Book excerpt: Introduction Cialis is the brand name for tadalafil, a prescription used to treat ED (Erectile Dysfunction). It's in a class of medications called phosphodiesterase-5 (PDE5) inhibitors. Cialis and non-exclusive Cialis (tadalafil) are taken as an oral tablet, either as a low portion day to day drug or as a higher portion "on-request" prescription. The primary ingredient in both generic and brand-name tablets is the same, but their overall chemical compositions are slightly different. However, they are both equally effective. The price is the main difference.
