Viagra is a well-known medication, primarily used to treat Erectile Dysfunction (ED). It contains the active salt Sildenafil and is prescribed when someone is unable to achieve or maintain an erection sufficient for sexual activity. <\/p>\n\n\n\n

For men with ED, Viagra helps improve blood flow to the penis when sexually aroused. It stops the natural enzyme, PDE5, that reduces blood flow, allowing the blood vessels to stay relaxed and open. <\/p>\n\n\n\n

Viagra does not cause an erection on its own. It also does not treat the underlying causes of ED, like health problems or stress. This article explains how Viagra works, how to use it safely, the side effects you should know about and how it fits into your overall sexual health care.<\/p>\n\n\n

What does Viagra do<\/h2>\n\n\n

Viagra<\/a> helps men with ED by targeting an enzyme called Phosphodiesterase type 5 (PDE5). This enzyme usually breaks down a chemical messenger in your body called cyclic Guanosine Monophosphate (cGMP).<\/p>\n\n\n\n

During sexual arousal, cGMP sends signals to blood vessels in the penis to relax and widen, which allows more blood to flow in and create an erection. If your body does not produce enough cGMP, this process is cut short, making it difficult to achieve or maintain firmness.<\/p>\n\n\n\n

By blocking PDE5, Viagra keeps cGMP active for longer, making erections stronger and easier to maintain when sexual stimulation is present.<\/p>\n\n\n\r\n
