Viagra is one of the most famous drugs in the world, and since it entered our lives about thirty years ago, it has made a real revolution in everything related to the phenomenon of male impotence. If in the past it was a phenomenon that led to shame and frustration, then thanks to Viagra the situation today is completely different. So why do you need Viagra, and what is important to know before buying this medicine? We will try to explain.
Towards the end of the 1980s and the beginning of the 1990s, the international pharmaceutical company Pfizer began to try to develop a new drug designed to dilate blood vessels and lower blood pressure. The same drug, whose generic name is sildenafil, did show considerable effectiveness in performing its original function - but apart from this function, male experimenters reported that it had a significant side effect that had not been observed before, when taking it led to the formation of a prolonged erection, even in experimenters who suffered from impotence.
After being approved through the American and international health authorities, the drug began to be marketed under the name Viagra, when most of those who take it today do so in order to treat situations of impotence.
To understand why it is necessary Viagra, one must first understand the dimensions of the phenomenon of male impotence. The main symptom of this phenomenon, which is the inability to achieve an erection or the inability to maintain this state throughout intercourse, is a condition that approximately 75% of all men will suffer from at one point or another in their lives.
A lower percentage, but still a significant percentage, suffer from a state of general impotence, which is defined as such when suffering from these symptoms for at least three months. The causes of impotence can be many - starting from factors related to blood flow to the penis, through chronic diseases such as diabetes, and ending with mental and social factors. For all these situations together, Viagra is an excellent solution, since its action helps in many situations of impotence, which are caused by many factors.
After we understood why Viagra is needed, we need to understand what exactly it does. Viagra is a drug whose original action was, as mentioned, to widen blood vessels by relaxing the smooth muscle lining the blood vessels, an action it achieves by inhibiting an enzyme called PDE5. The action of the drug in the genital organ is achieved due to the fact that the erection itself is a phenomenon that occurs due to increased blood flow to the genital organ in situations of sexual stimulation, and the blood vessels leading to the genital organ are particularly sensitive to the action of the enzyme inhibited by the drug.
Thus, taking it leads to an erection in sexually stimulated situations, starting half an hour after taking it and about 12 hours later. The drug is suitable for men suffering from sexual dysfunction, usually regardless of the cause of those problems. It is important to note that anatomical problems that do not allow the creation of an erection or ejaculation - are not solved by Viagra, and it is important to perform a comprehensive examination by a doctor before starting to take it.
The most common side effects of Viagra are flushing and headaches. Apart from this, there may be dizziness, changes in the digestive system, rashes, a feeling of heat and other symptoms - so you should consult a doctor before use. Another thing that is important to know is that the combination of Viagra with nitrate-type drugs (nitroprusside or nitroglycerin), given in certain hypertensive conditions, is fatal and one should be informed about taking any of these drugs in hospitalization situations or receiving other medical treatment.
In the past, a state of impotence was a state that left the sufferer completely helpless. Today, thanks to drugs like Viagra, this is a very effectively treatable phenomenon - which significantly improves the quality of life, and can provide many more years of healthy and satisfying sexual activity.
