The effect, use and online purchase of Cialis
Cialis is after Viagra the best-known and most used medicine against erection problems. Cialis is a brand name, the active substance in Cialis is tadalafil. Since the Cialis patent expired and generic variants have become available, the price has fallen significantly, further increasing popularity. This article discusses Drs. Fisher including the effect, benefits and possible side effects of the drug Cialis.
Cialis is a PDE- 5 inhibitor, this is how it works.
The active substance in Cialis is tadalafil, and belongs to the group of PDE-5 inhibitors. PDE-5 inhibitors work by blocking a specific enzyme reaction in the body, causing the blood vessels in the penis to relax. The result is improved blood flow that makes it possible to get and maintain a harder erection when sexually aroused.
Cialis works for up to 36 hours
Where Cialis differs from Viagra is the duration of action. Where other erection drugs often work for four to six hours, Cialis can have an effect for up to 36 hours. As a result, it is also known as the “weekend pill”, because it offers more flexibility compared to other medications. It is good to know that erection drugs such as Cialis and Viagra only work with sexual stimulation. So it is certainly not the case that taking Cialis leads to a 36-hour erection. This is a good thing, because an erection that lasts longer than 3 to 4 hours is dangerous. This can lead to damage to erectile tissue. So contact a doctor immediately if you have an erection for more than 3 to 4 hours in a row.
What are the benefits of Cialis?
Cialis is popular because it is not only effective but also offers flexibility in use. Because the duration of action lasts up to 36 hours, a tablet does not have to be taken exactly before sexual activity. In addition, the effectiveness of Cialis has been proven in numerous clinical studies, such as in this University of North Carolina study. This makes Cialis or tadalafil a trusted choice for men worldwide. In addition, the competitive price for the generic tadalafil has further increased the popularity. These generic variants became available after the expiration of the Cialis brand name patent.
Cialis may have the following side effects
Overall, Cialis can be used without problems and safely. There are, however, a few possible side effects.
