`
`NEW YORK -(Dow Jones)- The Food and Drug Administration Friday announced approval of a long-awaited
`impotence drug, Pfizer Inc.'s Viagra, which is the first pill for the disorder.
`
`With a potentially huge market, the drug is expected to become a big seller for Pfizer. Arvind Desai, an analyst who
`follows the company for OrbiMed Advisor, said sales could reach $1 billion the fifth year after launch.
`
`Some analysts are even more optimistic, saying the drug could become a household name like the antidepressant
`Prozac and ring up sales of $2 billion or more annually. Last week, William C. Steere, Pfizer's chairman and chief
`executive, told The Wall Street Journal the drug may help Pfizer top Merck & Co. as the biggest seller of
`prescription medicines in the world.
`
`The company said in the U.S. alone, 20 million to 30 million men suffer from some form of impotence.
`
`But as with Prozac and the recent wave of diet drugs, there's a chance Viagra will find its way into the hands of a
`lot of people who don't need it medically but think it will make their sex lives better anyway. That possibility troubles
`medical ethicists.
`
`Expected to hit the market around mid-April, the drug went through the FDA's application process in less than six
`months. The drug isn't approved anywhere else in the world.
`
`Viagra doesn't work like other treatments, which can include injections, suppository-like devices or even surgery.
`Generically called sildenafil, the drug was first tested to fight angina, the painful heart condition caused by
`constricting or clogging of heart arteries. That didn't work, but the men in the study reported having better erections
`than before.
`
`As an impotence drug, Viagra is taken an hour or so before a sexual event. Once a man's brain kicks into gear as
`he becomes aroused, Viagra works subtly to amplify the effects of erection-promoting chemicals in the penis.
`
`In heart patients, sildenafil was supposed to treat angina and hypertension by blocking the action of an enzyme,
`phosphodiesterase, that is believed to tighten muscles lining blood-vessel walls. Researchers soon discovered that

`
`while the drug wasn't very good at thwarting the heart enzyme it homed in on a different form of the same enzyme
`that is present mainly in the penis.
`
`Pfizer, which got the blessing of the Vatican for the drug because it can enhance marital relations, tried to dissuade
`people into thinking that Viagra is a "love drug" that will boost one's libido.
`
`"Viagra works in response to sexual stimulation," said Joseph Feczko, M.D., Pfizer's senior vice president for
`medical and regulatory operations. "It has no properties of an aphrodisiac and does not stimulate fantasy."
`
`Also, the FDA warned that it shouldn't be taken more than once a day. Some side effects include headache,
`flushing, indigestion and altered color perception.
`
`Pfizer tested Viagra on 4,000 men. The drug was 70% effective across patients with impotence caused by
`diabetes, spinal cord injury or psychological causes, among others.
`
`Patients are advised not to take the medication with organic nitrates, such as nitroglycerin patches or sublingual
`tablets, because the combination may lower blood pressure.
`
`Pfizer said Viagra should be available with a prescription by mid-April at a wholesale price of $7 a tablet.
`
`In composite New York Stock Exchange trading Friday, Pfizer shares (PFE) climbed $1.375 to $95.75 in active
`trading.
