A new health benefit of Viagra
A recent study found that using Viagra, known to treat erectile dysfunction
may have a new and unexpected health benefit.
The researchers showed that sildenafil, the active ingredient in Viagra, contributes
to stimulating human stem cells to transform into cells responsible for building
bones, which enhances skeletal regeneration and maintains its density, and thus
helps in strengthening bones and preventing their fragility with age.
The study showed that :
the human skeleton is completely renewed almost every ten years, but with age
the body’s ability to produce new bone decreases, and it begins to lose bone mass
which increases the risk of fractures and osteoporosis.
A team from Peking University conducted laboratory experiments on mice
and the results showed that taking sildenafil contributed to preventing bone loss,
which opens the door to its use as a potential treatment for osteoporosis.
"The results showed that
sildenafil promotes the differentiation of stem cells into
bone cells and prevents bone loss, which may be of real therapeutic benefit in
the face of osteoporosis," said the researchers, Dr.Minglong Hu and Dr.Likun Wu.
The researchers pointed out that adopting completely new drugs requires years of
experimentation and costs, while sildenafil is an approved and safe drug, which
makes it a good candidate for reemployment in this field.
It is worth noting that
Viagra was originally developed in the 1980s to treat heart disease, before its
effective effect in treating erectile dysfunction was discovered, and since then
its name has also been associated with studies indicating
its potential role in reducing the risk of dementia.
