The pharmaceutical company Pfizer at first developed the medication in 1989 as cure for high blood circulation pressure and angina.Unfortunately, early medical trials weren't positive. To really have the right impact the drug needed to be used three times each day and it offered a few of the patients muscle pains. It had been also discovered to connect to nitrates (the typical treatment for angina), which led to an unsafe drop in patients' blood circulation pressure.Fortunately, some patients had reported the delayed side-effect of erections. Because of this, the concentration on Viagra transformed to its intimate applications.After clinical testing, it was approved for use in Australia in 1998, having been approved in America nine months previously.
