What is the difference between Cialis and Viagra?

Viagra (sildenafil) and Cialis (tadalafil) can take effect in as little as 1 hour, but for some patients these drugs can work even faster. Sildenafil will have an effect reliably for 6-8 hours, but tadalafil will have an effect for up to 36 hours. Considering the benefits and risks of Cialis versus Viagra requires some basic knowledge of both. A brief comparison of Viagra vs. Cialis can be made by examining how they can be used ("as needed" for both or daily for Cialis), the time it takes for them to take effect, how long they continue to have an effect, and the side effects these can cause.

Side effects are rarely the only factor men consider when taking drugs for erectile dysfunction . It is the interplay of a man's social circumstances (and partner), his need for a quick effect of medication versus a long duration of effect, the individual reaction to the drug in terms of side effects, a person's past medical history, the other medications he is taking, and the very personal definition of what it means to achieve an erection satisfactory for sexual activity.
How Viagra and Cialis work

Viagra and Cialis are part of a family of drugs called PDE-5 inhibitors. PDE-5 (phosphodiesterase type-5) is an enzyme that is basically a gatekeeper in the reproductive system: It limits an erection by moving blood out of the penis (through a chain reaction with other molecules).  시알리스  and Cialis work by blocking PDE-5. This maintains elevated levels of a substance called cGMP, which creates relaxation in muscle and encourages blood vessels to dilate. This leads to more free blood flow, even to the penis.
