Erectile dysfunction medications
A popular erectile dysfunction medication is Cialis, taking Cialis should help you maintain an erection for sexual intercourse when stimulated. Cialis is known as the weekend ED drug because once you take it the effects last for around 36 hours. That doesn’t mean you sustain an erection for thirty six hours but the ability to have an erection through stimulation.
So how does Cialis work? Well the active ingredient in Cialis is tadalafil, tadalafil is a phosphodiesterase type 5 inhibitor and it prevents the action of a chemical in the body called phosphodiesterase type 5. Phosphodiesterase type 5 is what breaks down Cyclic GMP, Cyclic GMP causes the blood vessels in the penis to widen by relaxing a thin layer of muscle found in the blood vessel walls. So if Phosphodiesterase type 5 breaks down the Cyclic GMP you won’t get an erection, which is where Cialis comes in!
There are side effects when taking Cialis like any other erectile dysfunction medication which you need to be aware of before you take it.
