Viagra Original is produced by the American company Champix and anti-anxiety medication such as Xanax. Pfizer invests a large amount of money annually in drug research and development.. Another brand of sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. Pfizer's small blue tablets are considered to be the best-known stimulator of male potency. It has been 15 years since this drug is used in France to treat erectile dysfunction (impotence). The drug made its appearance on the market in 1992 and became the first stimulator of male potency. Helpless men have trusted Viagra and this continues to the present day.
Viagra was one of the first treatments to be approved for the treatment of erectile dysfunction and has been used by men across the world for over a decade with excellent results. Pfizer was the original manufacturer for Viagra and developed a patent on the product in 1996. Originally Viagra was used for the treatment of heart disease, but during clinical trials it was noticed that it also helped treat erectile dysfunction. In 1998, Pfizer received FDA approval to license the product for the treatment of erectile dysfunction.
In 2013, the Pfizer patent on Viagra ended in the EU, allowing generic manufacturers to start producing their own version. The generic version of the drug is known as Sildenafil which is the active ingredient in Viagra. The name Viagra is still a brand name which only Pfizer can use. So effectively in the market the drug can be bought as either the branded Pfizer product Viagra, or the generic drug Sildenafil.
Viagra is taken in pill form as and when required, typically 30 minutes or an hour before sexual activity commences, although you can take it up to four hours in advance. It should not be taken more than once per day. It should be noted that the pill alone will not induce an erection but must be accompanied by normal sexual stimulation. You should always follow the instructions regarding dosage and use of the drug. The blister packs contain four, eight or 12 tablets each.
If you are not affected by any form of Erectile Dysfunction then it is inadvisable to take Viagra. It will not increase the size of your penis, as is popularly assumed, nor will it increase your libido. It is not an aphrodisiac and does not induce spontaneous erections. Viagra only works in conjunction with normal sexual arousal, and as such is not a miracle drug but rather an aid to normal sexual activity for men who find it difficult to achieve and maintain an erection.
As is the case with many medications this sexual stimulant can cause side effects in the form of mild dizziness, redness of the facial skin, rashes and itching. These symptoms are not important, they are short-lived and usually do not cause significant problems to the patient. Quite rare, there are digestive disorders and nasal congestion that seem insignificant. But still, Viagra is the most reliable ED med in the world.
