Buy Viagra Pfizer Online in the UK
Viagra Pfizer tablets are taken for the treatment of men with erectile dysfunction; which is the inability to achieve or maintain an erection sufficient for sexual performance. In order for Viagra to be fully effective, sexual stimulation is required. Once the tablet is taken, it should take between 30 - 60 minutes to start working. The effects of the medication could then last between 4 - 5 hours.
Pfizer submitted a patent application in 1994 that covered the use of sildenafil to treat erectile dysfunction. This has since been sold under the name Viagra. This patent was released in 2002 and ran out of protection in 2019. Since the patient ran out, men have been able to attain Sildenafil tablets, they work exactly the same as viagra but are much cheaper. To see more information about our Sildenafil tablets click here.
