General information on Viagra

Viagra is a drug used by men to treat impotence as well as erectile dysfunction. It is a brand manufactured by Pfizer using sildenafil citrate as an ingredient which works by increasing blood flow to the penis and relaxing its muscles. When men using Viagra are stimulated, they are able to achieve and sustain an erection in order to be able to perform sexually. Men with erectile dysfunction or impotence are normally not able to achieve an erection for sexual intercourse and therefore Viagra helps them achieve this erection.

An erection occurs when a man is sexually aroused and this happens when the arteries within the penis relax thereby widening to allow more blood to flow into the penis while those that carry blood from the penis become restricted thereby making less blood flow out making the penis to enlarge hence an erection. Viagra therefore helps men who cannot achieve an erection naturally achieve it after being sexually stimulated. It is a tablet that is taken orally at least half an hour before engaging in sexual activity and it has to be prescribed to you by a doctor. After taking Viagra, it may last between 3 and 4 hours and hence one can have sex within this timeline.
