Viagra works by relaxing muscles found in the walls of blood vessels, spanish gold fly thereby increasing blood flow to specific areas of the body. In the context of ED, this increased blood flow is directed towards the penis, helping men achieve and maintain an erection.

The process begins with the release of a protein called cyclic guanosine monophosphate (cGMP). This protein causes more blood to flow into the penis, leading to an erection. However, another protein called phosphodiesterase-type 5 (PDE-5) breaks down cGMP, stopping the erection. In people having difficulty with erections, PDE-5 may work too quickly. Viagra blocks PDE-5 from working, allowing blood flow to the penis to occur and not be stopped by PDE-52.

Viagra is typically taken as needed to treat ED in adults. It works quickly, often within an hour of being taken, and can begin working within 30 minutes. The drug is most effective about one hour after it’s taken.

However, Viagra should not be used without caution. Some medicines can cause unwanted or dangerous effects when used with Viagra. For instance, it should not be taken if you are also using a nitrate drug for chest pain or heart problems. Taking sildenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
