Interesting thing but we have always progressing inventions (if it possible to name this so) or breakthrough among the cadiovascular medications. One of basic and expected "side effect" of them is treating many other deseases such as Erectile Dysfunction (knows also as ED).
A couple years ago there was approved by FDA one brand new ED drug - Staxyn. And for about one year there are so many having tried mankind agreed with that approval - Staxyn works! And works for all of them with softer side effects than the good-known sildenafil/tadalafil tablets (I mean Viagra® by Pfizer and Cialis® by Eli Lilly).
