Understanding Erectile Dysfunction (ED)

It’s a common belief that Cialis leads to a “harder” erection than Viagra.

• Some men wrongly believe ED tablets work instantly – they require sexual stimulation.
• ED tablets are not aphrodisiacs; they only help achieve and maintain erections.
• Taking more than the prescribed dose does not improve effectiveness and increases risks.
• ED tablets cannot cure underlying causes like low testosterone or psychological issues.

However, from a pharmacological standpoint, both work similarly by facilitating erection in response to sexual stimulation.

Your questions about ED pills, answered

Erectile dysfunction occurs because not enough blood gets pumped into the penis or the blood that does get pumped in leaves too quickly — often when it matters most. Viagra is one of the most common PDE5 inhibitors available. Sold as a diamond-shaped blue pill, it has been bought by over 62 million men worldwide. But while most men have heard of Viagra it isn’t the only type of erectile dysfunction medication that exists. For men whose bodies do not respond as well to the active ingredient sildenafil there are prescription-only drugs like Cialis (active ingredient tadalafil) or Levitra (active ingredient vardenafil).

How avanafil works and why onset can be faster

Some men like tadalafil because the effects last longer than other erectile dysfunction pills (often up to 36 hours). By this we mean you should still be able to get an erection the next time you have sex. Being erect for 36 hours straight is dangerous — even an erection that lasts over four hours requires urgent medical attention. Tadalafil helps boost blood flow to the penis, which in turn helps you to get hard. Sexual stimulation causes a chemical called CGMP to be released into the penis, which carries blood to the area and causes an erection.

Restricted Blood Flow Blocks Erections

A while later PDE5 is released, which destroys the CGMP and causes blood vessels to return to their normal size. Tadalafil stops PDE5 from doing its job properly, which helps your erection last longer. Remember though, it will only work if you’re already sexually stimulated. You should take it two hours before you have sex. Vardenafil is the active ingredient in Levitra, a prescription-only ED medication that lasts for up to 4 hours. The key difference lies in their duration of action. Cialis, with a longer half-life, offers extended responsiveness, which some might interpret as vardenafil canada a more “available” erection.
