Erectile dysfunction medicine comparable to Viagra might be inadvertently chopping the probabilities of males growing Alzheimer’s illness, analysis suggests.
Alzheimer’s Research UK referred to as the findings “encouraging,” saying the prospect of repurposing medicine to deal with the situation may assist “accelerate progress and open up new avenues to prevent or treat dementia-causing diseases”.
However the charity stated extra analysis is required to verify the outcomes and look at the influence the medicine may have on girls and others.
In the examine, printed within the journal Neurology, University College London (UCL) consultants examined the medical data of 269,725 males aged over 40 – with a mean age of 59 – who have been identified with erectile dysfunction between 2000 and 2017.
More than half of these sampled had been prescribed a sort of medicine generally known as a PDE5I drug (phosphodiesterase sort 5 inhibitors), which incorporates Viagra, Cialis, vardenafil and avanafil.
