Viagra, also known by its generic name sildenafil, is one of the most well-known treatments for erectile dysfunction (ED). Originally developed as a treatment for high blood pressure and angina, it was discovered that the drug had a significant effect on increasing blood flow to certain areas of the body. This discovery led to its approval as a treatment for ED in 1998 by the U.S. Food and Drug Administration (FDA).
Viagra works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). This enzyme is responsible for breaking down cyclic guanosine monophosphate (cGMP), a molecule that helps relax blood vessels and improve circulation. By blocking PDE5, Viagra allows cGMP levels to remain high, leading to improved blood flow to the penis and facilitating erections in response to sexual stimulation.
It is important to note that Viagra does not cause automatic erections; rather, it enhances the body’s natural response to arousal. It typically takes about 30-60 minutes to take effect and lasts for approximately 4-6 hours. Side effects may include headaches, flushing, indigestion, nasal congestion, and dizziness. It is always advisable to consult a healthcare professional before using Viagra, especially for individuals with underlying health conditions. Report this page
