In a recent interview with the South African Medical Journal, Dr. Michael O'Brien, a board-certified urologist at the University of Witwatersrand, said that he was "disappointed" with the way in which Pfizer, the manufacturer of Viagra, has been hit by a patent for its new drug, Cialis, to the United States. "The world is flooded with generic Cialis, which has never been as strong in comparison to the branded Viagra," O'Brien told the BBC. Pfizer's patent for Cialis was due to expire in April this year but the drug had been available for sale for five years. The company is planning to launch generic versions of Cialis later this year, but is waiting for the arrival of an FDA advisory panel to weigh in on how to treat the erectile dysfunction problem.
"What's sad is that Cialis is a very expensive drug, but it's still being used as an erectile dysfunction treatment," said O'Brien, who runs a pharmaceutical company based in Johannesburg. "The problem with Cialis is that it has not been shown to have any potential to cause sexual side effects. This is because the mechanism by which Cialis works in the body is not yet understood. It can still cause a side effect but not be a sexual problem."
A Pfizer patent for Cialis expired in March 2008 and is now in its last stages. The drug, which is indicated for treating erectile dysfunction, costs about $1.5 million per year. In November, the World Health Organization reported that more than 90 million men globally are affected by this condition, and that Cialis will become available for a further two-thirds of those men. Despite this, Cialis remains the top selling drug in South Africa, with over 60% of the population reporting erectile dysfunction.
"I was very disappointed by Pfizer's decision," O'Brien said. "It's unfortunate that the company has been in a bind and we are still waiting for the approval of its version of Cialis for the United States."
He said the decision to offer Cialis for sale was not the only reason for the company's setback. A new drug, Viagra, has also proved an intriguing idea, said Dr. Paul Bessheer of the University of Cape Town's department of urology, "but it's also not a first for the pharmaceutical company."
Cialis is also the second most-used drug in the world for impotence treatment, and in 1998 it was the second-most-used drug in Europe. It is the third-most-used drug in the world with a sales of over $3 billion annually in the European Union.
In South Africa, Pfizer is the largest manufacturer of prescription drugs in the world and the largest manufacturer of branded drugs. The company has already invested millions of dollars to develop the next generation of drug-makers. However, the company has not yet decided whether to launch its product for South Africa to the United States.
"Cialis is a relatively new drug that is very expensive, very expensive to produce and we are having a difficult time bringing it to market," said Dr. David Smith, who owns a company in South Africa. Smith is a consultant to Pfizer, who is the company's marketing director, and Smith is the CEO of Pfizer's North American headquarters.
On the other hand, Pfizer is a highly successful company in the world, with a revenue of over $200 million a year. Its sales of $3 billion a year in the United States and $6 billion in Canada are estimated to be spent on Viagra and Cialis. The Pfizer patent for Cialis expires in April 2008 and the company is still waiting for the FDA advisory panel to weigh in on how to treat the erectile dysfunction problem.
