Viagra Patent Expired in UK.

by admin on February 12, 2014

Ever since the patent on Viagra expired in the UK in June 2013, the price of generic Viagra has been falling back to realistic levels. However, most high street on-line pharmacies in the UK are still overcharging for generic erectile dysfunction medications, i.e. not just for branded Viagra but cheap generic Viagra a.k.a. Sildenafil.

The generic Viagra price comparison table will show you in a glance where the best deals are and what online pharmacies to avoid.

Viagra® is the branded name for a erectile dysfunction medication composed of Sildenafil Citrate. It was first developed as a drug to treat heart disease (Angina) in Kent, England. During clinical trials in Swansea, Wales it was discovered that Sildenafil also had the effect of producing extended erections among men. The Pharmaceutical giant Pfizer branded it as an erectile dysfunction treatment and called it Viagra.

Although marketed and bought primarily as an erectile dysfunction treatment, Viagra, or more specifically, Sildenafil, the primary ingredient of Viagra, has other uses such as the treatment of pulmonary hypertension. It has also used in ‘altitude sickness’ among mountain climbers. It has be shown to be beneficial in treating jet lag (at least in hamsters) and will also allow cut flowers to remain erect longer in vases (according to reports – I wouldn’t waste Viagra on flowers myself :)).

There are also suggestions that Viagra‘s effect on the circulatory system could help improve athletic performance – although this hasn’t been studied sufficient to be conclusive. generic Viagra erectile dysfunction medication

Viagra has grown from being a erectile dysfunction treatment to becoming a widely used recreational drug for enhance sexual pleasure and performance among men.

And not only men. Sildenafil is now being marketed for women as ‘Viagra for Women‘. Given that it assists an increased blood flow to the genital area it is thought to enhance sexual pleasure and responsiveness among women.

A common myth concerning Viagra is that it causes the penis to become erect which is strictly speaking not true.

What it does do is suppress a naturally occurring chemical call PE-5 that itself blocks the relaxation of blood vessels and hence makes gaining and sustaining an erection more difficult – particularly as we get older. You still have to be sexually stimulated to achieve and erection. Viagra taken without sexual stimulation will not cause an erection in most cases.

Generic Viagra and its derivatives are sold in different dosages – 25mg, 50mg, 100mg are the most popular but it is possible to purchase up to 200mg of Sidenafil per pill.

A 25mg dosage of Sidenafil taken 30 minutes to an hour before engaging in sexual activity is usually considered adequate for most people.
