Viagra and erectile dysfunction

The erectile dysfunction medication may help defend against lung problems resulting from elevated altitudes. Elevated altitude can sometimes cause sickness, especially in people with existing ticker and lung problems. The thinner air or want of oxygen at higher altitudes can cause blood vessels to constrict. When this occurs within the lungs, the constriction of blood vessels can put more power on the nerve, important to existence-menacing pump failing. The higher altitude can cause blood vessels in the lung to leaking liquid and construct up in the lung, interfering with oxygen interchange.

Viagra works by relaxing blood vessels, allowing more blood to stream candidly through vessels. The researchers used this medication to block the effects of tall altitude on blood vessels on the lung. They looked at whether the use of Viagra would help the lungs carry on to get oxygen while ascending to higher altitudes.
In a late test, Viagra was better than a placebo at protecting men's lungs. This was no normal lab exam. Instead, 12 men perched on a French mountain about 2.7 miles (4,350 meters) above sea uniform, pushing their lungs to the limits in the name of information. The participants were normal, in good men around 29 years old. They weren't mountaineers. None was used to elevated altitudes.
