MONDAY, Feb. 8, 2021 (HealthDay News) — While scientists nonetheless do not know what causes Parkinson’s disease, new analysis exhibits an affiliation between a drug that some males take for an enlarged prostate situation and a diminished threat of growing the sickness.

A workforce led by scientists on the University of Iowa, working in collaboration with researchers in Denmark and China, discovered that the drug terazosin and related drugs might have the potential to forestall or delay this debilitating neurodegenerative situation.

The researchers discovered that males taking terazosin had been between 12% and 37% much less more likely to develop Parkinson’s illness in the course of the follow-up interval than males taking one other drug for an enlarged prostate known as tamsulosin.

“We don’t really have anything that can slow down the progression of the disease or stop the disease from progressing,” mentioned research creator Jacob Simmering, an assistant professor within the College of Medicine on the University of Iowa, in Iowa City.

“We don’t have any neuroprotective treatments and we’ve tried things and nothing’s really panned out in human trials so far. There’s really a critical need to have something to try to slow this down, not just to alleviate some of the symptoms, but actually make people’s lives better,” Simmering mentioned.


The research used databases from the United States and Denmark to analysis the problem. The knowledge included practically 150,000 males who had simply began on terazosin and matched them with about 150,000 males who had began taking tamsulosin.

Using knowledge from the 2 totally different nations supplied a extra full image, Simmering mentioned. The knowledge are from 1996 to 2017 in Denmark and 2001 to 2017 within the United States.

“It was nice that we have two different databases that have complementary strengths and limitations, and find replication across them,” Simmering mentioned.

The analysis workforce had earlier discovered that terazosin might forestall or sluggish Parkinson’s illness in animal fashions.

Tamsulosin didn’t have the identical mobile power manufacturing as terazosin. That enhanced mobile power manufacturing is vital in terazosin’s protecting impact, in response to the research. This protecting impact elevated the longer the drug was used.


More persons are being recognized with Parkinson’s illness than will be defined by a rise within the getting older inhabitants, Simmering mentioned. Parkinson’s illness impacts about 1% of the inhabitants above age 60, making it the commonest neurodegenerative illness after Alzheimer’s. Genetics account for about 10% of Parkinson’s circumstances.


James Beck, chief scientific officer on the Parkinson’s Foundation, cautioned towards considering this analysis would result in a speedy resolution to Parkinson’s illness.

“People aren’t going to go and take these drugs with the hopes that it’s going to stop or cure or prevent Parkinson’s disease. But that’s never really the purpose, as we’ve talked about before, with epidemiology studies,” Beck mentioned. “It provides this guiding light for scientists to really be able to follow up and understand why they see something at a population level.”

Beck mentioned the research is a part of a line of analysis that hypothesizes that remedies might assist with glycolysis, which is a part of the power metabolism inside a cell. For this purpose, generally individuals will describe neurodegenerative illnesses like Alzheimer’s or Parkinson’s illness as “type 3 diabetes,” Beck mentioned.

“We still don’t get what causes Parkinson’s at all. We still don’t know how to cure it, 80% or 85% of people who develop Parkinson’s disease, we don’t know why they develop their disease,” mentioned Beck, who want to see additional analysis.


The analysis was partly funded by the U.S. National Institutes of Health and revealed on-line Feb. 1 in JAMA Neurology.

Though this preliminary research didn’t embrace ladies as a result of far fewer ladies take the remedy, it’s a drug that ladies can take and have taken for hypertension, Simmering famous.

The draw back of the remedy is that it could decrease blood stress too far and sufferers can change into hypotensive, Simmering mentioned, and folks with Parkinson’s already are liable to turning into hypotensive.

There could also be a future trial. That would wish to start out by exhibiting security and efficacy, together with for this challenge, he mentioned.

“We know it’s reasonably safe, but it’s always a concern,” Simmering mentioned.
