Viagra, a sildenafil citrate tablet, is the world's most popular oral drug for the treatment of erectile dysfunction. Erectile dysfunction, which is also known as impotence, has been affecting men of all ages. That is why this small blue tablet became revolutionary ever since it was invented by British scientists in 1998. Now, almost every adult around the world knows the name and function of this pill. In the years since 1998, the Viagra pill has allowed millions of men, who are sexually stimulated, reach and prolong their erection, improving their sex-lives and self-value significantly. Because of this pill, men of all ages have discovered their long - lost sexual youth all over again.
Viagra is highly effective. It works by slowing down the phosphodiesterase enzyme. The phosphodiesterase enzyme is responsible for reversing the erection. By slowing it down, the sildenafil tablet allows more of the chemicals which are responsible for penile erection remain in the system. This keeps the muscles in the penis from constricting, which, in turn, allows blood to remain in the penis for longer periods of time. Thus erection is prolonged. However, Viagra cannot achieve its purpose without prior stimulation of the penis. This is because the pill has no effect on the chemicals which are responsible for the erection of the penis. Such chemicals can only be released when the man is properly aroused. But if stimulation has already occurred, the Viagra pill is successful in prolonging the erection.
The Viagra pill is blue and in the shape of a diamond. The word "Pfizer" is engraved on one of its sides and the dosage is engraved on the other side. The drug comes in doses of 25mg, 50mg and 100mg. It is recommended that men under the age of 65 take a 50mg Viagra pill once a day. The Viagra tablet should be swallowed whole and washed down with water, preferably half an hour to four hours before the anticipated intercourse. In case it is not effective, the dose may be increased to 100mg or lowered to 25mg, if the effect is too strong. For men older than 65, the proper dosage of Viagra is 25mg, also taken half an hour to four hours before intercourse. But that is a general dosage, and may not fit every individual. To achieve the best results, a proper dosage must be chosen according to the man's age, the severity of his erectile dysfunction, and on the other drugs the man is already taking. Sometimes, the other drugs in the man's system may interact with the Viagra drug. In this case, the Viagra dosage will need to be adjusted. But one rule that is true for all men is that the pill should never be taken more than once a day.
How long the sildenafil citrate tablet takes to work varies from person to person, but usually it works relatively fast. For most men, it takes effect in thirty minutes, but sometimes it can take as little as fourteen minutes to work. All of this depends on the individual and the situation. If taken on an empty stomach, the pill works faster, but if it is taken after a high-fat meal, the Viagra pill may take longer than an hour to take effect. Drinking alcohol can also temporarily interfere with the erection, so it is advised that men should not drink large amounts of alcohol prior to taking the Viagra pill. How long the tablet stays active also varies from person to person. For some men, the Viagra pill continues to work for four hours or even longer, but the average is approximately two hours. After the intercourse, the erection disappears, but the pill continues to stay effective for up to 12 hours.
The developers of the drug have done many clinical trials on almost 4000 men. These trials have demonstrated that compared to a placebo pill, the Viagra tablet is highly effective in the treatment of erectile dysfunction. It has been proven that the pill is safe, but like any other medication, Viagra can become the cause of some side effects. Most side effects are mild to moderate, relatively brief in their length, and usually do not cause any distress. The most common are headaches and facial flushing. That is why it is important to take a correct dose of Viagra, and consult your doctor if something does not go according to plan. Also, it should be known that the pill was developed for men. It has not been licensed for the use of women and clinical trials have not been done on the subject. Thus, it should never be used by women.
A long-term study of the pill has demonstrated that 88 percent of the men who took the Viagra pill said their erections improved significantly. That's why Viagra remains the world's most popular and most effective medication for erectile dysfunction.
