These are two drugs that belong to the same group of medications, the so-called PDE-5 inhibitors. What does PDE-5 inhibitor mean? It means that these drugs lower the level of or prevent the secretion of the enzyme which is called PDE-5. This enzyme is responsible for inability to have erection, and this is exactly the condition that the drugs treat – erectile or sexual dysfunction. So, when it comes to choosing the right medication, how do you decide?
First of all, the most important thing when it comes to comparing Cialis and Levitra is that they are both approved by FDA (Food and Drug Administration). This means that their ingredients and the dosages they come in are safe to use and that the side-effects that they may produce are not detrimental to your health. So, they have both been clinically tested and proven safe.
Also, both Cialis and Levitra function in the same way. As mentioned before, since they are called PDE-5 inhibitors, their generic substances (tadalfil and vardenafil respectively) inhibit this enzyme and thus make the muscles around your penis relax. This enables for the ample amount of blood to flow into your penis and thus enable erection. They are also responsible for enabling the hormones that help maintain erection stay in the penis longer which also makes your erection endure for the supposed amount of time.
Now, when it comes to the side-effects, these two do not differ. In fact, they cause basically the same side-effects which are usually headache, dizziness, stuffy nose, flushing; or some a bit more serious like temporary hearing or vision loss, irregular heart rate or some allergic reactions like itching, red skin or rash. However, the percentage of patients that have reported experiencing some of the side-effects is much lower in those who have used Cialis than in those who have used Levitra.
Further on, we come to the point that is probably of greatest interest for most of men, and that is effectiveness. Cialis is definitely the winner here. In fact, once you take a pill of Cialis, you will not be needing it for another 36 hours. That is how effective it is. Whereas with Levitra, you can only have one pill in the course of 24 hours, but its effectiveness will only last for four hours. Thus, in case you wish to repeat the act of pleasure again, you will have to wait until the next day.
In a nutshell, since Cialis and Levitra belong fall into the same category of drugs, it is natural that they are not very different from each other. In fact, there are more similarities than differences between them. However, the part that they differ in is the most important one for a lot of men. So, taking into consideration that they are both safe to use, that they have the same side-effects and that their prices are also approximately the same, it is obvious that Cialis is the one you should opt for because it can give you much longer hours of pleasure.
