WASHINGTON – Viagra maker Pfizer Inc., the world’s second-biggest drug maker, is poised to lose its patent protection, after a study found that it will be able to get off the patent it developed.
Pfizer had planned to take a step to get off patent, but the company is now forced to revise its plans, saying it can’t get the patent it originally developed for the impotence drug Viagra.
The US Food and Drug Administration said Friday that it had found that Pfizer could gain up to 80% of the market share needed to sustain its patent for the erectile dysfunction drug.
But the FDA’s latest warning comes from a study that showed the drug had a higher likelihood of causing birth defects, birth defects in the developing baby, and heart problems.
The study, published in the journal BMJ, showed that a baby taking the drug died in the first three months after birth. The baby was born with a brain tumor and a heart defect, and was later found to be rare.
The FDA also warned that it was the first study in which the drug was shown to cause an increased risk of breast cancer and birth defects.
But the agency said the research showed the drug was not approved for use in women. In the United States, the drug was approved in 2013 for treatment of erectile dysfunction.
Pfizer said that while its study found that the drug was associated with a higher likelihood of birth defects, it also showed that the drug had a similar effect in the developing male baby.
It was the second time the FDA had warned about possible birth defects in a drug and warned that it could lead to heart attacks or strokes.
The drugmaker said it was not selling Viagra but would sell the drug for $1 a pill and have an offer sent out for Pfizer.
Pfizer said Friday it was consulting with a US health regulator to examine the data.
“We are aware of this issue and are in discussions with our regulatory agencies to ensure that the regulatory decisions we make in our patent litigation are being respected, and that we can continue to evaluate this issue,” Pfizer said in a statement.
The company declined to give a timeline for when it would seek to sell Viagra.
In a statement Friday, Pfizer said that in 2010 it had received FDA approval for the treatment of erectile dysfunction, which is a serious condition that requires immediate medical attention.
It was also approved for other purposes, including the treatment of pulmonary arterial hypertension.
Pfizer also is working with the FDA to develop a drug that would help people get or maintain an erection.
The company said that while its studies showed that Viagra had similar effects in the developing male baby, it also showed that the drug had a higher likelihood of causing birth defects.
Pfizer had planned to take a step to get off patent, but the company now has to revise its plans, saying it can’t get the patent it developed for the drug until the agency takes a final decision.
Pfizer’s plan to take a step to get off patent is based on its study that showed the drug was associated with a higher likelihood of birth defects, birth defects in the developing baby and heart problems.
The FDA, however, said Friday that it had found no cases of birth defects in the developing male baby.
The company said that while its study found that the drug was associated with a higher likelihood of birth defects, it also showed that the drug had similar effect in the developing male baby. The FDA said that the study showed the drug was not approved for use in women.
Pfizer, which is based in New York City, said that while it has not sold Viagra in the US and has not approved any drug for erectile dysfunction, it has made an offer for it.
The company said Friday that it has made a phone call to the FDA and has reached out to Pfizer to have it changed.
In an email to The Associated Press, Jeffery O'Dell, director of marketing at Pfizer, said the company is working with the FDA and will be evaluating the data and changing its plans.
“Pfizer is taking a step forward in its attempts to seek approval to market an impotence drug. Pfizer has always been committed to bringing new and innovative treatments to men who suffer from erectile dysfunction.

A new Viagra-style tablet for women is making its way into the market. It's been on sale in the UK for nearly four years, and now it's here to stay.
Female Viagra pills are an innovative form of medication. They work by increasing blood flow to the genitals, which is particularly helpful for women who have low levels of sexual desire. It's designed to be taken before sexual activity but it can be purchased in bulk. It's also available over the counter.
Unlike pills, Viagra-style tablets work on its own, and they don't contain any chemical or hormones. So unlike pills, they don't have a doctor's prescription. So when the pills are taken before sexual activity, they don't affect the genitalia. Instead, the active ingredient is absorbed into the bloodstream and is taken directly into the vagina. This helps you have more spontaneity.
The Viagra-style tablet has a low profile. It's often sold online but it's not widely available. It's available only by prescription and it can only be purchased from the pharmacy.
