The company behind Viagra and Cialis is expanding into other areas. Viagra’s maker, Pfizer, is looking for a partner for its Cialis product portfolio.
Apotex, Teva Pharmaceutical Industries and Sun Pharmaceutical Industries have signed a deal that could see the two companies partner with Teva, as well as a generic partner. The Cialis deal could create an opportunity for Teva to build a leading product line in Cialis, while also offering another layer of competition.
The announcement comes on the heels of Pfizer’s Viagra patent expiring this year. However, other than its recent announcement in U. S. District Court that it would start marketing its drug in December, Cialis has not had a patent expiring earlier than the last decade, according to Pfizer.
For example, Cialis patent expirations for Sildenafil citrate (known as Viagra) and tadalafil (Cialis) from 2010 to 2017 resulted in a 6.3% decline in revenues, while sales of Cialis fell 0.9% and 3.9% respectively.
This is a significant opportunity for Pfizer and Teva, as they have been pushing for more research in this area, and the combination of this with the company’s upcoming patent expiry may offer some additional competition. It’s also possible that the company could develop a product that doesn’t have generic competition in mind.
Viagra’s patent expires in 2017, while Cialis’ patent has expired in 2019. Both companies are looking to create a product with a lower generic price, and Teva could consider developing a generic version of the erectile dysfunction drug if Cialis does not offer the same level of competition as Viagra.

Product descriptionThese tablets contain Sildenafil citrate, a prescription-only medication used to treat erectile dysfunction (ED) in adult men. Erectile dysfunction is a common sexual health issue that affects millions of men worldwide. It is characterized by the ongoing inability to achieve or maintain an erection that is firm enough for sexual activity. ED is typically caused by a lack of blood flow to the penis, which may lead to difficulty in achieving or maintaining an erection. ED can have a significant impact on a individual’s self-esteem and quality of life. By taking these tablets, you are not prescribed a medication to treat your health condition. Taking Viagra or other ED medication with PDE5 may have resulted in low blood pressure, and some men may experience dizziness, fainting, or even a rapid heartbeat. It is important to discuss the facts with a doctor and to take Viagra or other ED medication as they may cause any side effects or interactions with other medications.
