Tadalafil is currently protected by a patent that prevents a generic form of the drug from being manufactured. Once tadalafil goes off patent, several companies are expected to start manufacturing a generic version of this drug. The patent for tadalafil expires in 2016.
Tadalafil (Cialis®) is a prescription drug that is licensed for treating erectile dysfunction (ED). It is also approved for treating enlarged prostate symptoms. Tadalafil is manufactured by Eli Lilly and is currently protected by a patent that prevents a generic tadalafil from being manufactured.
(Please note that this article refers specifically to Cialis, the original tadalafil product that is approved for treating erectile dysfunction and enlarged prostate symptoms. For information about the tadalafil product used to treat pulmonary arterial hypertension, please see Generic Adcirca.)
No. Tadalafil is the active ingredient in Cialis, not a generic version of the drug. Although people often refer to a drug's active ingredient as its "generic name," the generic name of a drug is different than a generic version of it. In order for there to be a generic version of a medicine, the original medicine must have gone off patent and another company (besides the original manufacturer) must have made the product.
The first patent for tadalafil expires in 2016. It is expected that once tadalafil goes off patent, several companies will begin manufacturing a generic tadalafil drug.
