Viagra – a Bit of History
Viagra is the best known medicine for treating erectile dysfunction of various etiology in men. Its effect is based on the ability of its active substance of Sildenafil citrate to dilate blood vessels in male genital organs.
Viagra is used only in men. This medicine for males has proved to be very useful in the treatment of erectile dysfunction (ED), especially of the cases of impotence associated with problems with blood flow in genitals.
A considerable merit of Viagra is that due to this drug the intimate issue of erection problems has become widely discussed among doctors, pharmacists, and, what is the most important, among ordinary men and in their families. Earlier the words “erectile dysfunction” could be pronounced only in a purely scientific field.
Originally sildenafil citrate had to cure pathological conditions of the heart like angina pectoris. When the newly synthesized drug was being tested on volunteers, men discovered that heart practically wasn’t influenced by the drug, but it had a great effect on male power: increased potency, improved erection, longer and better sexual acts. Of course, scientists of an American pharmaceutical company “Pfizer” could pass by these facts. Quite soon a new drug against male problems in bed was introduced on the market, named Viagra.
What Happens With Your Penis After Taking Viagra?
Viagra contains sildenafil citrate, which inhibits the enzyme PDE-5. Blocking of this enzyme relaxes the cells of smooth muscles which are present in the walls of blood vessels. The maximum effect of dilated blood vessels is pronounced in cavernous bodies of the penis, letting them get filled with a larger amount of blood than usually. Increased blood flow in the penis in the presence of sexual stimulation helps a much stronger erection to occur.
Warning! Without sexual stimulation and the presence of sexual desire, erection won’t occur. Viagra doesn’t help when there is no sexual attention at all.
When to Take Viagra?
In different men, Viagra starts acting after different time, because men differ in overall sizes and metabolism. Already about fifteen minutes after taking Viagra you can notice that you need less stimulation to achieve erection.
Still, usually it is recommended to take Viagra at least half an hour before planned sex. Some men prefer to take the pills even an hour before starting the sexual intercourse. This term is recognized as a “peak” of the action of the drug, when its concentration in blood reaches maximum. The total period of action of Viagra lasts several hours, in the average reaching three of four hours of increased sexual sensitivity.
Everything said above extends also to generic Viagra. And here comes a new question: does generic Viagra really work?
Does Generic Viagra Work?
To answer this question, we need to figure out what is generic Viagra. Opening the dictionary, we will learn that generics, or analogues, are generic (analogue) medicines towards the original ones. Generics contain the same active substance and its dosage, but auxiliary substances in them can differ. The names of generics are also different from the original ones, because their manufacturers have no right to use the names of the original medicines. Purification of the generic medicine can be worse than the purification of the original one. Therefore, some people prefer to buy only patented drugs by the original manufacturer.
In spite of these facts, some kinds of generic Viagra have proven to be quite effective, well-purified and profitable. They are cheaper and at the same time not less effective than the original Viagra by Pfizer. Among them Canadian Generic Viagra can be emphasized – this generic of famous “blue pills” is one of the most popular in our online pharmacy.
Dosage of Viagra for Treating ED
Viagra is most often prescribed in the dosage of 50 mg. This amount of sildenafil citrate is enough for most men to achieve a sufficient erection. Sometimes the dosage of 25 mg is enough, and seldom 100 mg is prescribed. Still, such a big dosage can be hard to tolerate, and side effects can be pronounced more brightly.
Before purchasing Viagra in any dosage, you should visit a doctor and get his prescription for the medicine. A medical examination is also necessary.
Viagra is contraindicated in men suffering from heart diseases, because this drug has an effect on cardiovascular system. Sometimes in media appear horrible stories about men dying from Viagra, but they are not true: absolute number of sudden deaths because of heart attacks relate to the men who already had heart problems.
Be careful with magic blue pills for men if you have high arterial pressure. Disorders of cerebral circulation are absolute contraindications of Viagra, as well as anatomical deformations of the penis. Men under 18 years old must not use Viagra. For women there is no sense in buying this medicine at all, because it was developed specially for men’s organism.
