Current quotes (delayed 20 mins) PFE 106 5/8 0 (0.00%) NEW YORK, May 28 /PRNewswire/ -- Pfizer Inc. said today that it
had reviewed the deaths of patients who had received Viagra (sildenafil
citrate) and that as a matter of routine practice had discussed the
cases with the U.S. Food and Drug Administration.Pfizer is making no
changes to the Viagra product label. Pfizer believes that the
information available in the cases does not suggest any risk to patients
which is not already described in the product label or known for the
population being treated with Viagra. From available information, it
appears that these cases were attributed to either cardiovascular events
associated with sexual activity in older men or a combination of Viagra
and nitrates, which is contraindicated in the FDA-approved label.FDA
reviews similar reports for all approved prescription pharmaceutical
products. These reports are carefully reviewed to assure that the
labeling for the product adequately expresses both the risks and
benefits for the product. As with any new drug, if new benefit or risk
information related to the use of Viagra becomes available, it will be
communicated to the medical community.In placing the safety of Viagra in
perspective, Pfizer noted that statistics from the National Center for
Health Statistics show that the underlying rate of death from all causes
in men over 45 is almost 1,600 deaths per million per month. The
American Heart Association has estimated that the male mortality rate
from cardiovascular disease is 185 to 275 cases per million on a monthly
basis.More than 1 million prescriptions for Viagra have been written
since the drug's approval on March 27 for the treatment of erectile
dysfunction. Pfizer said that more than 80 percent of prescriptions to
date have been for men over the age of 50 years.Pfizer said the safety
and efficacy information reported since approval is consistent with the
clinical trial experience that was the basis for FDA approval.
