Endo Receives FDA Approval for New Percocet(R) Strengths





Reduced Acetaminophen Should Ease Concern About Daily Acetaminophen Limits




Chadds Ford, Pa., November 26, 2001 -- Endo Pharmaceuticals
Holdings Inc. (Nasdaq: ENDP; ENDPW) today announced the Food and Drug
Administration's approval of the abbreviated new drug application to market
Percocet(R) 7.5/325 and 10/325 oxycodone/acetaminophen tablets that was
filed by Endo Pharmaceuticals Inc., a wholly owned subsidiary of Endo
Pharmaceuticals Holdings. Percocet(R), the leading brand of
oxycodone/acetaminophen on the market, is indicated for the treatment of
moderate to moderately severe pain. The new reformulated Percocet(R)
7.5/325 and 10/325 strengths offer proven pain relief with reduced
acetaminophen content as compared with previously available formulations of
the pain-relieving drug.


Carol A. Ammon, president and CEO of Endo Pharmaceuticals stated,
"The new reformulated Percocet(R) 7.5/325 and 10/325 underscore the
strengths of Endo in the marketplace. We believe that we have a a robust
pipeline that feeds into our growing marketing and sales organization, and
the gold standard in pain management with our Percocet(R) products.


"These new formulations were developed in response to physician
demand. These formulations combine the higher strengths of 7.5 and 10
milligrams of oxycodone that physicians have increasingly adopted, with up
to 50% less acetaminophen per day than previous formulations. This
reinforces Endo's commitment to providing a broad range of safe and
effective pain management products," Ms. Ammon said.


"With this new formulation, physicians can still take advantage of
the synergistic action of the two analgesics combined, but without worrying
about exceeding the daily limit of acetaminophen," said Nathaniel Katz, MD,
Assistant Professor of Anesthesia at Harvard Medical School. "This will
really be helpful to patients who may need higher doses of oxycodone to
relieve their pain."


The new reformulated strengths, which are expected to be available
in pharmacies within the next week to ten days, will potentially enable
patients to take their Percocet(R) on a simpler dosing schedule, allowing
them to take fewer tablets per day, and less frequently than the original
5mg tablet. And due to the lower acetaminophen levels, these new strengths
may allow physicians to prescribe Percocet(R) 7.5/325 and 10/325 for more
long- term use than previously acceptable.


"The new strengths continue to deliver the dual benefits of
oxycodone and acetaminophen, while lowering the risk of excessive
acetaminophen exposure," said Lori Reisner, Pharm.D. and Associate Clinical
Professor of Pharmacy at the University of California in San Francisco.
"The ever-increasing number of acetaminophen-containing products and other
over-the-counter pain relievers requires pharmacists to be diligent in
reminding physicians and patients about the appropriate level of usage."


The most frequently reported side effects of Percocet(R) include
lightheadedness, dizziness, sedation, nausea and vomiting. Oxycodone can
produce drug dependence and has the potential for being abused. Physicians
are reminded that the total daily dose of acetaminophen must be carefully
considered in the use of any combination product. For complete prescribing
