Viagra Professional is a new generation extra-strength medicine for the treatment of erectile dysfunction, based on a well known sildenafil citrate, the active ingredient in regular Viagra and other similar ED medicines. It is one of the most refined and individualized forms of sildenafil citrate 100 mg.
Viagra Professional helps both get and maintain erection by affecting the response to sexual stimulation. Sildenafil citrate acts by enhancing smooth muscle relaxation. This smooth muscle relaxation allows increased blood flow into certain areas of the penis, leading to an erection.
After a man takes Viagra Professional, he must be sexually stimulated for it to work. This can include kissing or touching. Once a man takes Viagra and has sex, his erection will go away after intercourse, just like it would normally. Viagra Professional works in as quickly as 30 minutes and lasts for about four hours.
