Revatio: Uses, Dosage & Side Effects
Revatio is one of the generics of Viagra, with fast action and good tolerability. Does it really suit most men and rarely cause side effects? What are the features of this medicine? Can you use it to achieve the best result? About this, you will learn from the article below.
Erectile dysfunction (ED), at the end of the 20th century, became a completely curable disease. Thanks to PDE5 (phosphodiesterase 5) inhibitors, men can get rid of impotence very quickly and simply. One of the most popular drugs for ED treatment is Viagra. This medicine speaks for itself, and it even has become a household name.
At the moment, this medication is not available to everyone – until 2020 it will be sold only by prescription and has a rather high price. However, this is not a problem, because there is Revatio – a quality generic, which is composed of the same active ingredient – sildenafil. Due to this, these drugs work like Viagra, are same effective, but their cost is much lower. You can also buy them over-the-counter, which is very convenient. Let’s find out more about this drug.
Brief Information About Revatio
Revatio is a drug that is identical to Viagra 100 mg in composition and action. The main difference between them is that this medicine is produced in India according to the classic recipe and does not have a brand markup. Viagra is a brand name, and this unfairly raises the price of the drug. For this reason, Revatio is much cheaper. There is no patent on this drug, so you can buy it freely and OTC. However, buying a drug without a prescription requires from the buyer, the self-analysis of his health state is to avoid the possible risks.
Revatio action is identical to other drugs based on sildenafil citrate. If you have previously taken the original Viagra, and it suited you, then you can safely use Revatio instead of it.
The drug is effective if psychological or physiological reasons cause impotence. It, most likely, will not help if a man has a strong hormonal failure or serious injuries of the genitals.
Mechanism of Action
Sildenafil in Revatio composition reacts to nitric oxide, which appears in the body during sexual arousal. At this point, many mechanisms that lead to erection are triggered, and sildenafil enhances them, as well as increases arousal. This substance inhibits PDE5 enzymes, and due to that an erection remains strong for entire sexual intercourse until orgasm, and will not disappear at the most inappropriate moment, as is often happens in men with ED. Revatio improves blood circulation and relaxes smooth muscles, contributing to the complete filling of the spongy and cavernous bodies of the penis with blood.
The drug begins to act only during sexual arousal, so do not worry that an erection may occur spontaneously at the wrong time; this will happen only when it is necessary.
Does Revatio Work Like Viagra and Cialis?
As already mentioned, the principle of Revatio work is the same to Viagra and other PDE5 inhibitors used for the impotence treatment. Viagra, Cialis, and Stendra – all of them have a similar action. The only thing that distinguishes Revatio from Cialis and other tadalafil-based drugs is the duration of action. Revatio works from four to six hours, and Cialis – up to 36 hours. In all other respects, these medicines are similar. Although drugs with different active substances work according to the same principle, they can be tolerated differently – it all depends on the individual reaction of the organism.
