I’ve just checked nebivolol briefly. It’s interesting as it might have fewer side effects than other beta-blockers, but I don’t think it’s good enough to replace other antihypertensive drugs.
Apparently (Wikipedia, I didn’t double-check the sources), it is only highly cardioselective for β1 at low doses (5 mg), then loses its cardioselectivity and “nebivolol is also not cardioselective when taken by patients with a genetic makeup that makes them “poor metabolizers” of nebivolol (and other drugs) or with CYP2D6 inhibitors” (how can we check that?)
According to the 2023 ESH Guidelines for the management of arterial hypertension The Task Force for the management of arterial hypertension of the European Society of Hypertension: “However, there are no outcome trials with vasodilating BBs in hypertensive patients, and the same applies to bisoprolol. There are also some recent large real-world studies with vasodilator BBs conducted in the USA, with inconsistent results. In one study, there was no statistically significant difference in CV outcomes between 118 133 patients receiving either nebivolol or carvedilol and 267 891 patients receiving atenolol [588]. In other studies, use of nebivolol led to greater CV protection compared with use of atenolol or metoprolol [589,590].”
Also, in the recent EPITERNA paper, nebivolol was not associated with life extension, although not statistically significant, it was more on the side of “lifespan reduction”. In “Association of cardiovascular disease management drugs with Lewy body dementia: a case–control study”, nebivolol didn’t perform better than other antihypertensive (and especially not better than the best in class like sartans and their combinations with CCBs or thiazide).
There’s one ongoing trial comparing nebivolol to telmisartan, with results expected in 2026. Other than that, I couldn’t find interesting trials of nebivolol so I assume that it doesn’t interest researchers that much.
Nebivolol might be interesting in quadruple low‐dose treatment. For instance, the QUARTET USA trial tried candesartan, 2 mg, amlodipine, 1.25 mg, indapamide, 0.625 mg, and bisoprolol, 2.5 mg, once daily. While QUARTET Australia tested irbesartan at 37.5 mg, amlodipine at 1.25 mg, indapamide at 0.625 mg, and bisoprolol at 2.5 mg.
We’ll get the ITP results for nebivolol next year. I understand that when a compound works, the ITP team notices it early on and mentions it informally (on social networks or in podcasts) and/or starts scheduling a second round trial. For instance, Sodium Thiosulfate (STS) is part of the same batch as nebivolol, and as it seems promising, it was selected again last year to be re-tested at a different dose and confirms the findings. Does it mean nebivolol failed?
Beta-blockers are also associated with increased risk of Parkinson’s disease. (see “Our comprehensive study indicated that regular NBB use is associated with an increased risk of PD. In light of the detrimental effects of NBBs on PD, some people should choose alternative antihypertensive treatments.” in Nonselective beta-adrenoceptor blocker use and risk of Parkinson’s disease: from multiple real-world evidence 2023). There might be reverse causation as propranolol is used for mild essential tremors that can be early Parkinson’s symptoms. Still, unless I can find evidence that nebivolol is associated with a significantly lower risk of Parkinson’s and Alzheimer’s and other dementia and NDDs vs telmisartan, amlodipine and indapamide, I see no reason to use it.
