Cialis (Tadalafil) is a medication known as a PDE5 inhibitor. PDE5 normally causes blood vessels in the penis to return to their normal size, ending an erection. Cialis prevents PDE5 from operating in its normal function, thus extending the time an erection can be maintained.

To take effect, sildenafil can be taken as long as 4 hours prior to sexual activity and as short as 30 to 60 minutes beforehand. The cost of generic sildenafil makes this stand out as an ED medication option
