Sildenafil is a drug used to treat erectile dysfunction and pulmonary arterial hypertension.
It works by increasing blood flow to the penis to help men achieve and maintain an erection. The drug is also used to treat benign prostatic hyperplasia, a condition in which the prostate gland enlarges and causes urinary problems such as difficulty urinating. Other uses of Sildenafil include treating other conditions, such as pulmonary arterial hypertension (PAH), pulmonary arterial hypertension (PAH-PA), or high blood pressure in the lungs, among others.
Sildenafil is a type of drug called a phosphodiesterase type 5 (PDE 5) inhibitor. It works by blocking an enzyme in the body called PDE 5 that promotes blood flow to the penis. This allows blood vessels in the penis to widen and allow blood to flow more easily. This increased blood flow helps men achieve and maintain an erection when sexually aroused.
Sildenafil is usually taken as needed. It does not work if you are not sexually aroused. It is typically taken once or twice a day, but you can take Sildenafil with or without food.
You can take Sildenafil with or without food. It's recommended to take it with or after a meal.

Rest assured that each order is authentic and processed according to Amazon's or your local laws.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.
Sildenafil, the active ingredient in Viagra, is the product of a chemical interaction called guanylate cyclase- thereby. Viagra blocks 50% of the enzyme that’s supposed to be in working with your blood vessel lining to take back some of the extra blood flow during sexual arousal.
When blood flows to and out of your penis, tadalafil, the active ingredient, it activates a protein that turns testosterone into C 7502.
That increase in testosterone can lead to an erection that lasts longer. Viagra therefore activates an enzyme called Sildenafil, which helps to increase blood flow to and from your penis during sexual stimulation.
While Sildenafil’s effects on testosterone are generally considered reliable, they aren’t what make Viagra a PDE5 inhibitor.
In fact, Sildenafil’s main active ingredient, Sildenafil Daily, can slightly raise your blood pressure by as as much as 100-percent. When you’re stress-stricken, for example, you may be more likely to get angina than to have a heart condition. So Sildenafil can help lower your blood pressure more than Viagra does— possibly more significantly, making it a good choice for women who are at risk for heart disease.
However, Sildenafil is not the right ED medication for women who are experiencing erectile dysfunction. In fact, it can be an issue for men who take nitrates, as it can lead to a dangerous drop in blood pressure.
Viagra, which is offered in two dosage strengths (25mg and 50mg, is intended to be taken on an as-needed basis before you have sex), contains as its active ingredient 20-30% of the recommended dose. That’s because Sildenafil, the other ED medication, about 80% of what’s needed, it also retails at 40p per day.
If you’re a women who’s interested in trying Viagra, we invite you to. If you’re here for PDE5 inhibitors because of that reason, we encourage you to buy Viagra online today.

Viagra and Sildenafil are essentially the same medication. Viagra—which is why it’s so popular today—is considered a PDE5 inhibitor since it has a retinaster system. Whereas Sildenafil has a similar mechanism of action, it’s only been approved by the Food and Drug Administration for treating pulmonary arterial hypertension (PAH).
When you take Viagra, your body naturally converts it to Sildenafil. That’s because Sildenafil also retails at 40-percent of the recommended dose. So if you take Viagra regularly, you’ll only need about a one-hour take to kick in. That’s great for that extended window of opportunity for sexual activity.
