Viagra is a drug that everybody has heard about, we’ve all seen the commercials. But many people actually know that his pill is not just used for erectile dysfunction. Viagra or Sildenafil can be used as well to treat pulmonary arterial hypertension. Of course there would be different guidelines between the uses of the drug for each particular problem. Viagra has been on the market for consumer use since 1998, it’s main competitors are Cialis and Levitra which are the other two most popular erectile dysfunction medications available on the market today. Generic Viagra is not recommended for use by males who already suffer from heart problems as it may only worsen the condition and have severe side effects.
The medication was originally intended to be used by hypertension sufferers and patients with bad hearts. Revatio is another name that Viagra is commonly sold under, the names have no type of effect on the medication. Viagra was the first erectile dysfunction medication that was patented and sold for use in the United States. It is all about the chemical compound and what type of drug this particular medication is made up of. Viagra is also known as ‘the magic blue pill’ by men that have tried it and that have experienced great results from the usage of it. The pill is also diamond shaped and comes in 25, 50 or 100 milligrams dosages. The company name of Pfizer is also engraved on the small blue pill. Viagra used to be only available by a prescription from your doctor, but now you can order it off of television and even online from reputable dealers for a lot less than the pharmacist will charge. The success of Viagra has recently declined over the years from well known competitors Cialis and Levitra coming on to the market as well, side effects such as severe vision loss have also been claimed to be a contributor factor in the decline of sales. In England, Viagra can be purchased over the counter by men the ages of 35 and 65 after speaking with a pharmacist. Just like any other type of product the patent for Viagra will expire, it will expire in the United States under Pfizer in the year 2012.
