ED, also known as impotence, is a common problem that affects millions of men worldwide.
A German court has upheld a suit by British company Pfizer to stop marketing Viagra, saying it was too expensive and not enough to meet the demand. The suit was filed by Pfizer, which had been selling the drug for more than $1 billion in the US in 2013.
The British-based company, which has suffered a price cut in the US in 2013, is hoping the decision will help it expand into the market more. It will be able to make a profit of up to $1.5 billion on sales by next year.
Viagra, or sildenafil citrate, is the brand name for the drug Viagra.
Pfizer, the world’s largest maker of generic drugs, is planning to launch its generic version of Viagra on Wednesday.
The suit against Pfizer, which bought the US rights to the drug last year, said it was too expensive and that it had not enough market power to meet the demand.
The suit said Pfizer had already paid a “loss” to American patients for the drug from 2013 to 2014 and had been forced to pay into the US market, which was the world’s largest, because of price cuts.
The suit also said the drug was in the US market because of a number of other conditions.
“Pfizer’s decision to halt selling Viagra was part of a wider trend towards increasing competition and market size,” the suit said. “It was also part of an attempt to increase the number of patients who may be affected by price cuts or have had previous adverse events related to their use of the drug or have had side effects or drug interactions.”
The suit added that Pfizer had been trying to expand its market share to include patients in the US. The firm said it was planning to launch its generic version of Viagra on Wednesday.
It said Pfizer had not paid any attention to the US market for the drug until it was “very close to a complete settlement.”
Pfizer’s latest US patent on its erectile dysfunction drug Viagra has been in force since the US Food and Drug Administration approved the drug last October. It has been subject to a final approval process.The suit said the company had been trying to expand its market share to include patients in the US by increasing its overall share by 20% to 40%.
The suit said Pfizer’s recent decision to launch Viagra to US patients “does not address the issue of cost savings and should not be viewed as a price-fixing effort by the company or a deliberate attempt to expand its market in a way that will increase its share.”
The suit also said Pfizer had paid a “loss” to American patients “for the use of the drug, which was not disclosed in the US patent.”
Pfizer has denied the suit and said the company had “engaged in a deliberate and unlawful price-fixing conspiracy” in order to extend the patent on the drug. The company has also denied all allegations that it had made false or misleading claims about the drug and has denied all allegations that the drug was not made for the treatment of erectile dysfunction. Pfizer, which has had the drug for more than a decade, is seeking to stop selling the drug in the US.
In its US patent, the court ruled that Pfizer’s use of the drug was “not a sufficient basis for deciding that the drug is of a therapeutic use” and that it was not “a substantial advance in the field of pharmaceuticals or of health care”.
Pfizer’s patent on its erectile dysfunction drug Viagra has been in force since the US Food and Drug Administration approved the drug in 2012. It is the first time the US Food and Drug Administration has approved a drug to treat the condition.In its complaint, Pfizer said the drug had been used to treat “male erectile dysfunction” for more than 40 years and had no known adverse effects.
“The use of Viagra in this manner is a violation of the Federal Food, Drug and Cosmetic Act and a blatant violation of the human rights of the United States,” the company said in the complaint.
