Pfizer Inc. said on Monday that it will not launch the first generic version of its anti-impotence drug Viagra until the FDA approves it as the first of a new class of drugs that helps patients manage erectile dysfunction. The first generic version of the drug was introduced in 1998.
Pfizer's patent for Viagra expired in March 2006 and is now valid in more than 40 countries. Pfizer said that it plans to file for a generic version of the drug soon, but it will need a "significant percentage" of the drug's sales to keep it approved by the FDA. Pfizer said that the drug will be sold by Pfizer under the generic name VIAGRA.
The new drug is the first FDA-approved generic treatment for erectile dysfunction.
Viagra is the first of the new class of drugs to be approved for use in women and is the first drug to be approved for use in men. It works by increasing blood flow to the penis, helping to maintain an erection during sexual stimulation. Viagra and its generic equivalents, sildenafil and tadalafil, are also approved for use in men.
Viagra was the first of the new class of drugs to be approved by the FDA to treat erectile dysfunction in adult women. Viagra was first marketed in 1998 and was the first to be approved by the FDA for women.
"Pfizer's products are designed to address a specific patient population and are not approved for use in men," said Dr. Steven Nissen, medical director of Pfizer's division of cardiovascular medicine.
Nissen noted that Pfizer has filed a complaint with the FDA seeking to stop the generic competition for Viagra. The company said that it has "great confidence" that the FDA will respond to the complaint by filing a lawsuit against Pfizer in June. The lawsuit is pending.
Viagra will be available through a network of pharmacies that include CVS, Walgreens and Rite Aid. Other major U. S. pharmacies that sell generic versions of Viagra include CVS Health and Rite Aid. Pfizer said that it will launch the first generic version of the drug in November. The drug is expected to become available by Dec. 31, 1998, after Pfizer files a complaint with the FDA.
Pfizer and some other drug makers have been trying to force competitors to sell generic versions of Viagra, but regulatory agencies have not acted in a timely manner. Generic competition for Viagra will probably be limited to those markets with a lower number of competing drugs.

A recent study in the Journal of Sexual Medicine found that men who take Viagra or Cialis do not experience any more erections than they did when they were men who didn't take them.
The study, published in the International Journal of Sexual Medicine, was led by researchers from France and the United States.
Viagra is a brand name for sildenafil, the active ingredient in Viagra. Cialis is a type of prescription medicine, but is not approved for men with erectile dysfunction (ED).
It's been used to treat ED in the past, but in recent years it's been used to treat an enlarged prostate. It's also used to treat benign prostatic hyperplasia (BPH), a condition in which the prostate gland becomes enlarged.
The study was published in the British Medical Journal, but it wasn't the first study to examine ED among men who take Viagra or Cialis.
Researchers in France were led by Professor Gérard Vigna, who is currently a clinical professor at the Paris Cité School of Pharmacy.
They looked at all patients with ED who had been prescribed Viagra or Cialis in the last three months.
There were no differences in erectile function between patients who were given Viagra or Cialis and those who were not.
However, patients who were given Viagra or Cialis who had an enlarged prostate showed the highest degree of improvement in erectile function, with the least degree of improvement in the ability to get an erection. This is the same group that the French study used to help them with ED.
Viagra was associated with a lower rate of premature ejaculation in men who were also taking Cialis, and a higher rate of ED in men who were not taking the medicine.
Viagra was not associated with any changes in blood pressure, heart rate, or blood pressure values, although it was a lower rate of blood pressure reduction than Cialis. They found that men who were given Viagra or Cialis who had undergone prostatectomy had a statistically higher rate of ED than men who had undergone a prostatectomy, which is not the case for Cialis or Viagra.
Cialis was associated with a higher rate of ED among those who took the drug. However, the results of the study were conflicting. The researchers found that Cialis had an effect in men who had undergone a prostatectomy, but it did not seem to work for men who had undergone a prostatectomy.
However, the researchers noted that Viagra and Cialis were not associated with an increase in the risk of ED among men who used the drug.
Researchers also looked at men who didn't take the drug. They found that those who had been prescribed Cialis or Viagra were less likely to have ED than those who didn't, but they did have a higher rate of ED in those who were taking the drug.
In addition, the researchers found that those who were not taking the drug were not at an increased risk of ED.
The researchers also analyzed patients who were prescribed Cialis or Viagra and compared their risk of having ED with the number of men taking the drug and those who didn't.
Overall, the researchers found that the number of men who used the drug was higher among those who took the drug, with the number of men who were prescribed Cialis and Viagra was the highest among men who took Viagra. However, the researchers found that the number of men who were prescribed Cialis was also higher among those who did not.
The researchers also found that the rate of ED among those who took the drug was higher among those who had undergone prostatectomy.
In addition, the study found that those who had undergone a prostatectomy were more likely to have ED than those who had undergone a prostatectomy, with the study finding that those who had undergone a prostatectomy were more likely to have ED.
The study was sponsored by a group of researchers from the National University of Dezêt to study the effects of Viagra on men with ED.
The researchers are also excited about the future of ED treatment in France, and hope that this study will open up a new chapter in the field.
