UK Viagra Patents

 

UK Viagra Patent

UK has a generic version of Viagra

I am from the UK and I am so happy that we have the opportunity to buy generic Viagra online. The best part is that the cost of Viagra dropped a bit when the UK patent for the drug expires.
This male erectile dysfunction drug that is manufactured by American firm Pfizer in Ireland, have to compete against generic competitors.
There are a lot of alternatives version of the drug that are made, some of them are even 85p per pill.

Great for everyone

This is good for many people. The price that was for Viagra was expensive and not many people can afford it. So because the patent has expired and because the competition that Pfizer will have, the Viagra price will probably fall. But if not, there will be the generic Viagra that will be the best choice in order to save money.
There won’t be any difference with the generic Viagra and the Viagra from the Pfizer. They will have the same main ingredient and will bring the same effect for those men who are looking for solution about the erectile dysfunction. It is great that it is legal.

Pfizer, maker of blockbuster erectile dysfunction drug Viagra, is expected to face new competitors in the UK when its patent on the drug’s process expires later this month.

This animation explains the malfunctioning chemical process which Viagra’s active ingredient treats.

During sexual arousal, the brain signals nerves fibers in arteries. These fibers release nitric oxide which triggers a chemical reaction. Cyclic guanosine monophosphate (cGMP) is then released causing the arteries’ walls to relax, increasing blood flow and producing an erection.”

Meanwhile, the enzyme phosphodiesterase-5, (PDE5) is counteracting the cGMP. As long arousal continues, the heightened blood flow and erection is maintained.

In cases of erectile disfunction, insufficient cGMP is produced and is overwhelmed by PDE5.

Viagra contains a PDE inhibitor which bonds with the enzyme and stops it from counteracting the cGMP. This allows enough of the chemical to accumulate and relax the artery walls, producing an erection.,
