For anyone who is suffering from erectile dysfunction and is not sure what drug to use, the advice is: Don’t despair. Making the right choice is a problem we all face from time to time.
Presently, there are three prominent drugs available in the market for the treatment of ED, and all three are known phosphodiesterase type 5 (PDE-5) inhibitors and approved by the FDA. The most prominent of the three is Viagra, but popularity alone should not be a definitive reason for your wanting to buy Viagra tablets online, without giving a thought to the other two. The other two PDE-5 inhibitors, Levitra and Cialis, are just as effective and as safe.
To begin with, the three drugs are potent inhibitors of phosphodiesterase type 5 enzyme. What this means is that they are effective in increasing the levels of cyclic guanosine monophosphate (cGMP) by inhibiting the activity of PDE-5 in degrading cGMP. When a man is sexually aroused, he naturally experiences an increased level of cGMP which then relaxes the walls of the penile arteries, subsequently allowing for increased blood flow into the corpus cavernosum of the penis and erection.
However, when men who have ED are sexually aroused, they do not experience this increased level of cGMP because the PDE-5 degrades any available cGMP in their penises. When this happens, the relaxation of the arterial walls is not enabled and there will be little or no blood flow, resulting in the continued flaccid state of the penis.
What Viagra or Cialis or Levitra do is that it counteracts the effect of PDE-5 by blocking the enzyme. Blocking PDE 5 allows for the levels of cGMP to be increased when an impotent man is stimulated, and more blood will flow into the penis and erection becomes possible.
Why then should I prefer to buy Viagra online with next day delivery to Cialis or Levitra, since they are very similar in what they do in my body? One would want to ask.
Despite having the same mechanism of action, Viagra, Cialis and Levitra have some notable features which set them apart from one another.
Differences between Viagra, Cialis and Levitra.
Manufacturers.
The maker of Viagra tablets is Pfizer, Inc., and that of Levitra and Cialis are GlaxoSmithKline and Bayer and Eli Lilly and ICOS and respectively.

Two issues that have worried man from time immemorial are premature ejaculation and erectile dysfunction. It is not wrong to say that the key to holding down harmony in an individual’s marital life is a happy and active sexual life.
Indeed, an active and proper sexual life is an important ingredient that completes the physical demands of both the male and the female in a relationship.
A decision to buy Viagra online safely could be tantamount to getting a medication which plays important functions in the form of bringing succour to couples who under normal circumstances would have been troubled by the lack of active sexual life.
Known to be constituted of Sildenafil Citrate, Viagra, the popular drug manufactured by Pfizer, has brought a massive change into the lives of a great number of men who are suffering from erectile dysfunction. Working on certain chemical and scientific reactions, the drug is effective in the production and prolongation of erection in the penis, a requisite for sexual intercourse.
After one buys Viagra cheap, it is known that the drug begins to exert its effect within 30 minutes of being taken into the body.
Primarily, the focus of real Viagra tablets is to block the increased level of phosphodiesterase type 5 enzyme in the male reproductive organ. This is in addition to the fact that the smooth muscles are relaxed through a process known as ‘vasodilation’, which ultimately results in the increased flow of blood to the corpus cavernosum of the penis and subsequently erection.
Since the advent of real Viagra tablets, new avenues of male enhancement drugs have been opened, with the concomitant effect of creating a fiercely competitive market.
All over the world, companies have been carrying out robust and extensive studies and research to produce drugs which are cheaper and can effectively replace the already popular Viagra. Already, the spirited efforts of various organisations involved in the research have begun yielding fruits, with the formulation of herbal Viagra particularly catching the eye.
As previously mentioned, Erectile Dysfunction, as a major cause of unachievable sexual intercourse, could result in serious rifts in an otherwise model marital lives. Although Viagra and other phosphodiesterase type 5 (PDE 5) blockers like Levitra and Cialis were invented to correct this very common problem of Erectile Dysfunction, extensive studies and research have ushered in the formulation of herbal Viagra.
Going by the tendency of all humans to believe that any medicine that is either not natural or herbal would produce some adverse side effects, the need to formulate an herbal Viagra alternative has led to increased research on the course.
Talking about phosphodiesterase type 5 inhibitors – Viagra, Cialis, Levitra – both experts and laymen have commented that these drugs are capable of producing many side effects after use. Though some of the side effects mentioned are false, such claims that buying Viagra cheap deals could cause temporary impairment of vision, stomach upsets and flushing of face, are based on true facts and observations.
As a result of the need to get rid of and counter all such problems caused by allopathic Sildenafil citrate drugs, there has been a phenomenal increase in interest in herbal Viagra or herbal sexual stimulants. And this goes without saying that the herbal remedies discovered thus far have proved to be as effective as their allopathic counterparts, at least it seems.
Going by the encouraging result achieved thus far, one can be forgiven if one infers that herbal Viagra would play a significant role in the treatment of erectile dysfunction in the very near future.
Hence, the hope on herbal remedies as a viable option to bringing succor to many impotent males whose emotion and sexual lives have been adversely affect would be increased greatly.

For people who are hopeful of being a part of the Viagra revolution, but who are presently not because they can not buy Viagra online cheap, the likelihood of looking in the way of herbal Viagra tablets appears to be an attractive option. Another angle that favours the attraction of people to the herbal alternative is that people who want to buy Viagra online with no prescription can now get the natural version of the popular brand Viagra formulation, it seems anyway.
A formulation by Pfizer which has recorded unprecedented success since becoming available to men who are suffering from erectile dysfunction, real Viagra tablets are constituted mainly of sildenafil citrate.
Sildenafil citrate, a known inhibitor of phosphodiesterase type 5 enzyme (PDE5), which only works on a sexually aroused man, relaxes the smooth walls of the man’s blood vessels through a process known as vasodilation. The relaxation of the blood vessels is a key factor in allowing for the flow of blood into the corpus cavernosum of the penis and erection.
However, unlike the best Viagra tablets which contain sildenafil citrate, herbal Viagra tablets contain different active ingredients. Taken from the brand name Viagra, herbal Viagra is just a name given to any herbal product advertised as a treatment for erectile dysfunction.
Presently, there are many products that are advertised as herbal Viagra, with all of these drugs having active ingredients that are individually specific to them.
Among the products advertised as herbal Viagra is one product known as Duro.
Known to contain a fungus extract that is isolated from the larval remains of silkworms, Duro is believed to be beneficial to sportsmen and women alike through increased stamina.
It is on record that a great number of these herbal remedies are got from ancient tribes, such as Mapuche Viagra which is used by Mapuche people in Chile.
As mentioned earlier, herbal Viagra tablets, do not normally contain sildenafil citrate, which is contrary to the name suggestion. The use of the Viagra brand name as a generic term by many companies manufacturing drugs designed to treat erectile dysfunction, it can be theorised, is largely due to the unrivalled success of the drug in treating erectile dysfunction.
What are the side effects of herbal Viagra tablets?
A number of dangerous side effects have been associated with the use of herbal Viagra tablets. Prominent among the side effects are the ability of the drug to abnormally lower the blood pressure and restrict the flow of blood to vital organs in the body. Also, evidence suggests that some herbal preparations could be poisonous when taken in larger doses.
Where can one get herbal Viagra tablets?
The primary source of herbal Viagra tablets is the internet. According to a report, approximately 1 in 25 or 4% or of all messages sent via the email offered herbal Viagra tablets, other herbal remedies and other genuine pharmaceuticals for sale.
Are herbal Viagra tablets safe?
Todd B. Nippoldt, M.D, in answering the question of safety with the drug usage was categorical when he said that due to the fact that herbal Viagra tablets do not go through the rigorous standards of production as prescription and over-the-counter medications are made to do, endorsement of the drug as safe isn't possible
.
Brand Viagra tablets UK, unlike herbal Viagra tablets, are a prescription medication.
And many herbal products which claim to be natural versions of Viagra tablets online, are simply not the same as the prescription drug. Though, some contain vasodilators which improve blood flow to the penis by relaxing the walls of blood vessels, no herbal Viagra tablets are as specific for blood vessels to the penis as Viagra.
