So, the 2002 study was a good study and is likely to be as valid as the newer study. Newer does not necessarily mean better.
Also from the study you cite: “Across secondary and safety outcomes, patients on ARBs had significantly lower risk of angioedema, cough, pancreatitis, and GI bleeding.”
From the study I cite:
“The relative risk of any stroke was reduced by 32% (156 v 226) in the ramipril group compared with the placebo group, and the relative risk of fatal stroke was reduced by 61% (17 v 44”)
You are in denial about this?

The 2002 study was good. The more recent ones I mentioned are better. (And not funded by the drug manufacturer… But I’ll put this aside.)
The more recent studies I shared showed that ramipril (resp. other ACEIs) was not superior (and even potentially a bit inferior) to telmisartan (resp. other ARBs) in terms of stroke (and other end points) in hypertensive people. That’s it. There’s 0 studies or papers suggesting otherwise. If you find a paper comparing telmisartan to ramipril and finding a higher rate of stroke in telmisartan, let me know!
(also in the 2002 study, “Participants were aged 55 or over and were at high risk of cardiovascular events because of previous coronary artery disease, cerebrovascular disease, or peripheral arterial disease or diabetes plus one additional risk factor.” I don’t know if these are the traditional inclusion criteria for antihypertensive drug trials as I cannot find in the paper the list of these “additional risk factors”.)
Yes, that’s why telmisartan is better than ramipril. (do you know that telmisartan is an ARB?!)
Yes, it’s amazing. And the ONTARGET trial comparing telmisartan to ramipril found that telmisartan was doing as good if not better.

Okay, okay! I won’t switch from telmisartan.

Haha it’s okay. I just didn’t want people reading us to believe that ACEI/ramipril was significantly better than ARB/telmisartan for stroke prevention as current evidence doesn’t show this. Of course, future studies might change the conclusion. But as of today, the best first line anti hypertensive seems to be a combination [telmisartan + (amlodipine and/or indapamide)].

Just to be clear, is there an intrinsic reason why telmisartan + amlodipine and/or indapamide are superior to higher-dose telmisartan, or is it simply the aversion of possible side effects that come from higher-dose telmisartan? In other words, if a patient is effectively controlling hypertension with 80 mg telmisartan without side effects, is it nonetheless beneficial to switch to lower-dose telmisartan + amlodipine and/or indapamide?

I mentioned the two-drug combination for therapy initiation only. Here’s the rationale: Optimal Blood Pressure we Should Target? Systolic Under 110 or 100? - #244 by adssx

Preprint but great team: Association between Class of Antihypertensive Drugs and Risk of Incident Dementia: A Multinational Population-Based Cohort Study 2024
1,982,839 individuals followed over more than 6 years in 4 countries (UK, HK, Sweden, and Australia):
Our study supports the use of ARBs compared to ACEI when considering the risk of cognitive decline and dementia, based on a multi-ethnic cohort with a long median follow-up time.
Unfortunately, they didn’t do the job properly and didn’t distinguish DHP CCBs (e.g., amlodipine, associated in many studies with lower rate of dementia) from non-DHP CCBs and thiazide/thiazide-like diuretics (e.g., indapamide) from other diuretics (e.g., loop diuretics).

What is the lowest effective dose of Telmisartan? I saw you guys mentioned 20 mg, but my pharmacy only gives 40 mg. Is 20 mg still highly effective? @adssx @desertshores
I broke 40 milligrams of telmisartan into two parts, so half a tablet is 20 milligrams per day

Thank you. I just did a search and it confirms you can split it in half with no lose of efficacy

You can split pills, but off-target benefits of telmisartan seem to appear above 40 mg per day (for insulin resistance) and 80 mg per day (for PPAR-alpha inhibition).

@DrFraser
Thanks for the post. In another post, you mention you like to increase telmisartan up to 80 mg for its effects on ppar. Can you elaborate on your decision tree whether to go to 40 vs 80 mg in any given individual? Thx.

In general, so long as there is no contraindication (e.g. they are having some renal dysfunction, hyperkalemia, hypotension) with lower dose telmisartan, I’m pushing to 80 mg on this, as most individuals are interested in neuroprotection. There is some literature stating the effect probably is still not that potent at 80 mg, and potentially going to 160 mg. I’ve not done that yet.
It really is an issue of tolerability and lack of contraindication - and if those conditions are met, 80 mg is my approach before adding a second agent for hypertension.
There are lots of factors that might push me in individual cases to choose something different first, if they had a specific other condition favoring another compound, but patients with normal labs, and enough BP to tolerate this medication, will usually have it recommended by me, for neuroprotection and hypertension (as defined by SBP>120 not SBP>130-140 mmHg).
Hopefully that answers the question?

Yes, thank you. Very helpful.

Would we have to worry about any nutrient deficiencies from going with an 80mg or higher dose of Telmisartan?
At the 80 mg dose, I don’t think it is potent enough to have me head down that rabbit hole. It would be unclear to me with stronger PPAR effects as to whether any situation beyond a diverse diet, mostly plants, appropriate fiber would have any evidence.
I was looking through this recently - and as much as it modulates a lot of things, I don’t really see anything I’d recommend on diet beyond my usual advice.
I’d love if you or someone else had some evidence on this or concerns as it is a good question, and one I’ve not worried about at the 80 mg - but perhaps at 160 mg, it might be an issue to contemplate at least.

Non-HLA angiotensin-type-1 receptor autoantibodies mediate the long-term loss of grafted neurons in Parkinson’s disease models 2024
The results suggest the use of ARBs such as candesartan in PD patients, particularly before and after dopaminergic grafts, and the need to monitor AT1-AA levels in PD patients, particularly in those candidates for dopaminergic grafting.

I’m tolerating the 80mg dose of telmisartan well, with the only side effect being a mild headache at night, but not enough to significantly interfere w/sleep.
The hard part has been trying to get off my beta-blocker (nebivolol). Everything is good while at 5mg (a pretty low dose), but even slowly weaning down to 2.5mg for a week and then stopping after another week caused significant tachycardia, albeit normal blood pressure. Back to 5mg now, and everything is great. It would be great to completely come off, but it might require an even slower taper.

Why do you want to come off nebivolol? If you have tachycardia, it’s a great treatment, isn’t it? Alternatively, you could use carvedilol?

I only got tachycardia as a result of coming off the beta-blocker, since the medication lowers heart rate and my heart has become accustomed to being on nebivolol for so many years. It’s likely just going to require a significantly longer time to taper off.
