How was the compound Sildenafil Citrate (Viagra) found and what was it extracted from?
Are Tadalafil Citrate (Cialis) and Vardenafil HCL (Levitra) extracted from the same plant source as Viagra is?
It wasn’t necessarily extracted directly from a plant source. Scientists at pharmaceutical companies systematically study molecules by the millions. Some of which were taken from plant sources and some where not. Most of them are modifications from previously studied molecules. They might extract a substance from a plant, analyze its molecular composition, then find one molecule that shows promise and warrants further study. Then they might find that the molecule isn’t desirable for some reason, so they might slightly alter the molecule, then test the new molecule that was formed, and so on. They literally study and discard millions of molecules before finding the one that demonstrates a useful medical application. With computers this process is much faster than it used to be.
In the case of Viagra, sildenafil citrate was originally being developed to treat ischemic heart disease. During human studies, they found that sildenfil didn’t demonstrate the promise they had hoped for, but in gathering feedback from the patients on side effects, they stumbled across the “side effect” of a hard erection in patients that hadn’t had a “good erection” in years. They decided to study it further and found it was very effective for this purpose. They realized that erections are regulated by an enzyme in the body called phosphodiesterase. Variations of this enzyme are found throughout the body effecting various things, and are numbered for classification purposes. The phosphodiesterase in the penis is called “PDE5″. Other enzymes like PDE11 are found in skeletal muscles. In a nutshell, PDE5 prevents an erection by gobbling up nitric oxide. Nitric oxide is released during arousal to cause the erection, but impotent men have too high a threshold of PDE5 to allow it to happen. Viagra, Cialis, and Levitra all work by temporarily inhibiting PDE5, thus nitric oxide is released during arousal and is allowed to cause the erection. The differences between the drugs is due to the levels at which other PDE’s are inhibited. Viagra also inhibits PDE3 which is found in eyes, relating to color vision, which is why you can sometimes have a temporary bluish tint to your vision. And Cialis inhibits PDE11, which causes an increased incidence of sore muscles. The drugs also differ with regard to their onset of action, and half life.
is it easy to get……what did you have to do to get it? or is it just as easy as going to your doc and saying to him you want it and he gives you some?
i know what it is…..i want to know if its easy to get from a doc
.viagra is a prescription drug, so you must get a prescription from your doc. if you have ed the doc will give you a free ed sample pack of viagra cialis and levitra to see which one works best for you. if someone is diabetic and has ed, he can get free viagra if his doctor prescribes it to him.
You can also try to order viagra online, the only problem with buying viagra online is that there are so many sh..ty places all over the net that you can easily get lost and get ripped in the end.
you must be very careful if you choose to order meds over the net. a good source for ed meds like viagra cialis levitra is http://www.viagrafans.com . it is not an online pharmacy but an online community of viagra cialis and levitra users, the site also has got price comparison of cheapest and trusted online pharmacies.
I know Viagra let’s more blood flow to the penis and a pump also let’s more blood into the veins what will happen if I use both,my girlfreind has a large vagina from prior use and I want to satisfy her.
There is NO SUCH THING as a large vagina from prior use.
Men are so ill-informed, sometimes. A vagina does NOT “stretch out,” like that, there is no such thing as being “loose.” Even if she had sex three times a day with well-hung guys for years of her life, she wouldn’t be “loose,” and nothing would change. The ONLY thing that stretches it out is childbirth, and after a month that is almost imperceptible.
Don’t do that. Even a small guy can satisfy a girl if he knows what he’s doing… my guy is only 3 inches and he still makes me scream.
people in my address book are receiving viagra and cialis adds using my email address. how do I stop it?
this is tricky people could get the wrong idea, you could block the original ad as reporting as spam or unsubscribe to the host that is sending them, or i would send an email to everyone stating ur email has been hacked apologising for any offence incurred as you were not meaning to offend

No way something called cheapviagrabuy.com can be a good online pharmacy:)))
the net is full of online pharmacies, some are cheap, some are overpriced, some will send you your meds, some only an empty envelope or no envelope at all. you should do some research and keep eyes open when ordering viagra cialis or levitra online. http://www.viagrafans.com is a good source.
it is not an online pharmacy, but an online community of viagra cialis and levitra users. the site also has got price comparison of cheapest trusted online pharmacies for all 3 – viagra cialis levitra.
People started getting mail about Viagra from a Canada Pharmacy from my contacts. I did not send them. They get them often and how do I get rid of it. Is it a virus or hacking?
Sounds like you got compromised. First change your password. Account help.http://help.yahoo.com/l/us/yahoo/acct/in… for just about anything to do with your account. Then run anti Virus and Anti Spyware. Should be fine then.
It calls my attention that Viagra is sold without prescription online. What’s the catch?
its legal in Mexico and many European countries. I buy generic cialis online from Europe from the site at World-Rx.Net and they deliver it to my mailbox without any problems.
