What Is Viagra And How It Acts?
It is not a secret that almost every adult man has heard about such a medicine as Viagra. This is a famous drug for the treatment of erectile dysfunction in men of different age and with different problems.
Original Viagra is manufactured by an American pharmaceutical company Pfizer, which is one of the largest manufacturers of drugs in the world. Viagra was synthesized in the early 1990s, when the scientists discovered unique properties of sildenafil citrate – the active substance that was intended to be used in patients with angina pectoris and pulmonary hypertension. Occasionally, the newly invented medicine turned out to be not effective in regard of these diseases, but had other great effect: on the mechanism of erection. After a series of thorough scientific and clinic researches the drug entered the pharmaceutical market under the brand name of Viagra.
Of course, it is interesting how such a famous drug works, why is it so popular among thousands of men, if not to say millions.
Sildenafil citrate, which is the active substance of Viagra, reaches the effect of a radically improved erection through dilating blood vessels, especially in the genital organs of a man. In the penis there are cavernous bodies, which are particularly sensitive to sildenafil. As a result of dilated blood vessels, they get filled with a much larger amount of blood, which leads to a strong and stable erection. It is important to mention that erection doesn’t appear if a man has got no sexual desire and sexual stimulation: it is not a magic pill, although sometimes men call it so.
Original Viagra by Pfizer is sold in the form of blue diamond-shaped pills with an inscription “Pfizer” on one side and “VGR 50”, “VGR 25” or “VGR 100” on the other one, depending on the dosage of sildenafil citrate in one pill.
Generic Viagra in Canada
In Canada, as well as in a number of other countries, the patent for Viagra was issued in 1998. Since 2012, the patent protection is canceled in Canada by court, because Pfizer violated legislative norms, not disclosing the information about the active substance of drug. Because the patent was cancelled, Canadian pharmaceutical companies had the possibility to start producing generics of Viagra earlier than the concerns of other countries. It in Canadian pharmaceutical market are one of the best generics of this drug.
What Are Generics of Viagra?
Some may ask, why is it profitable to manufacture and sell generic medicines, when the original ones are anyway better known, more popular and more reliable? We will try to answer this question.
First of all, money rules the game. Yes, generics are cheaper and thus bring less profit to their manufacturers, but at the same time the manufacturing companies don’t have to spend money, time and huge resources on advertising, public relations and promotion campaigns. Second, important discoveries in pharmaceutical industry happen rather seldom, and manufacturers can’t always do nothing except conducting scientific studies and researches, taking into account that a discovery can never take place, and all the efforts will be in vain. Third, have you ever wondered what would happen if only the company which originally synthesized a drug would have the right to sell it? We wouldn’t be able to find even simple aspirin in our drug stores, or it would be damn expensive.
In this way, it is very profitable to produce and sell generics, and it brings real help to many patients all around the world.
It is important to remember that generic medicines are not counterfeits, they are the same medicines as the original ones, with the same active substances and their dosage, just under another names, produced by other companies, and perhaps having other auxiliary substances in their composition.
