Sildenafil, widely known as “Viagra,” is primarily used to treat erectile dysfunction. However, new research suggests it may have an unexpected role in treating Leigh syndrome, a rare and severe condition affecting children.
A study published in the journal Cell reports noticeable improvement in patients with Leigh syndrome after using sildenafil. This genetic disorder disrupts mitochondria -- the energy-producing parts of cells -- mainly impacting the brain and muscles. As a result, children often experience muscle weakness, seizures, movement difficulties, and complications such as retinitis pigmentosa, lactic acidosis, and hypoglycemia.
Researchers observed significant health improvements in affected children treated with sildenafil. The drug is known to enhance blood circulation, which may help improve cellular energy production. It may also support nerve cell growth, offering further therapeutic benefits.
These findings highlight the potential of repurposing an established adult medication for serious pediatric conditions, offering new hope for children suffering from this life-threatening disorder.
