Viagra is one of the most often applied preparations for impotence treatment in Australia and in the world. Under its commercial name, Viagra appeared in the European drugstores after the permission of tadalafil clinical application by the Europen Union. Tadalafil is a new means of fight against the impotence, created by the American companies Ely Lilly and Icos. This medicine is almost the same as Viagra, however the effect is reached quicker and remains in 2-3 times longer.

This new means of erectile dysfunction treatment named Viagra is a joint invention of the pharmaceutical company Eli Lilly and ICOS corporation. Viagra went on sale in Europe, Australia and New Zealand in 2003. «Viagra exit to the markets of Europe, Australia and New Zealand is an important event for Lilly ICOS», - declared Richard Pilnik, the president of Eli Lilly European department- «Viagra effect lasts the whole day and opens unique possibilities in the therapy of erectile dysfunction, allowing men to normalize their sexual life». «Viagra will be the best solution for over 31 million of men in Europe, suffering erectile disfunction» - tells Paul Clark, the executing director of ICOS. The ultimate Viagra advantage is that it restores man’s ability to erection for the period of 36 o'clock.

It is very important to underline that erection arises only in case of sexual excitement. It allows not to plan sexual relations and not to change the rhythm of life. It is possible to take a pill in the morning and to go to a date in the evening. Australian researches showed that Viagra action doesn't depend in any way on alcohol and the amount of food you take. That’s why for some men it is one more argument in favor of this medicine. However, it is necessary to note that alcohol negatively influences erection and can become the reason of erectile dysfunction.
