Cialis, a medication for erectile dysfunction and benign prostatic hyperplasia, generated significant sales in the United States. While specific revenue figures for Cialis sales in the US are not publicly detailed by manufacturer Eli Lilly and Company in readily available reports, the drug has historically been a substantial contributor to the company's revenue. Its over-the-counter availability in some markets has also impacted sales channels.
When Did Cialis Go Off-Patent in the US?
Cialis's (tadalafil) U.S. patent protection expired, allowing for the introduction of generic versions. The primary patent for Cialis expired in September 2018. This marked a significant event, typically leading to a decrease in brand-name sales as generic competitors enter the market [1].
What Are the Generic Versions of Cialis?
Following the patent expiry, generic versions of tadalafil became available in the United States. These generic alternatives offer the same active ingredient and are manufactured by various pharmaceutical companies.
How Do Generic Cialis Prices Compare to Brand-Name Cialis?
Generic tadalafil is generally priced lower than brand-name Cialis. The introduction of generic competition typically drives down prices for consumers seeking treatment for erectile dysfunction or benign prostatic hyperplasia.
What Are the Main Uses of Cialis?
Cialis is prescribed for two primary medical conditions: erectile dysfunction (ED) and symptoms of benign prostatic hyperplasia (BPH). It is also sometimes used to treat pulmonary arterial hypertension under the brand name Adcirca, though this is a different indication and formulation [2].
Who Manufactures Cialis?
Eli Lilly and Company is the original manufacturer of Cialis [1]. Following patent expiry, other companies have begun producing and marketing generic versions of tadalafil.
