All about Viagra tablets
Viagra is a medication used for the treatment of erectile dysfunction. Men who are unable to have normal erections are given a new lease of life ( so to speak) with the use of the drug. Viagra was released in 1998 by the pharmaceutical company Pfizer. Since its release Viagra has been used to improve the sex lives of many men and their partners. More than 50 million men have found relief of their conditions with the use of Viagra. Viagra is used so commonly that it is estimated for every second tick of the clock, 9 tablets are dispensed worldwide. Viagra is widely recognized as the most effective over the counter erectile dysfunction treatment and is constantly being studied.
Statistics show that when Viagra is taken correctly, it is found to work for 8 out of 10 men. It is important that proper instructions be adhered to. Overdosing on Viagra is not only a futile process, it is also extremely dangerous. The effectiveness of Viagra is not limited to the length of time the user has experienced impotency. Men who have suffered impotency for 10 years will recover just as quickly as men who have suffered the ailment for 10 months. The effectiveness of Viagra is also not affected by age. Young and old men can both use Viagra. However, because the ration of impotent men is found to increase with older men it is not uncommon to find that Viagra is used more by men over their 40s than it is below.
How Viagra works
The basic action of Viagra lies in its ability to increase the flow of blood in the penile areas. This is because an erection is caused by the increased flow of blood into the penis. Acting on actions similar to a balloon, sponge like tissues that can be found in the penis become engorged with blood and swell. It is this swelling that results in the effects of an erection. Viagra affects the actions of the body by inhibiting an enzyme which is known as PDE5. PDE5, when in natural occurrence, prevents the breakdown of the chemical messenger cGMP. With increased amounts of cGMP, it becomes so much easier for the arteries controlling the flow of blood into the penis to relax thereby allowing an improved flow rate. By allowing this, Viagra guarantees than an erection can easily be attained.
However the actions of Viagra are dependent on your sexual stance. Meaning, if you are not sexually stimulated, you will not be able to develop an erection. Taking the tablet merely guarantees that an erection can be achieved when sexual stimulation does occur. Viagra is not a hormone or an aphrodisiac. It is merely a drug that combats the effects of an erection.
The time required for the effects of Viagra to be noticed is found to be at least 30 minutes. Once taken, the drug is normally found to last for as long as 4 hours in the system. During this period normal sexual activity can be had for as long as is humanely managed.
