Sildenafil reviews: effects, dosage, side effects
1. Sildenafil reviews: history
Sildenafil, also known assildenaifl citrate, sildenafil citrate was created in 1989 by British scientists Albert Wood and Peter Dunn as a possible treatment for hypertension and angina; conditions associated with coronary heart disease. In 1991 Dr. Nicholas Terrett, now often referred to as the father of Viagra, was named in the British patent for the drug as a heart medication. And though Pfizer’s early trials of the drug in the 1990s did not prove its efficacy as a heart medication, patients who took part in the clinical trials reported increased erections after taking sildenafil. Separate studies provided more information on the biochemical process that causes erections, which helped scientists understand how sildenafil could enhance the effects of sexual stimulation and open up blood vessels in the penis. Sildenafil was then studied in men with erectile dysfunction, and in 1998 it was approved by the FDA specifically for treatment of ED.

The brand name of Sildenafil citrate is Viagra. Sildenafil citrate is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Sildenafil (Revatio) is used to improve the ability to exercise in adults with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Children should not usually take sildenafil, but in some cases, a doctor may decide that sildenafil (Revatio) is the best medication to treat a child's condition. Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily.
If you are taking sildenafil to treat erectile dysfunction, you should know that it does not cure erectile dysfunction or increase sexual desire. Sildenafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).
3. Sildenafil reviews: how long dose sidenafil last?
The effects of sildenafil will vary from person to person. As a general rule, Viagra is thought to start working in most people from around 30 minutes after taking the drug.
It is important to understand that taking Viagra tablets alone will not cause an erection. Sildenafil must be taken in combination with some form of sexual stimulation (visual, tactile or otherwise) in order for an erection to occur.
The length of time sildenafil lasts for will also vary from person to person, but it has been known to work for up to 5 hours at a time, when used alongside sexual stimulation. Most men will find, however, that the effects of the pill will start to wear off 2-3 hours after first taking it.
There are certain factors that will contribute to how long Viagra will last for in your individual situation, and you should always discuss your full medical history and details of any medicines you are currently taking before starting a course of treatment with sildenafil.

Sildenafil dosagesusually begin at 50mg taken when needed =1 hour before sexual activity no more than once daily.

More than 3000 patients with erectile dysfunction of organic (e.g. diabetes or spinal cord injury), psychogenic or mixed origin received sildenafil 5 to 100mg or placebo in fixed- or titrated-dose trials. Sildenafil was associated with dose-related improvements in the frequency, hardness and duration of erections and in patients' abilities to achieve and maintain erections adequate for successful sexual intercourse. In titrated-dose trials, the most commonly effective doses were 50 or 100mg, although lower doses were effective in some patients. Sildenafil was significantly more effective than placebo in erectile dysfunction of all tested causes. The efficacy of sildenafil was not affected by patient age (> or < or =65 years) or by antihypertensive or antidepressant medications. The drug was effective in patients with severe erectile dysfunction. Efficacy was maintained in long term (1-year) studies. Sildenafil also appears to improve the quality of life of both patients and their sexual partners
