What is tadalafil?

Tadalafil is the chemical name of the active ingredient in Cialis®. Cialis® was originally patented and sold by Eli Lilly. It is FDA-approved to treat ED and urinary symptoms due to BPH. After the patent expired in 2018, the FDA gave permission to other drug companies to manufacture a generic version of Cialis®. The FDA requires generic drugs to be bioequivalent to the brand name version. This means that they act the same way in the body and are expected to produce the same effects as the original brand name drug. Generic drugs are generally much cheaper than the original brand name drug, and most drugs prescribed in the US are generic.
