There are many erectile dysfunction drugs available in the market for ED treatment. The leading products in the market are Viagra, Levitra, and Cialis. Viagra, Levitra and Cialis work to reduce the effects of an enzyme called PDE5. Reducing the activity of the PDE5 enzyme means more blood can flow to the penis and less leaves. The net result is an erection. There are also many generic versions of Viagra pills available in the market which costs less and are equally good for male erectile dysfunction problems.
Viagra: Viagra is a drug to treat erectile dysfunction (impotence) in men. It works by blocking an enzyme called phosphodiesterase-5, or PDE-5. This causes smooth muscles in the penis relax and elongate to let more blood to enter the penis. You get a bigger and harder erection by taking Viagra.
Levitra: Levitra seems to work for men with many different types of erectile dysfunction. It seems to work especially well for men whose erectile dysfunction is related to diabetes. In one clinical trial, it worked even better for diabetic men with severe erectile dysfunction than for those with milder problems.
Cialis: Cialis works faster than Viagra - in about 15 minutes instead of half an hour. It lasts a lot longer, helping men get erections for 24 hours vs. the four-hour window Viagra provides. |
