Define Viagra sildenafil
Viagra sildenafil belongs to a class of medicines called Phosphodiesterase Type 5 (PDE5) inhibitors. Sildenafil - the active ingredient in Viagra helps men with ED get and maintain erections in response to sexual stimulation. When a man is sexually stimulated Viagra sildenafil helps the arteries in the penis relax and widen and thereby allow more blood to flow into the erectile tissues. This mechanism makes the arteries expand and harden. Simultaneously, the veins that carry blood away from the penis become compressed, restricting the blood flow out of the penis. The action of Viagra sildenafil in the body therefore makes more blood flow into the penis and less blood to flow out of the penis. The engorgement of penis with blood makes the penis larger and harder, causing an erection. The action of Viagra sildenafil causes a prolonged erection sufficient for sexual intercourse. After the sexual activity is over, the erection goes away and the penis returns to its normal flaccid state.
Viagra sildenafil is to be taken as needed after seeking prescription from a doctor. Once taken Viagra becomes effective within 60 minutes and its effect in the body lasts for about 4 hours.
