Drugs that can treat ED are Sildenafil, Tadalafil and Vardenafil
Erectile dysfunction is defined as the inability to maintain sufficient erection to complete sexual intercourse. And as per that definition itself, you must be able to imagine how frustrating it can be for men to have such. Once before a few decades back, men had no choice when they had this but to just succumb to the problem as it really deprived them of sexual pleasures and there was no treatment available for this.
But luckily in our era now, we have the help of major drug like Sildenafil or Viagra to help us treat erectile dysfunction. It was only in the late 90s, in fact exactly 1998 when Pfizer released Viagra but that really helped start a revolution that saw millions of men now coming out and buying these medications as this was the first time in many many years that an effective treatment for one of their conditions have come out and erectile dysfunction really found an enemy in these drugs.
After Viagra came Tadalafil or Cialis which was as I think just a variant of sildenafil, but there also was Vardenafil or Levitra which is another major drug for ED to come out in these times. These three have played a major role for men in their fight against erectile dysfunction and they are all very potent drugs to help impotent men who suffer from the condition achieve their desired erection to finally complete sexual intercourse up to the ejaculation phase.
