How many men take viagra? Study says drug cuts Alzheimer's risk
Viagra has long been used as a helping hand in the bedroom and as a way for men to treat erectile dysfunction – but a new study has found that it could reduce the risk of developing Alzheimer’s disease too.
The large-scale study, published in the journal Neurology, followed 269,000 men with erectile dysfunction and an average age of 59 over a five-year period and compared results of the 55% of the cohort who were prescribed viagra and the 45% who were not.
It found that those taking viagra were one fifth (18%) less likely to develop Alzheimer’s disease than those who weren’t on the medication.
"These results are encouraging and warrant further research, which is needed to confirm these findings, learn more about the potential benefits and mechanisms of these drugs, and look into the optimal dosage," Dr Ruth Brauer, of University College London, says.
"A randomised, controlled trial with both male and female participants is warranted to determine whether these findings would apply to women as well."
The researchers are not clear on why the drug can help prevent the memory disorder and say further studies are needed.
What is viagra?
Viagra is a drug that is primarily used to treat erectile dysfunction, which is a common condition that sees men struggle to get and keep an erection.
It can also be used to treat pulmonary hypertension, which is high blood pressure in the blood vessels that supply the lungs.
Viagra works by dilating blood vessels to allow more blood to flow through to the penis, and men can take it up to four hours before they want to have sex. The NHS states that it won’t work on its own, and that men have to be sexually excited to see results.
