Viagra, also known by its generic name sildenafil citrate, is a medication used to treat erectile dysfunction (ED) in men. ED is a condition where a man is unable to achieve or maintain an erection sufficient for satisfactory sexual performance. Viagra works by increasing blood flow to the penis, allowing men to achieve and maintain an erection when sexually stimulated.
Viagra was first approved by the U.S. Food and Drug Administration (FDA) in 1998 and has since become one of the most widely recognized and used treatments for ED. The medication is available in various strengths, including 25mg, 50mg, and 100mg tablets, and is typically taken orally 30 minutes to 1 hour before sexual activity. The effects of Viagra can last for up to 4 hours, although this may vary from person to person.
How Viagra Works
Viagra works by inhibiting the action of an enzyme called phosphodiesterase type 5 (PDE5), which is responsible for breaking down a chemical called cyclic guanosine monophosphate (cGMP). cGMP is a key player in the process of achieving an erection, as it helps to relax the smooth muscle in the blood vessels of the penis, allowing blood to flow in and fill the penis. By blocking the action of PDE5, Viagra allows cGMP to build up and persist, leading to improved blood flow and a stronger erection.
Safety and Efficacy
Viagra has been extensively studied in clinical trials and has been shown to be safe and effective in treating ED. The medication has been tested in thousands of men and has been found to be well-tolerated, with common side effects including headache, flushing, and indigestion. However, as with any medication, there are potential risks and interactions to be aware of, and men should consult with their doctor before taking Viagra, especially if they have any underlying medical conditions or are taking other medications.
| Viagra Dosage | Recommended Use |
|---|---|
| 25mg | Mild ED, men with certain medical conditions |
| 50mg | Most common starting dose, men with moderate ED |
| 100mg | Men with severe ED, or those who do not respond to lower doses |
