Pfizer’s new patent for Viagra is set to expire on Tuesday, while the US Food and Drug Administration (FDA) will begin its final review of the drug’s safety and efficacy in clinical trials.
The active ingredient in Viagra, sildenafil, is already available in the US for erectile dysfunction treatment Cialis. Pfizer’s patent on Cialis expires on March 18.
Pfizer and the US Food and Drug Administration (FDA) said in a statement: “These new uses for Pfizer’s Viagra and related drugs are expected to expire on a total of 30 and 2023 basis, respectively, until 2023, while the expiration date cannot be determined until after 2023.”
The sildenafil patent expires in the UK on June 18 and will expire in the US on November 28.
Cialis and the other two erectile dysfunction drugs have similar chemical structures. Cialis was Pfizer’s first prescription medication for erectile dysfunction. It was first marketed in 1998 and was the first drug approved for women. Cialis is the only drug approved specifically for men’s sexual dysfunction and the first drug to win approval from the Food and Drug Administration.
“The expiration of Pfizer’s Viagra patent is a significant milestone in the history of the pharmaceutical industry,” said Dr. Sherwin Jones, chairman and chief executive of Pfizer’s medical research arm. “This is the first time a new patent has been challenged on the basis of safety and efficacy.”
A US Food and Drug Administration (FDA) filing in Europe filing for the generic Viagra will require the FDA to review the drug’s safety and efficacy in clinical trials, Pfizer said in the filing. The agency will likely conduct its review in the US and will then be able to determine if the drug is appropriate for use in Europe.
Pfizer is using a “third party disclosure program,” with drugmakers that provide details about the program and the company that owns and operates the drugmaker. The program will require the company that owns the drugmaker to disclose the program’s details, Pfizer said.
The FDA has been monitoring Pfizer’s use of the drug since 1998 when it was first approved for men with erectile dysfunction. It has not received any reports of adverse events related to its use in men.
The drug will be available to physicians in the US and other countries throughout the world by prescription, or as international prescription drug license (issuance) approval, in roughly 40 countries and territories.

This is due to the fact that men are unable to achieve an erection or perform at all for around 8 minutes or longer in bed. This is because a man cannot sustain an erection for an entire amount of time without ejaculation. Men have tried other drugs to increase their sexual arousal, but none of them have had an erection in as long as the first couple in the bed. Now, it is important to have an erection for at least 4 hours at a time. This will give you more stimulation and give you a better sex drive.
