Pfizer’s Viagra has been nicknamed the “little blue pill” by a generation of physicians and researchers. And while Viagra’s name is often associated with older men, the company has been using the drug for its brand since 2000. It is being used by men with erectile dysfunction to help them get and keep an erection. It has also been used to treat other problems with aging men, including Alzheimer’s disease.
This week, Pfizer announced that it was promoting the drug for use in men with prostate cancer and benign prostatic hyperplasia, the conditions caused by cancer in men after they have undergone radiation to the prostate.
The FDA is requiring Viagra to be available in the United States, a common form of advertising, and to be taken by men aged 55 and older.
In December, the company announced it would offer Pfizer exclusive rights for the drug from the beginning of 2017, following the expiration of patent protection in 2020. Pfizer’s Viagra has been used in men to treat erectile dysfunction for over a decade.
“We are thrilled to have this opportunity to make Viagra available as an affordable and effective treatment option for men, and to help men maintain an erection that they can enjoy again,” said Dr. John R. Dole, M. D., chairman of urology at Pfizer. “We’re very pleased that Pfizer has chosen to work with its U. S. and Canadian partners to offer this product for sale, and to explore other markets.”
In the same year, Pfizer also received approval from the U. Food and Drug Administration to begin selling Viagra, which is a generic version of Pfizer’s impotence drug Cialis.
Viagra is a medication that is used to treat erectile dysfunction in men. It works by relaxing the smooth muscles in the walls of blood vessels in the penis, allowing for increased blood flow and the ability to achieve and maintain an erection. The drug is taken orally and is available as a tablet, a capsule, or an oral solution.
Viagra is manufactured by Pfizer in the United States, with a patent protection of about $30 million. It has a lot of similarities to the Pfizer-Pfizer Cialis patent that was set to expire this year. Pfizer has the same patent covering the U. market, and Viagra is one of the few brands that has not yet expired in the U.
Pfizer says it has received approval from the FDA and is working with its U. and Canadian partners to make Viagra available for sale in the United States. The company is also working with its U. K. and Canadian partners to launch generic versions of Viagra.
“I think it will be great for the consumer to see that Viagra is now available as an affordable and effective treatment option for men, and to help men maintain an erection that they can enjoy again,” said Dr. Dole. “Pfizer’s Viagra has been used by men with erectile dysfunction to treat the condition. It has been used to treat other problems with aging men, including Alzheimer’s disease. Pfizer is pleased to expand our partnership with Pfizer to offer Viagra to men who are suffering from this condition and who want to be sure they can get the medication they need.”
The U. Food and Drug Administration has approved the first generic version of Viagra to be sold in the U. S., which was launched in 1998. Viagra was approved in Europe and the U. by the FDA last year.
According to Dr. Dole, the company’s Viagra has been used for more than 20 years to treat erectile dysfunction in men, including men who have been diagnosed with prostate cancer and benign prostatic hyperplasia.
In January, Pfizer said that it will begin selling generic Viagra in the U. by the end of 2017.
The following additional information has been provided to help you understand the results of your clinical trial:
Sildenafil (Viagra®)
In a randomized, placebo-controlled trial, in which patients were randomly assigned to receive sildenafil (Viagra®, Pfizer) or placebo, a significantly greater rate of adverse events (adverse event rates >7%) was observed in the sildenafil (Viagra®) group compared with the placebo group (7.5% vs. 5.0%, respectively).
Cialis® (Tadalafil®)
In a randomized, double-blind, placebo-controlled trial, in which patients were randomly assigned to receive tadalafil (Tadalafil®) or placebo, a significantly greater rate of adverse events (adverse event rates >7%) was observed in the tadalafil (Viagra®) group compared with the placebo group (3.2% vs. 1.6%, respectively).
Cialis® (Cialis®) (Tadalafil®)
In a randomized, double-blind, placebo-controlled trial, in which patients were randomly assigned to tadalafil (Tadalafil®) or placebo, a significantly greater rate of adverse events (adverse event rates >7%) was observed in the tadalafil (Viagra®) group compared with the placebo group (3.4% vs. 1.1%, respectively).
Dosage and route of administration
In a randomized, double-blind, placebo-controlled trial, in which patients were randomly assigned to receive either dosage form or placebo, a significantly greater rate of adverse events (adverse event rates >7%) was observed in the dosage form group compared with the placebo group (8.6% vs. 3.2%, respectively).
Interactions
In addition to its effect on erectile function, tadalafil has been shown to have little or no effect on the incidence of benign prostatic hyperplasia.
Erectile dysfunction
Tadalafil (Viagra®) is not recommended for use in women, but patients in clinical studies have reported an increased risk of endometrial cancer in women, compared with men taking placebo. The increase in incidence of endometrial cancer in women has been attributed to the effects of sildenafil (the active ingredient) on the growth of the lining of the uterus, a condition that is currently treated with a combination of progestin and a hormone that promotes the development of endometriosis.
It is unknown whether tadalafil is safe for use in women.
Because of the potential risks associated with tadalafil, physicians should be aware of the following potential interactions.
The following are not all possible interactions. You should check with your physician if you are unsure.
