    Tadalafil is the main ingredient in Cialis and is a type of PDE5 inhibitor. Tadalafil is also available as a generic medicine under the same name. It works by limiting the activity of enzymes, and increasing blood flow to the penis to improve erectile potency. Erectile dysfunction is an area of medicine which has seen significant development over the course of the past decade. From 1998 to 2002, there were only two treatments available for the condition (one of which is now a household name) before a handful of others emerged in years that followed. Cialis was released onto the market by Lilly in 2003, and has since been available to buy online with a prescription.
