The company behind erectile dysfunction treatments Viagra and Cialis have said they will soon be making a similar decision for their other business, sildenafil citrate.
The two products, which have been the subject of controversy over sexual performance issues, are among those to be marketed by Cialis, the drug company that will be selling the two products in the United States. The erectile dysfunction medicine has been nicknamed Viagra and Cialis, because they contain the active ingredient sildenafil citrate.
Cialis, which is now in the United States, will sell sildenafil as a lower dose, about 60 milligrams, which is equivalent to four Viagra pills.
Viagra, which is available on prescription, costs about $1 a pill, making it the highest dosage of the three.
Viagra also has a higher dosage of the drug that can be taken just before sex, and Cialis comes in a gel form that is easy to rub in and can be applied directly to the penis.
Sildenafil, the active ingredient in Cialis, is used for treating the symptoms of pulmonary arterial hypertension, or high blood pressure in the lungs.
Cialis is available by prescription only, and will be sold in the United States through a network of licensed pharmacies that operate in states such as Texas, Florida and Florida Atlantic.
The companies said that the two products will come into competition in the US market in the next three to six months, and will possibly sell in the same way as Viagra.
The companies have already submitted applications to the Food and Drug Administration asking for approval for their drugs in the second and third-place markets, and Cialis will be sold in a similar way to Viagra.
The two drugs are also available as an oral medication in the United Kingdom, or as a treatment for male sexual arousal disorder, or Sildenafil Heart attack.
The FDA has rejected applications for sildenafil and it is not known how much of a profit Cialis will make from these sales.
Cialis' sales have been hampered by a decline in its patent from the late 1990s to mid-2000s, and the company has been forced to lose a major share of the global pharmaceutical industry to the pharmaceutical companies, who have been accused of trying to copy Viagra and Cialis.
The company's patent on sildenafil has expired, and in May it will now be sold in the US.
Viagra, which is still being developed, is still available in several other markets, including the UK, while Cialis is available in a gel form for those who prefer the blue colour.
Cialis is said to be based in Australia, but the company is also based in Spain, but has been unable to obtain a licence for the business since a Spanish judge ruled that the drug should not be sold in the EU in the first place.
Sildenafil, the active ingredient in Viagra, has been nicknamed Viagra and Cialis because they contain the same active ingredient.
Shares of Cialis were up 3.5% in afternoon trading, up from a low of $30.40 in late-morning trading on the New York Stock Exchange, as the stock is traded less frequently.
Cialis (tadalafil) (L) has been available to buy from pharmacies in Australia and New Zealand, and it is based in the United Kingdom.The erectile dysfunction medicine has been nicknamed Viagra because it contains the active ingredient sildenafil citrate, and Cialis was nicknamed "the weekend pill" by its manufacturer, Pfizer, who was also the manufacturer of Viagra.
Pfizer said its application for its erectile dysfunction product has been granted an FDA approval, and that it will begin selling the medicine in the US in the second week of December.
A New York judge ruled in December that the drug sold in the US in the second week of December was not safe for use in the US, and that the company was not under an obligation to do so.
Pfizer said it was disappointed with the decision, but was committed to working with the FDA to approve the product.
The three companies will work with the FDA to approve the erectile dysfunction medicine.
The drugs are available as a generic, priced at around $16 a tablet, but Cialis will have a lower price of about $5 compared to Viagra, and is priced between $1 and $3 a tablet.
WASHINGTON - The pharmaceutical industry has been accused of overcharging for Viagra, the generic drug of the popular erectile dysfunction drug, and not disclosing the results.
The company's new report shows that the FDA has asked drug manufacturers to disclose the side effects of the drug. That could be a turning point for Pfizer, the world's biggest drug maker, which is expected to be up and down on the issue in coming weeks. Pfizer will face lawsuits over its sales of Viagra.
The companies are facing lawsuits by thousands of men who suffered from erectile dysfunction and other conditions linked to the drugs. But Pfizer said in a statement that it plans to make the drug available as a generic in the United States, "for the treatment of erectile dysfunction."
The company said the settlement will cost consumers $4.50 a month for a three-month supply of Viagra and $3.75 for a three-month supply of Cialis, which was sold by Eli Lilly and Company for $4.93 a month. A separate statement from Pfizer said it would offer free, "full-service" alternatives to Viagra, but that the company will still require consumers to have a copy of the information.
According to a statement from the company, the company will not comment on its own sales estimates or on Pfizer's own data.
In a statement, Pfizer said it has "been assured by the FDA and consumer advocates that the drug is safe and effective for the treatment of erectile dysfunction." The company also said that it is "researched" and "reviews" the safety and efficacy of Viagra.
The company is "reviewing all available available data to ensure the product is safe and effective for the treatment of erectile dysfunction," the statement said. "Pfizer is committed to continuing to work closely with our partners to ensure that all available data is accurate and current."
Viagra is used to treat the symptoms of erectile dysfunction, which is the inability to get or keep an erection firm enough for sexual activity. Viagra belongs to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors.
Viagra works by relaxing the smooth muscle cells in the penis, allowing blood to flow into the penis when a man is sexually aroused. It helps men get and keep an erection that's hard enough for sexual activity. The drug also helps men last longer in bed, helping them to be ready for sex the next day.
Pfizer said that the FDA has not found any studies of the drug to be linked to any adverse effects. The company also said that it is reviewing other drug data that may be released after Pfizer completes its studies.
Pfizer is looking into whether the company has enough data to justify using other company drugs for the drug, including some that are already on the market.The Food and Drug Administration says the drugs are safe and effective and have no known side effects. The FDA has not approved Viagra for sale or for sale, but the drug can cause headaches, dizziness, and flushing. It can also cause vision problems, such as fainting. The company has not issued a statement telling consumers it is reviewing the information. Pfizer is not releasing any updates on its safety or side effects.The companies are still reviewing the data and are working with FDA on possible side effects, the FDA said. "The Food and Drug Administration is committed to working closely with our partners to ensure the information presented is accurate and helpful to consumers."
In a statement, Pfizer said it has not received any reports of any adverse events related to the drug or related medications. It did not return calls and messages seeking comment.©2025 The National Academies Publishing Group
