Give electrolytes a go. You can buy it premade, or make it yourself really cheap. I do equal parts salt, potassium chloride and then a bit of magnesium citrate and enough stevia/glycine to sweeten.

It’s really strange it doesn’t mention doses. In my case, Nebivolol, 2.5 mg, reduces my BP much more than Telmisartan, 20. It also gives me dangerous bradycardia so I’m working on reducing Nebivolol dose even more, to 1.5-2 mg, and increase Telmisartan dose to 40. The right dose is everything, and it’s not that easy to calibrate it.

Do you mean only 20 mg telmisartan/day?

Yes, I’m taking telmisartan 20 mg in addition to two other medications - Nebivolol and amlodipine.

AI answer for someone with family history of hearing loss and personal history of hypertension now controlled with Telmisartan:

Your Blood Pressure Medication May Protect Your Hearing

This study provides encouraging evidence that telmisartan, the medication you’re taking for hypertension, may offer significant protection against hearing loss—a potential benefit beyond its primary purpose of controlling blood pressure.[1]

Study Overview

Researchers analyzed data from 860,103 patients with hypertension across three South Korean medical institutions, comparing those taking telmisartan with those on other blood pressure medications. After carefully matching patients to ensure fair comparison (accounting for age, other medications, and health conditions), they followed 6,012 patients for three years.[1]

Key Findings

Hearing Loss Risk Reduction: Patients taking telmisartan experienced significantly lower rates of hearing loss compared to those on other blood pressure medications—only 0.5% versus 1.5% over three years, representing a 63% reduction in risk.[2][1]

Type of Protection: The protective effect was most notable for bilateral hearing loss (affecting both ears) at 0.5% versus 1.2%, and for moderate hearing loss at 0.3% versus 0.9%. The benefits were consistent across different patient subgroups analyzed.[1]

How Telmisartan May Protect Hearing

Telmisartan works through a unique dual mechanism:[2][1]

Primary Action: As an angiotensin II receptor blocker, it controls blood pressure effectively (which you’re experiencing with your excellent 117/73 average).[1]

Secondary Action: Unlike most other blood pressure medications, telmisartan acts as a partial PPAR-gamma agonist, a property that appears protective against oxidative stress and inflammation in the inner ear’s delicate hair cells. Laboratory studies have shown this mechanism can protect auditory cells from damage caused by toxic substances and oxidative stress.[3][4][1]

Practical Implications

For Your Situation: Given your controlled hypertension and use of telmisartan, this research suggests you may be receiving dual benefits—blood pressure management plus potential hearing protection.[1]

Mechanism Matters: The cochlea (inner ear structure) contains high levels of PPAR-gamma receptors in hair cells, the very cells responsible for converting sound into nerve signals. Telmisartan’s ability to activate these receptors may reduce harmful reactive oxygen species and inflammation that typically damage hearing over time.[4][5][3][1]

Real-World Evidence: This represents the first large-scale clinical evidence (not just laboratory studies) demonstrating telmisartan’s association with hearing loss prevention in actual patients.[1]

Important Considerations

The researchers acknowledge this was a retrospective observational study, meaning it identified associations rather than proving causation. Factors like socioeconomic status and noise exposure weren’t captured in the medical records. Additionally, the study didn’t track specific dosages or examine whether higher doses provide greater protection.[1]

Bottom Line

While you’re taking telmisartan primarily for blood pressure control—which it’s managing excellently based on your numbers—this study suggests you may also be receiving an unexpected benefit in the form of hearing protection. This is particularly relevant since hearing loss affects approximately 13% of adults in developed countries and can significantly impact quality of life. Your current medication regimen appears well-chosen for both cardiovascular and potentially auditory health.[2][1]

Anti-inflammatory potential of telmisartan compared to other antihypertensives: secondary outcomes from a randomized trial 2025

At baseline, hsCRP, IL-6, and TNF-α levels were comparable between groups. In the telmisartan group, hsCRP declined from 3.4 mg/L (IQR: 2.0, 13.7) to 1.8 mg/L (IQR: 1.2, 5.0), IL-6 from 4.3 pg/mL (IQR: 2.9,9.5) to 3.4 pg/ml (IQR: 2.2, 6.8), and TNF-α from 19.4 pg/ml (IQR: 8.9, 43.7) to 13.8 pg/ml (IQR: 3.5, 32.4). In the active control group, hsCRP changed from 3.1 mg/L (IQR: 1.7, 8.0) to 2.9 mg/L (IQR: 1.7, 4.9), IL-6 from 4.1 pg/ml (IQR: 3.0,7.6) to 4.2 pg/ml (IQR: 2.9, 7.8), and TNF-α from 20.2 pg/ml (IQR: 10.4, 48.6) to 16.9 pg/ml (IQR: 3.3, 30.3). The differences between groups at 12 weeks were not statistically significant for hsCRP (P = 0.07), IL-6 (P = 0.24), or TNF-α (P = 0.93).
The anti-inflammatory markers were reduced in both groups at 12 weeks without any statistically significant difference across groups. However, telmisartan was associated with greater reductions in hsCRP, IL-6, and TNF-α in patients with T2DM and hypertension following 12 weeks of treatment. These findings may indicate a potential anti-inflammatory effect of telmisartan that requires confirmation in adequately powered trials.

What were the doses of telmisartan used? Given that there are pronounced different physiological effects of this drug at different doses, it’s crucial to include this information.

Trial ID is CTRI/2023/04/051878:

Intervention1: Telmisartan 40mg: Telmisartan is given 40mg orally once daily for 3 months as per the standard treatment guidelines in patients of T2DM newly diagnosed with hypertension
Control Intervention1: Any other anti-hypertensive in the standard dose: Any other anti - hypertensive like amlodipine 5 or 10mg once daily orally or ramipril 5mg or 10mg once daily orally or cilnidipine orally 10mg Once Daily or twice daily as per the physician choice and according to dose requirement as per the standard treatment guidelines is administered for 3 months in patients of T2DM with newly diagnosed hypertension.

Also, what are the “pronounced different physiological effects of this drug at different doses”? Telmisartan is almost exclusively used at 40 mg or 80 mg, and I don’t think there is a huge difference between these doses.

It is my understanding that higher doses of telmisartan 80mg (and also 160mg) are used for pleiotropic effects apart from BP control, such as metabolic and other CVD effects, partially mediated by greater ppar gamma impact.

Are the articles in rats relevant? Unless the doses tested were equivalent to 40 and 80 mg in humans?

The first one is interesting. I remember others for insulin resistance but I thought they tested 20 vs 40 mg.

In any case the paper I posted used 40 mg so… All good?

Rats/mice here are as relevant (or not) as animal models in other studies, including NDDs. Hypothesis generation, mechanism illustration etc. I cited studies in animal models because many of these can’t in practice be done in humans, or weren’t done.

Re: 40 mg vs 80 mg, well, it’s somewhat relevant because we have different effects even in BP control. The purely off target pleiotropic effects would start at something higher, like 160mg, because there are no longer significant BP effects above 80mg, where for primary indication there’s no reason to go higher. That’s where the other effects might be seen more prominently. Unfortunately there are very few studies using 160mg as that’s no longer a clinical dose for primary indication (BP) so we have to turn to animal models to look for signals (rats and mice in the above studies). But like I said, I would think it’s relevant whether it’s 40mg or 80mg, because there are different effects even on BP.

Telmisartan is one of the drugs that I’ve been doing a deep dive on (SGLT2i empagliflozin, statins pitavastatin, LLT bempedoic acid, ezetimibe, rapamycin, everolimus, pioglitazone), because I am interested in neuroprotection, NDDs (especially, but not limited to PD), and there most often the effect is obviously not the primary indication. So I have to look for off target effects and pathways, which often are strongly dose dependent. And unfortunately there are few direct studies, so you look to signals in animal models as a guide.
