The History of Viagra

In the 90s of the 20th century, American scientists were engaged in the invention of a new generation drug that was supposed to cope with chest pain in patients with stenocardia. However, clinical trials revealed that the active substance Sildenafil citrate did not produce any effect on the heart. At the same time, all men who participated in the research started enthusiastically talking about side effects of Viagra associated with an improved erection. When most of the participants of the experiment has finally refused to return the useless pills for the heart, and one even tried to get into the laboratory to get more pills, the company’s managers realized that created a “gold mine”.

The new miracle pills have been given a name basing on the words “Vigor” (means “power” or “strength”) and Niagara (Niagara Falls), which is the biggest waterfall in North America.

Since 1993 scientists have been conducting a long and complex investigation, the aim of which was to confirm the unique features of Sildenafil. As a result, they proved not only the high efficiency of the drug but also the safety of tablets in the fight against male erectile dysfunction. As a result, the Department of the United States for the control of drugs has permitted the release of Viagra for men.

How Does Viagra Work?

Feel your power!The main mechanism of Viagra action is a significant increase in blood flow into the penis, which provides the natural erection. This drug has a positive effect only on a natural mechanism of male erection – that is the novelty and the secret of the huge popularity of the ED drug.

Sildenafil is NOT a stimulator that increases male libido, and does NOT create a sexual desire – the action of “magic” pills is based only on the local increase in blood flow to the penis, which provides a natural erection.

How Does an Erection Occur?

The start of the erectile process is the presence of sexual arousal. When a man is sexually excited, the blood vessels located in the pelvis, are expanding, thus providing a high blood flow to the penile area, the penis increases in size and hardens. That is how an erection occurs. When the sexual act is completed with the release of sperm, sexual tension disappears, accompanied by a decrease of blood flow in the penis, and the penis gets into its natural usual state.

Under the influence of adverse factors such as chronic pathological conditions or long-term therapy with drugs of antihypertensive action, a man may experience a violation of blood flow in the penis. This results in the lack of proper blood flow to the penis when a man is sexually aroused. So, the erection is insufficient or absent at all what prevents to perform sexual intercourse. If such a failure occurs repeatedly for a long time, experts call it erectile dysfunction.

Effects of Viagra

The action of this ED drug from Canadian Pharmacy is very simple. To understand how it works, you just need to know the mechanism of a natural erection mentioned above. The natural erection is absolutely necessary for proper sexual intercourse. Viagra does the same things as nature does, everything is quite natural and safe. However, you have to remember that these pills do not affect sexual desire and do not increase libido, a man should be excited and really want intimacy.

How To Take Viagra?

Before taking Viagra, you need to see a doctor first, as only a doctor can reveal erectile dysfunction causes, the disease which interferes with man’s normal erection and prescribe the necessary drug, taking into account all the features of your organism. The rest actions are very simple and standard: it is necessary to take one pill about 30-40 minutes before the planned sexual intercourse and take some water after. Take the drug only once per day, do not exceed the prescribed dosage. The normal daily dose of the drug is 50 mg, but it may be decreased or increased by the doctor. In case of overdose, you can have a negative reaction to your health. Theoretically, sildenafil and alcohol can be combined but the drug’s effect will be reduced.

Active Ingredients of The Drug

Do not take the drug without consulting a doctor, because it can be dangerous. The active ingredient of the ED drug is Sildenafil citrate. This component has an ability to instantly interact with many drugs. The leaders are the medicines used in the treatment of cardiovascular pathologies and nitrates. If you combine them with sildenafil, you may experience all sorts of complications.

In general, the drug produces a very positive effect on the male body, this has been proven in clinical trials. Most men participating in the researchers (≈80%) got a hard and long-lasting erection after taking this drug, they also experienced a feeling of profound satisfaction after the remedy ceased to work. Approximately 15% of participants noted the lack of effectiveness of the PDE-5 inhibitor, the remaining minority of men (5%) said that the Viagra effects can be dangerous for health.

When is This Drug Useless?

These ED pills will not help men who have difficulty with sexual desire. Viagra as well as Cialis, Levitra, and generic drugs block the enzyme phosphodiesterase type 5, increasing the blood flow to the penis and providing an erection. This means that the erection improvement is observed only in those men who have problems with potency, but not with sexual desire. If a man has no desire to have sex, no magic pills can help.
