What is Viagra for?

viagraMale strength is not only measured by well-developed muscles or maximal weight they are able to lift.  Much oftener a “real man” implies a man with good potency who is able to perform in the sack successfully, i.e. have a normal erection lasting as long as needed.
It is good if you can count yourself among the “real men”, but due to some factors many men are exposed to, you can easily lose this status. It is crucial to discern the symptoms of the impending “disaster” in time and start taking care of your sexual health. Such symptoms include: reduction of sexual appetite, temporary absence of erection or weak erection. Timely treatment may help to avoid more complicated conditions.
If you experience any of the above mentioned symptoms  but at the same time have normal test results and have no urogenital diseases, it means it is high time for you to change something in your life style if you want to enjoy sex long. Viagra is a peroral medication elaborated by Pfizer. The medicine shows high effectiveness in most patients suffering from erectile dysfunction.    The active ingredient in Viagra is Sildenafil citrate.
Viagra comes in 25, 50 and 100 mg tablets.
The action of Viagra consists in intensifying blood flow to the cavernous bodies of the penis and at the same time the active ingredient of the medicine inhibits outflow of blood from the penis. This provides a hard and long-lasting erection. The great advantage of the medicine is the naturalness of its mechanism. The medicine only works in response to sexual stimulation, and after sexual intercourse the penis comes into its relaxed condition as before sex.
