In 1998, after numerous clinical and laboratory studies the first medical drug for the treatment of erectile dysfunction was developed and it was called Viagra.
Viagra has been produced on the basis of the known drug Sildenafil which provides a strong action at the insufficient blood flow into the penis and helps to regulate the male erection. Sildenafil citrate has been developed and produced by the Pfizer Company which registered a trade name Viagra, and now this drug is for sale under this name.
A patent for the production of Viagra ends in 2012 but today there are a lot of analogs of this drug that are released under other names by small pharmaceutical companies. These cheap analogs are called Generics and sold successfully in comparison with the expensive brand Viagra.
Generics Viagra are considered the best alternative in the treatment of erectile dysfunction because they are produced on the basis of Sildenafil and the pharmacological action of all drugs is the same. Thanks to the different Generics Viagra the manufacturers have to think up new ways of the satisfaction of the male needs. That is why every new drug has its individual properties right up to the medical form.
The appearance of the medical product Viagra has started the medicated treatment of erectile dysfunction, and today millions of men are grateful for the efficiency of this drug and safety in erectile dysfunction treatment.
