`New drug lifts PfizerMarch 27, 1998: 3:42 p.m. ET
`Drug company's shares rise on FDA approval of pill to treat impotence
`NEW YORK (CNNfn) - Shares of pharmaceutical giant Pfizer Inc. were pushed higher Friday on
`news that the U.S. Food and Drug Administration has approved its treatment for impotence.
` Pfizer stock (PFE) was 5/16 higher at 94-11/16 in late-afternoon trading. The shares have risen
`strongly from about 75 since the beginning of the year.
` Pfizer's drug, marketed under the name Viagra, is the first pill to treat the condition which
`affects millions of men in the United States.
` The drug acts by enhancing the muscle-relaxing effects of nitric oxide, a chemical normally
`released in the body. The relaxation allows the increased blood flow necessary for normal sexual
`function.
` Viagra was evaluated by more than 3,000 men in clinical trials with varying degrees of
`impotence caused by diseases such as diabetes, spinal court injury or prostate surgery.
` In all trials, men on Viagra reported success more often than on placebo. Among the most
`common side effects were headache and indigestion. About 3 percent also reported changes in
`vision, mainly altered color perception.
` Shares of Pfizer competitor Vivus Inc. (VVUS) were also up 7/8 to 11-1/16 on the news. Vivus
`manufactures Muse, a prescription suppository for treatment of impotence.
