Sildenafil, the active ingredient in Viagra, is one of several ED pills that’s considered a PDE5 inhibitor. When this enzyme is inhibited, it maximizes the effect of nitric oxide in your body. (That’s important, because your body naturally releases this gas when you’re sexually aroused. So it’s key to the process of getting and maintaining an erection.)
With more nitric oxide in play, the muscles around your penis can relax. In turn, blood flow to your penis improves. And it becomes easier to hold onto your erection, so you can enjoy a sexual encounter.
Sildenafil also works quickly. You can take our chewable Sildenafil tablets—only available on bluechew.com—about one hour before sex. Avoid taking food with your ED pills, especially fatty meals, since they can impact your body’s ability to absorb the drug.
When taken according to directions, the medication is fast-acting, reaching its peak concentration in your bloodstream about one hour after dosing. Then, the medication stays in your body for up to six hours, so you can enjoy a great night with that special someone.
