.01). Both ACE
inhibitors (OR 95%, CI: 0.8 (0.7-1.0); P = 0.07) and ARBs (OR 95%, CI: 0.8
(0.8-0.9); P < 0.01) reduced NOD as compared to placebo. Active treatment
reduced CV mortality (OR 95%, CI: 0.9 (0.8-1.0); P < 0.01) and had a favorable
impact on non-CV mortality (OR 95%, CI: 0.7 (0.9-1.0); P = 0.2) as compared to
placebo.ConclusionsOur findings demonstrated that ACE inhibitors or ARBs should
be preferred in patients with clinical conditions that may increase risk of NOD,
since these drugs reduced NOD incidence. In addition, these drugs have favorable
effects on CV and non-CV mortality in high CV risk patients"

Inhibition
of intestinal cholesterol absorption might explain cholesterol-lowering effect
of telmisartan - J Clin Pharm Ther. 2011 Feb;36(1):103-10 -
"Recently, it
has been demonstrated that telmisartan also lowers the levels of total
cholesterol and low-density lipoprotein (LDL) cholesterol levels ... Our results
suggest that the cholesterol-lowering effect of telmisartan might be caused by
inhibition of cholesterol absorption, whereas that of statins is by inhibition
of cholesterol synthesis. If confirmed, co-treatment with the two agents may be
useful for synergistically lowering cholesterol in hypertensive patients"

Telmisartan Provides Better Renal Protection Than Valsartan in a Rat Model
of Metabolic Syndrome - Am J Hypertens. 2011 Mar 17 -
"spontaneously hypertensive rats (SHR) ... SHR were
fed either normal (SHR-NF, 7% fat) or high fat (SHR-HF, 36% fat) diet and
treated with an ARB for 10 weeks.ResultsBlood pressure was similar between
SHR-NF (190 ± 3 mm Hg) and SHR-HF (192 ± 4 mm Hg) at the end of the 10 week
period. Telmisartan and valsartan decreased blood pressure to similar
extents in SHR-NF and SHR-HF groups. Body weight was significantly higher in
SHR-HF (368 ± 5 g) compared to SHR-NF (328 ± 7 g). Telmisartan but not
valsartan significantly reduced the body weight gain in SHR-HF. Telmisartan
was also more effective than valsartan in improving glycemic and lipid
status in SHR-HF. Monocyte chemoattractant protein-1 (MCP-1), an
inflammatory marker, was higher in SHR-HF (24 ± 2 ng/d) compared to SHR-NF
(14 ± 5 ng/d). Telmisartan reduced MCP-1 excretion in both SHR-HF and SHR-NF
to a greater extent than valsartan. An indicator of renal injury, urinary
albumin excretion increased to 85 ± 8 mg/d in SHR-HF compared to 54 ± 9 mg/d
in SHR-NF. Telmisartan (23 ± 5 mg/d) was more effective than valsartan (45 ±
3 mg/d) in lowering urinary albumin excretion in SHR-HF. Moreover,
telmisartan reduced glomerular damage to a greater extent than valsartan in
the SHR-HF.ConclusionsCollectively, our data demonstrate that telmisartan
was more effective than valsartan in reducing body weight gain, renal
inflammation, and renal injury in a rat model of cardiometabolic syndrome"

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 oxidative stress"
- Note: There are several PARR receptor activators such as the blood
pressure drug telmisartan and the diabetes medication
Actos (some doctors have
criticized me for years for taking it for anti-aging). I've started a
webpage on PPARs. When I get a chance
I'll search my site and put the articles on it.

Telmisartan:
a Different Angiotensin II Receptor Blocker Protecting a Different Population?
- J Int Med Res. 2009;37(6):1662-1679 - "Telmisartan has a unique profile among
ARBs, with a high affinity for the angiotensin II type 1 receptor, a long
duration of receptor binding, a high lipophilicity and a long plasma half life.
This leads to sustained and powerful blood pressure lowering when compared with
the first marketed ARBs, such as losartan and valsartan. Some pharmacological
properties of telmisartan clearly distinguish it from other members of the ARB
class and may contribute to the clinical effects seen with telmisartan. A class
effect for ARBs cannot be assumed. To date, telmisartan is the only ARB that has
been shown to reduce cardiovascular risk in at-risk cardiovascular patients"

Antihypertensive efficacy of telmisartan vs ramipril over the 24-h dosing period, including the critical early morning hours: a pooled analysis of the PRISMA I and II randomized trials - J Hum Hypertens. 2009 Feb 19 -
"The adjusted mean treatment differences in the last 6-h mean ambulatory SBP/DBP were -5.8/-4.2 mm Hg after 8 weeks and -4.1/-3.0 mm Hg after 14 weeks, in favour of telmisartan (P<0.0001 for all four comparisons). Secondary end point results, including the mean 24-h ambulatory BP monitoring, day- and night-time BP and 24-h BP load, also significantly favoured telmisartan (P<0.0001). Both treatments were well tolerated; adverse events, including cough, were less common with telmisartan. These findings suggest that telmisartan is more effective than ramipril throughout the 24-h period and during the EMBPS; this may be attributable to telmisartan's long duration of effect, which is sustained throughout the 24-h dosing period"

Telmisartan improves insulin resistance in high renin nonmodulating
salt-sensitive hypertensives - J Hypertens. 2008 Dec;26(12):2393-8 -
"Nonmodulating (NMHT) is a high-renin subtype of
salt sensitive hypertension, which additionally develops insulin resistance
and oxidative stress. Conversely, modulating hypertensives (MHT) normally
regulates renal hemodynamics after high sodium intake without metabolic
impairment ... In NMHT, telmisartan, after 3 months treatment, significantly
reduced fasting and 120 min insulinemia (fasting: 8.4 +/- 2, 120 min: 25 +/-
10 muU%; P < 0.01) compared either to basal values or ramipril treatment.
Similarly, only in NMHT, compared with basal values and ramipril treatment,
telmisartan improved the HOMA-IR index in both MHT (2.76 +/- 0.16 to 2.24
+/- 0.18, P < 0.05) and NMHT (from: 4.4 +/- 1 to 2.3 +/- 0.7) and
triglyceride plasma levels (MHT: from 139 +/- 1.85 to 122 +/- 2.4 mg%, P <
0.05; NMHT: from: 223 +/- 12 to 146 +/- 10 mg%, P < 0.01). Finally, highly
sensitive C-protein-reactive protein values were higher in NMHT (0.33 +/-
0.07 mg.dl) than in MHT (0.14 +/- 0.06 mg.dl; P < 0.01). Both treatments
reduced highly sensitive C-protein-reactive protein in NMHT. (ramipril from
0.32 +/- 0.05 mg.dl to 0.26 +/- 0.06 m.dl (P < 0.05) and telmisartan from
0.34 +/- 0.05+/- to 0.20 +/- 0.05 mg.dl (P < 0.01). CONCLUSION: Our data
suggest that the improvement of the insulin sensitivity by telmisartan,
instead of a similar effect on blood pressure shown by both drugs, could be
ascribed to the PPAR agonistic action of telmisartan. This opens an
interesting therapeutic approach for patients with hypertension and altered
glycemic metabolism"

which has less PPAR-gamma agonistic effect, also inhibited Abeta-injection-induced
cognitive decline; however the effect was smaller than that of telmisartan
and was not affected by GW9662. Immunohistochemical staining for Abeta
showed the reduced Abeta deposition in telmisartan-treated mice. However,
this reduction was not observed in mice co-administered GW9662. These
findings suggest that ARB has a preventive effect on cognitive impairment in
Alzheimer disease, and telmisartan, with PPAR-gamma activation, could exert
a stronger effect"

Microalbuminuria Reduction with Telmisartan in Normotensive and Hypertensive
Japanese Patients with Type 2 Diabetes: A Post-Hoc Analysis of the Incipient
to Overt: Angiotensin II Blocker, Telmisartan, Investigation on Type 2
Diabetic Nephropathy (INNOVATION) Study - Hypertens Res. 2008
Apr;31(4):657-64 - "The patients treated with either
dose of telmisartan showed lower transition rates from microalbuminuria to
overt nephropathy compared to the placebo group. In addition, more patients
on telmisartan reverted to normoalbuminuria (UACR<30 mg/g creatinine): 15.5%
of the 40 mg group, 19.6% of the 80 mg group, and 1.9% of the placebo group
... Side effects did not differ among the groups. The present study
demonstrates that telmisartan prevents the progression of microalbuminuria
(in some cases induces remission of albuminuria) in normotensive Japanese
patients with type 2 diabetes. Telmisartan is shown to be safe and well
tolerated in these patients"

advantages of ARBs that make them a possible therapeutic option for treating
NASH and MS: their specific antihypertensive effect, and their impact on liver
fibrosis. In light of this, and based on the current evidence (including
existent human studies), we can speculate that some ARBs like telmisartan,
candesartan, and losartan can be beneficial in treating NASH/NAFLD and its
consequences, and further larger controlled clinical trials will bring
consistent data into this field"

Effect of irbesartan on erectile function in patients with hypertension and
metabolic syndrome - Int J Impot Res. 2008 Jul 3 -
"Erectile function increased significantly
(P<0.0001) after 6 months of treatment with irbesartan, irrespective of
dosage and independent of additional treatment with hydrochlorothiazide.
Prevalence of ED declined to 63.7% from 78.5% at baseline, along with a
significant increase in orgasmic function (P<0.001) and intercourse
satisfaction (P<0.001). Treatment with irbesartan alone, as well as in
combination with hydrochlorothiazide is associated with an improvement of
sexual desire, frequency of sexual contacts and erectile function in
hypertensive patients with the metabolic syndrome. These results suggest a
beneficial role of angiotensin receptor antagonists in the treatment of
metabolic syndrome, and ED" - Note: I've been suggesting
telmisartan (an ARB) for some time as the first line treatment for

Effect
of Telmisartan on Nitric Oxide-Asymmetrical Dimethylarginine System. Role of
Angiotensin II Type 1 Receptor and Peroxisome Proliferator Activated
Receptor {gamma} Signaling During Endothelial Aging - Hypertension. 2008
Feb 4 - "Telmisartan, in addition to blocking
angiotensin (Ang) II type 1 receptor (AT1R), activates peroxisome
proliferator activated receptor gamma (PPARgamma) signaling that interferes
with nitric oxide (NO) system. Because aging of endothelial cells (ECs) is
hallmarked by a reduction in NO synthesis, we hypothesized that telmisartan
increases NO formation by regulated asymmetrical dimethylarginine (ADMA)-dimethylarginine
dimethylaminohydrolase (DDAH)-system through blocking AT1R and activating
PPARgamma signaling ... During the process of aging, PPARgamma protein
expression decreased significantly, whereas the expression of AT1R
increased. Telmisartan reversed these effects and dose-dependently decreased
reactive oxygen species and 8-iso-prostaglandin (PG) F2alpha formation ...
telmisartan mainly by activating PPARgamma signaling can alter the
catabolism and release of ADMA as an important cardiovascular risk factor.
We therefore propose that telmisartan translationally and
posttranslationally upregulated DDAH expression via activation of PPARgamma
signaling, causing ADMA to diminish and increase NO synthesis sufficient to
delay senescence"

Evidence-Based
Treatment of Hypertension: What's the Role of Angiotensin II Receptor
Blockers? - Medscape, 4/8/05 - "The ARBs are highly effective in lowering blood pressure and reducing
cardiovascular mortality. They also appear to provide additional renal
protection in patients with diabetes, and this effect is independent of
their effect on blood pressure. Combinations of ARBs with drugs from other
classes such as ACE inhibitors have been found to be highly effective; they
may permit lower doses of ACE inhibitors to be used than in monotherapy,
which may lower the incidence of dose-related adverse effects. The ARBs
themselves are very well tolerated and are not associated with the
side-effects known to cause compliance problems with beta blockers, ACE
inhibitors and calcium channel blockers such as impotence, dry cough and

Telmisartan, ramipril and their combination improve endothelial function in
different tissues in a murine model of cholesterol-induced atherosclerosis
- Br J Pharmacol. 2011 Feb 16 - "Erectile
dysfunction correlates with cardiovascular disease and its common risk
factors due to the development of endothelial dysfunction. Positive effects
on endothelial and erectile function have been described for substances
inhibiting the renin-angiotensin-system ... Wildtype (WT, C57/B6) and ApoE(-/-)
mice were treated with a cholesterol-rich diet for 8 weeks. ApoE(-/-) mice
were supplemented with either telmisartan (20mg/kg/day), ramipril
(2.5mg/kg/day) or the combination thereof. Key results: Systolic blood
pressure significantly decreased in treatment groups (p < 0.001), with
significantly smaller reduction under ramipril monotherapy (p < 0.05).
Endothelial function (assessed by pharmacological stimulation of aortic
rings and CC in organ bath chambers) was impaired in ApoE(-/-) mice compared
to WT animals, which was improved by all three treatments to a comparable
extent (p < 0.05). Atherosclerotic lesion size in the ascending aorta and
aortic sinus (p < 0.001), the amount of lipid peroxides in cavernosal and
aortic tissue (p < 0.05) and free radical load (DHE-stain) (p < 0.05) were
enhanced in untreated ApoE(-/-) mice in comparison to WT animals and were
significantly reduced by either treatment. In penile tissue, expression of
eNOS could be restored by RAAS-blockade. Conclusions and implications:
Telmisartan and ramipril significantly improved endothelial function of
aortic and cavernosal tissues in ApoE(-/-) via reduction of oxidative
stress. Combination of both agents does not enhance beneficial effects
significantly"

Function - Hypertens Res. 2008 Aug;31(8):1603-10 -
"these results suggest that the angiotensin
I-converting enzyme inhibitor perindopril is superior to the calcium channel
blocker amlodipine for reducing vascular endothelial dysfunction when
co-administered with angiotensin receptor blockers in patients with
essential hypertension"

Hypertens Res. 2008 Mar;31(3):575-84 - "1) vehicle
(control), 2) the ACEI enalapril (E: 3 mg/kg/day), 3) the ARB losartan (L:
30 mg/kg/day) and 4) enalapril (1.5 mg/kg/day) + losartan (15 mg/kg/day)
(E+L). Intra-aortic infusion of ACh produced an increase in plasma NO
concentration, which was significantly greater with all the drug treatments
than with the control. E increased ACh-induced NO significantly more than L
(by 6.9 nmol/L, and 4.7 nmol/L, respectively). E+L increased ACh-induced NO
by 9.5 nmol/L, significantly more than either E or L ... the combined
treatment with an ACEI and an ARB may have additive protective effects on
endothelial function as well as atherosclerotic change"

Angiotensin-Converting Enzyme Inhibitors, Angiotensin Receptor Blockers, or
Both for Patients With Proteinuria? A Best Evidence Review - Medscape,
5/20/08 - "Most significantly, the addition of ACEIs
to ARBs reduced proteinuria to a greater degree than ARBs alone (ratio of
means 0.76 at 1 to 4 months and 0.75 at 5 to 12 months). Combination therapy
was also superior to treatment with ACEIs alone ... The 2 important
conclusions that can be drawn from this meta-analysis are that ARBs are not
superior to ACEIs in improving proteinuria, and that the combination of
these 2 treatments appears superior in this outcome compared with either
treatment alone ... Two of the biggest safety concerns regarding the
combination therapy include the risks for hyperkalemia and acute worsening
of renal function. A review of the literature, however, suggests that these
risks may not be significantly worse with combination treatment vs
monotherapy"

ACE Inhibitors Plus ARBs Reduce Proteinuria But Increase Kidney Damage -
Doctor's Guide, 8/15/08 - "in people at high
vascular risk, telmisartan's effects on major renal outcomes are similar to
[those of] ramipril. Although combination therapy reduces proteinuria to a
greater extent than monotherapy, overall it worsens major renal outcomes"

Telmisartan, Ramipril, or Both in Patients at High Risk for Vascular Events
- N Engl J Med. 2008 Mar 31 - "Telmisartan was
equivalent to ramipril in patients with vascular disease or high-risk
diabetes and was associated with less angioedema. The combination of the two
drugs was associated with more adverse events without an increase in
benefit" - Yeah but if you have to go with two drugs it sure seems
like it's the least of all the evils regarding side effects.

ACE
Inhibitors May Protect Diabetics From Cancer, Peptic Ulcer - Medscape,
12/19/08 - "There was a significant association
between ACE inhibitor use and the risk for cancer, with an adjusted odds
ratio of 0.59 ... The rate of cancer among users of ACE inhibitors was 10%
vs 15% for nonusers ... There was also a significant association between ACE
inhibitor use and peptic ulcer disease, with an odds ratio of 0.68 ... The
rate of peptic ulcer disease among ACE inhibitor users was 12% vs 16% among
nonusers"

Establishing A New Option for Target-organ Protection: Rationale for ARB
Plus ACE Inhibitor Combination Therapy - Am J Hypertens. 2008 Jan 24 -
"Combination therapy targeting RAS activation may
reduce target-organ damage and provide superior blood pressure (BP) control;
combining angiotensin-converting enzyme (ACE) inhibitors and angiotensin II
receptor blockers (ARBs) represents one possible approach"

Rationale for double renin-angiotensin-aldosterone system blockade - Am
J Cardiol. 2007 Aug 6;100(3A):25J-31J - "The
clinical benefits of both angiotensin-converting enzyme (ACE) inhibitors and
angiotensin receptor blockers (ARBs) extend beyond blood pressure reduction
to encompass tissue-protective effects in target organs, such as the heart,
vasculature, and kidneys, that underlie the reductions in cardiovascular
mortality and morbidity seen in large outcome trials. However, these effects
are achieved by different mechanisms. ACE inhibitors reduce circulating and
tissue angiotensin II levels and potentiate the beneficial effects of
bradykinin, including generation of nitric oxide (NO). By contrast, the
protective effects of ARBs are owing to the blockade of the angiotensin II
type 1 (AT(1)) receptors and possibly also to the stimulation of angiotensin
II type 2 (AT(2)) receptors, again resulting in NO release. In addition,
some ARBs, such as telmisartan, are selective activators of peroxisome
proliferator-activated receptor-gamma (PPAR-gamma), thereby increasing
insulin sensitivity. In contrast to other PPAR-gamma ligands, such as the
thiazolidinediones, activation of this receptor by telmisartan does not
result in weight gain. The complementary mechanisms of action of ACE
inhibitors and ARBs create a rationale for combination therapy in high-risk
patients"

New opportunities in cardiovascular patient management: a survey of clinical
data on the combination of angiotensin-converting enzyme inhibitors and
angiotensin receptor blockers - Am J Cardiol. 2007 Aug 6;100(3A):45J-52J
- "Angiotensin-converting enzyme (ACE) inhibitors
and angiotensin receptor blockers (ARBs) differ in their actions on the
renin-angiotensin-aldosterone system (RAAS). ACE inhibitors prevent the
formation of angiotensin II, although angiotensin II may still be generated
by alternative pathways. However, ACE inhibitors interrupt bradykinin
breakdown, which in turn potentially enhances nitric oxide and prostacyclin
mechanisms. In contrast, ARBs selectively prevent the binding of angiotensin
II to the angiotensin type 1 (AT(1)) receptor while leaving the potentially
beneficial effects of the AT(2) receptor unaffected. The supposition is that
dual blockade of the RAAS effectively overcomes the harmful effects of
angiotensin II mediated by the AT(1) receptor while offering the additional
effects of the ACE inhibitor"

considerations - J Clin Hypertens (Greenwich). 2007 Jan;9(1):78-86. -
"The individual gains seen with each
of these drug classes have led to speculation that their combination might
offer additive if not synergistic outcome benefits. The foundation of this
hypothesis, although biologically possible, has thus far not been
sufficiently well proven to support the everyday use of these 2 drug classes
in combination. Additional outcomes trials, which are currently proceeding
to their conclusion, may provide the necessary proof to support an expanded
use of these 2 drug classes in combination"

Do ACE
inhibitors and ARBs mix well? Analysis urges caution - theheart.org,
10/10/07 - "patients receiving both an ACE inhibitor
and an ARB were more likely not to comply with therapy due to side effects,
which included hypotension, cough, angioedema, worsening renal function as
defined by a change in serum creatinine >0.5 mg/dL, hyperkalemia as defined
by serum potassium level changes >5.5 mEq/L, and symptomatic hypotension"
