FDA STRENGTHENS WARNING LABEL FOR
PROPULSID
FDA is advising doctors about new warnings of cardiac
problems associated with the drug Propulsid (cisapride), a
treatment for nighttime heartburn. FDA's warning is being issued
in conjunction with a "Dear Healthcare Professionals letter" from
the drug's sponsor, Janssen Pharmaceutica of Titusville, NJ. The
drug's labeling has been revised to include new information about
the cardiac risks associated with the drug and to recommend that
other therapies for heartburn generally be used before
Propulsid.
These actions were prompted by reports of serious adverse
reactions -- including heart rhythm disorders and deaths
associated mostly with the use of the drug in people who were
taking certain other medications or who had particular underlying
medical conditions. From 1993 to 1998 there were 38 reports of
deaths in the U.S. Nevertheless, FDA cannot directly link
reported deaths to the drug.
The "Dear Healthcare Professionals letter" and revised
labeling for Propulsid emphasize that the drug should not be used
in patients taking certain antibiotics, antidepressants,
antifungals, protease inhibitors, or various other drugs. The
strengthened warnings also contraindicate the drug's use in
patients with certain disorders--such as congestive heart
failure, multiple organ failure, chronic obstructive pulmonary
disease which causes serious respiratory problems, and advanced
cancer. Propulsid should also not be administered to patients
with electrolyte disorders (hypokalemia or hypomagnesemia).
These include patients with severe dehydration, vomiting,
diarrhea, or malnutrition, or those taking potassium-wasting
diuretics and/or insulin in acute settings, or who might
experience rapid reduction of plasma potassium.
Furthermore, because of the risks associated with the drug
and the many factors that need to be considered when properly
administering it, doctors are being advised that Propulsid should
usually be used in patients who have not responded adequately to
lifestyle modifications or other drugs for treating nighttime
heartburn due to gastroesophageal reflux disease.
Propulsid's current labeling states that the drug's use
should be discontinued if relief from nighttime heartburn does
not occur. The labeling further specifies that the minimum
effective dose should be used and recommended doses should not be
exceeded. It is also recommended that the daily dose be halved
in patients with reduced liver function.
Propulsid was approved by the FDA in tablet form in 1993,
and in suspension form in 1995 after 23 months of review.
Health care providers should report any adverse events
related to Propulsid to Janssen Pharmaceutica (800-526-7736) or
to FDA. Reports may be submitted to FDA by telephone
(800-332-1088), by fax (800-332-0178), or by mail using a postage
paid
MedWatch form from the back of the Physicians Desk Reference.
The MedWatch report should be mailed to:
