Generic Viagra — is the first and the most well-known remedy for male erection. Its active ingredient is called Sildenafil. It provides enhanced blood flow to the male genital area. The cavernous body is relaxed, then is filled with blood abundantly, whereby an erection appears, sufficient to perform an act of intimacy. Sildenafil has no effect on the brain. An erection is achieved only if there is a natural sexual arousal.
Viagra Professional is an extra-strength version of the first sildenafil citrate drug to treat erectile dysfunction.It is chewable and this Indian drug has all the advantages of the regular pill. Absorbed directly into the bloodstream, it acts faster, and guarantees prolonged effect. Another purported advantage of Viagra Professional not found in the original is the stimulation needed to achieve an erection. The makers of Viagra Professional attest that less stimulation will be needed prior to intercourse than before, as the nerves of the penis will have a greater sensitivity.
