| The enzyme responsible for stopping an erection in men is the main cause behind erectile dysfunction (ED). Men who have complications regarding this issue tend to buy PDE-5 inhibitor which pretty much is the best cure for ED, but which brand to go for? Now we know the popular one which is Viagra but there are also newer and better inhibitors in the market that are slowly stealing the competition.

So far there hasn’t been an official report or comparison between the available drugs used for the treatment of ED. But three of them have been approved by the FDA which gives them a license to be official PDE-5 inhibitors. Viagra is has been in the market since 1998 which gave it a head start against its competitors. It was invented by the US based Pharmaceutical Company Pfizer. When it was being sold in the initial stages, it brought a whole new meaning to men affected by ED and sold like dope. But after a while in 2003, another pharmaceutical ICOS company claimed it had engineered a PDE-5 inhibitor which gave better success rate than Viagra or any other PDE-5 inhibitors. This was quite the barrier breaker for Viagra but the new drug Tadalafi marketed by the name of Cialis came quite the ideal erection stimulator.
