Cialis (Tadalafil) is in a class of drugs called phosphodiesterase inhibitors that also include Sildenafil (Viagra) and Vandenafil (Levitra). FDA approved Tadalafil – Cialis in 2003 for the treatment of men who experience sexual problem like difficulty having and maintaining an erection.
Cialis (Tadalafil), an oral treatment for Erectile Dysfunction (ED) in men, is a selective inhibitor of cyclic quanosine monophosphate (cGMP) - specific phophodiesterase type 5 (PDE 5).
Cialis is available in the form of tablets which contains 5, 10 or 20 mg of Tadalafil and inactive ingredients like croscarmellose sodium, hydroxpropyl cellulose, hypromellose, iron oxide, lactose monohydrate, magnesium stearate, microcrystalline cellulose, sodium lauryl sulphate, talc, titanium dioxide and triacetin.
There are variants of Cialis available in the market – they are called generic Cialis or generic Tadalafil. They have the same composition as the branded Cialis. The generic drug may look different because in the US, FDA does not allow it to look the same. Colors, flavors and certain other inactive ingredients may be different.
Apacalis or Forzest or generic Tadalafil, all are forms of generic Cialis. Experts say that there is nothing as generic Cialis and one should be extremely careful before buying any of these. Before buying generic Cialis check three to four web sites to ensure that you are getting the right product and the right price.
Forzest is manufactured by Ranbaxy and has the same composition of Tadalafil as Cialis. It is generally available as generic Tadalafil. It claims to work as well as Cialis.
Like Cialis, generic Cialis or Forzest can cause side effects. These effects are usually mild to moderate and usually don't last longer than a few hours. Some of these side effects are more likely to occur with higher doses.

Less common side effects that may occur are temporary changes in color vision (such as trouble telling the difference between blue and green objects or having a blue color tinge to them), eyes being more sensitive to light or blurred vision. In rare instances, men have reported an erection that lasts many hours. You should call a doctor immediately if you ever have an erection that lasts more than 4 hours.
