Viagra, a drug that has the generic name sildenafil, helps increase blood flow to the penis so that its owner can maintain an p.

But did you know that this popular drug was created by accident? In the beginning, Sildenafil was in the testing phase of a drug to cure angina (sitting wind) the condition of narrowing of the arteries in charge of supplying the heart with blood. thanks to its effects that relax blood vessels. In the process, finally the blue pill that we know so far was formalized as an anti-impotence drug.

To understand more about how Viagra works, it's a good idea to first understand how you can (and don't) get an erection.

The mechanism of the penis reaches an erection

reported from the page https://s.id/9b7Gn - Try moving one part of your body - blink, for example, or stick out your tongue. When you move almost every part of your body, you do it with muscles. You think about moving it, the muscles in question will contract, and the limbs you need will move. In contrast to the penis. There is no muscle contraction involved in making the penis erect. To make your genitalia "stand", the penis uses pressure.

In short, to get an erection, you need three things: healthy blood flow, a healthy nervous system, and sexual arousal (libido). If the blood flow that leads to the penis does not work properly, for example if the inlet of the blood (arteries) is too narrow or if blood flows too fast through its exit gate (vein), you might have difficulty reaching or maintaining an erection. Blood flow problems, in addition to other medical and psychological conditions, are a major cause of erectile dysfunction (impotence).

How does Viagra work to treat impotence?
Viagra works by inhibiting PDE-5, an enzyme produced after sex is over and makes the penis wilt. This makes the muscles in the penis more likely to relax and allow blood to flow in, causing an erection.

Sildenafil citrate, contained in Viagra, acts as the main active component in charge of pirating the performance of PDE-5 and deactivating the enzyme. When a man takes a blue pill, sildenafil citrate flows throughout the body, but it only affects the enzyme PDE-5 in the penis.

Once PDE-5 is blocked, a compound called cGMP can gather in the penis and increase blood flow to the penis, without affecting other parts of the body (Note: PDE has many kinds, but PDE-5 is the enzyme that is most commonly found in the penis). That is, the greater the number of cGMP, the faster the blood flow. The more rapid blood flow to your penis, the greater the erection rate.

It is important to understand that taking Viagra tablets alone will not cause an erection. Viagra must be consumed in combination with some form of sexual stimulation (visual, touch, or both) for an erection to occur. Without sexual stimulation, Viagra will not have any effect. Viagra works best if consumed 30-60 minutes before sexual activity.

How long can Viagra maintain an erection?

Only 1 tablet should be used in one day, and on an empty stomach. Increasing Viagra dosage beyond the recommended amount will not increase response, and will only increase the risk of dangerous side effects.

The duration of erection can last after using Viagra varies depending on the user (based on age, diet, alcohol consumption, dosage, health conditions, and drug interactions). But in general, Viagra can maintain an erection for up to 4-5 hours after use coupled with sexual stimulation.

On the other hand, most men find that the effect of this magic blue pill will start to fade within 2-3 hours after the first consumption.

The drug will remain in the blood for about four hours, and then it will be rinsed clean of your circulatory system by the liver and kidneys.

You may or may not consume Viagra

In general, Viagra works effectively up to 65-70% in all impotent men.

The thing to remember, this pill may not be strong enough for those who have too severe arterial narrowing.

In addition, because Viagra works similarly to drugs containing nitrates, it is not recommended for men who take nitrate drugs for heart disease, or those with certain other heart conditions to take Viagra. In some men, this drug causes a bad headache.
