Erectile dysfunction medication

There are three brands of FDA approved erectile dysfunction medication in the UK market. These are Viagra, Cialis and Levitra, the brand names for a group of substances known as phosphodiesterase type-5 (PDE5) inhibitors. These types of erectile dysfunction medications all act in a similar way and help men achieve their desired result of achieving and keeping an erection firm enough for satisfactory intercourse, with few side effects. Out of the three erectile dysfunction medications, Viagra is the most established and carries a 10 year safety record. Cialis lasts for the longest, up to 36 hours, and is also available as a daily tablet. The effects of Levitra, like Viagra last for several hours although it is said to work quicker.

How do erectile dysfunction medications work?

The three banded PDE5 inhibitors are sildenafil (Viagra), tadalafil (Cialis) and vardenafil (Levitra). They take effect within the body by relaxing the blood vessels in the penis to increase blood flow, which causes the penis to harden. An erection can only happen if there is sufficient blood flow to and from the penis. Oral erectile dysfunction medications do not have the ability to increase libido and can only work if the user is sexually stimulated in the first place.

How long do erectile dysfunction medications last for?
