Medicines for erectile dysfunction. Effects of Viagra and its generics
Viagra and its generics (Cialis and Levitra) are the main medicines are for the treatment of erectile dysfunction, which, according to the pharmaceuticals, are very similar to each other. However, they compete against each other in advertising campaigns.
Viagra, Cialis and Levitra belong to the PDE5 inhibitors, which prevent the vasodilation of the penis, and improve erection. Viagra and Levitra have almost the same ingredients and characteristics, while the structure of Cialis is slightly different. You can buy these drugs on kamagraperth.com.
Actually, the major difference between these medicines is that Levitra absorbs faster, and Cialis outputs slower. That means that the effect of all PDE-5 inhibitors is almost the same. It varies only in time of beginning and duration of action.
At the beginning, these drugs were prescribed only to the people suffering from severe impotency, caused by such diseases as diabetes, neurological diseases or side effects of antidepressants. But later Viagra became more and more popular among all kinds of people. At first, doctors started to prescribe it to all patients who have any sexual problems. Then there were the numerous online pharmacies offering to buy the drugs for erectile dysfunction over the counter, and even with delivery.
Therefore, the range of buyers has increased. The so-called “patients” only wanted to be enough confident before an important date.
Basically, the three above-mentioned drugs can be purchased by everybody who wants to improve their sexual opportunities. Producers of drugs claim that food and alcohol don’t affect their efficiency.
How would you imagine a general image of the consumer of Viagra? According to the doctors, the main consumers of australian Viagra and its generics are the citizens of big cities. Now people think and talk about sex almost everywhere: at work, online, at the raves, etc.
For many people, the perfect man is the one who is ready for sex anywhere and at any time. Trying to meet these demands, men take pills in secret.
Despite the assertion that Viagra and its analogs are totally harmless, you should know that there is no there is no perfect drug without any side effects. Viagra, Cialis and Levitra are efficient in approximately 80% of cases. Levitra works at very low doses, which decreases the severity of side effects. However, it is contraindicated to the patients with cardiovascular diseases or the ones who have recently had a stroke.
Viagra, Cialis and Levitra act not only on the PDE-5-inhibitors and beta-blockers. For instance, Viagra and Levitra also include enzyme PDE-6, responsible for color perception, while Cialis prevents the activity of PDE-11 in the heart, the plug gland and the brain. However, the side effects they caused haven’t been known yet.
Another important factor is the interaction of Viagra with food and strong drinks. As far as we know, taken on an empty stomach, Viagra acts much faster than with eating. But even if you eat (in moderation), the effect comes, however, a bit slower. As regards the strong drinks, Cialis can’t be mixed with them- in contrast to its competitors. But, for example, Levitra can be taken in combination with alcohol. However, the advertisers don’t use it as leverage, as this assumption is questionable: drinking too much alcohol can lead to impotence.
According to the definition of impotence, it is a chronic inability to attain or sustain an erection for the performance of a sexual act. It is evident that Viagra and its generics only increase the blood flow to the penis and don’t have any psychotropic effects. In other words, Viagra is able to increase potency but can’t stimulate your sexual desire. However, according to the psychologists, most men with normal erection don’t have any problems with libido.
Therefore, the smart advertisers do not offer customers to use Viagra for the treatment of impotence, and call their products “playful drugs” (which is why Levitra is painted in bright orange color).
