Sildenafil is a chemical created decades ago to improve the nutrition of the heart muscle. However, in the course of research, another effect was discovered that unexpectedly surprised scientists. Reception of sildenafil influenced an increase in blood flow to the genitals, in particular, to the penis. As a result, this drug has found its alternative use. It is worth adding that the effect of the drug as an aphrodisiac and pathogen is much more effective than in the form of an additive to improve the circulation of the myocardium, dozens of times. Consequently, sildenafil as a means of treating the heart muscle did not meet expectations, but it was firmly and permanently entrenched in the market of pathogens and drugs for the treatment of erectile dysfunctions.
The first company to patent this chemical element in the form of a finished product was Pfizer. Many people know this supplement called “Viagra” that was the name she was given. In a short period of time, the American product became the most sold aphrodisiac in the world, which found its popularity even in the most remote corners of the globe.
Sildenafil was first opened in 1992, and since then has continued to be produced even in our time. Most often represented in the compound “citrate” (Sildenafil citrate), as it is the most easily absorbed by the body form.
Types of drugs
Sildenafil citrate is most often produced in the form of blue tablets, less often in the form of gum. Tablets are more convenient to swallow, but since they have a bitter taste, in some cases it is more pleasant to eat chewing gum, which, moreover, is absorbed faster because the mouth already chews to smaller sizes, which improves its absorption in subsequent stages of digestion. . But chewing Viagra is much more expensive than pill.
The most common dosages are 25, 50, 100 mg. Original drugs are usually produced in blisters of 4 tablets. Generics, that is, copies with exactly the same active ingredient but from another manufacturer, may have large dosages of 150-200 mg.
Original Viagra is much more expensive than generics, but it has a stable quality and a controlled price. Production of copies is usually not checked by anyone, so most often they are of low quality. Sometimes come across good products from bona fide manufacturers. In any case, the choice is always left to users. Stable quality and high price, or low price and experiments with the search for working drugs.
Mode of application
The drug should be taken in dosages from 50 to 100 mg at a time, 20-30 minutes before the intended sexual contact. Or as prescribed by the attending physician. Wash down the pills with plenty of liquid.
The period of action of the substance is 4-6 hours.
Possible side effects
Like any other active chemical, sildenafil has a number of side effects. To which can be attributed:
- headache, most often manifested the day after use;
- redness of the face;
- change the color palette of view (can only be observed in people with diseases of the retina of the eyeballs).
The most common is dizziness, which most often occurs in people with poor health and a physically unprepared body. In healthy, sports users, negative effects are usually absent.
You should also avoid taking the drug to persons under 18 years of age. And be sure to follow the recommendations in the instructions for the drug used, you can protect yourself from possible problems.
In addition, although some stores claim that Viagra can be combined with alcohol intake, we strongly advise you not to do this, because in this case the load on the heart increases.
