Sildenafil is a type of drug called a PDE5 inhibitor. PDE5 inhibitors work by blocking an enzyme called PDE5 (phosphodiesterase type 5), which in turn temporarily relaxes blood vessels and improves blood flow to the penis during sexual stimulation. For men who have trouble getting or staying hard, PDE5 inhibitors like sildenafil are typically the first line of treatment for erectile dysfunction.
Sildenafil citrate is a well-known PDE5 inhibitor proven to treat ED, which doctors started prescribing ever since Viagra got its FDA approval. Long story short, Sildenafil makes it easy to get hard right when you need it. Sildenafil typically lasts for at least four and up to 8-12 hours, but its effect is strongest 2-4 hours after it’s taken. As the amount of sildenafil in the blood stream drops, so do the effects. You should not experience erections that won’t go away. If you have an erection that lasts more than 4 hours after taking sildenafil, get medical help right away. Viagra is the brand name of the ED medication invented by Pfizer. Sildenafil (citrate) is the active ingredient that makes Viagra effective in treating ED. The main difference lies in brand and price. You should take Sildenafil as prescribed. Usually, that means taking it on an empty stomach, an hour before intercourse. You’ll have plenty of time to get in the mood and even more time with strong erection when you need it the most. Life’s too short of accepting having average sex. Sildenafil was found to improve erections in about two-thirds of men, according to a CLINICAL STUDY. If sildenafil does not work, it may be because it wasn’t taken soon enough before engaging in sexual activity, it was taken with food, or that the dosing is incorrect.
