Endo Pharmaceuticals to Launch Three New Dosage Strengths of OPANA(R) ER

Intermediate Strengths Provide Additional Dosing Options for Physicians Treating Patients With Moderate-to-Severe Chronic Pain

CHADDS FORD, PA--(Healthcare Sales & Marketing Network)--Mar 3, 2008 -- Endo Pharmaceuticals Inc., a market leader in pain management and a wholly owned subsidiary of Endo Pharmaceuticals Holdings Inc. (NasdaqGS:ENDP ), today announced that the U.S. Food and Drug Administration has approved three new dosage strengths of OPANA® ER (Oxymorphone HCl) extended-release tablets CII. The new strengths -- 7.5 mg, 15 mg, and 30 mg -- will be available on April 1, 2008 and will join previously approved OPANA ER dosage strengths of 5 mg, 10 mg, 20 mg, and 40 mg. An opioid analgesic, OPANA ER is indicated for the relief of moderate-to-severe pain in patients requiring continuous, around-the-clock opioid treatment for an extended period of time. (See Important Safety Information below.)

"The addition of three new dosage strengths of OPANA ER, complementing the currently available strengths, will make it easier for physicians to titrate patients to the optimal level of pain relief," said David A. Lee, M.D., Ph.D., Chief Scientific Officer. "The new strengths will also facilitate clinicians' ability to convert patients to OPANA ER from other opioid analgesics to which they may not have had an adequate clinical response. Further, the introduction of these new strengths underscores Endo's long-term commitment to the OPANA franchise and to providing physicians with additional treatment options for their appropriate chronic pain patients."

The approval is based on studies demonstrating the safety and efficacy of OPANA ER in its four original strengths. Because the new dosages fall between the available strengths, FDA did not require new safety or efficacy studies.

About OPANA ER Tablets

OPANA ER tablets were formulated using Oxymorphone hydrochloride, a semisynthetic, pure µ-opioid agonist that had been available previously only as an injectable formulation. The product has been proven to achieve effective relief in multiple moderate-to-severe chronic pain models, in opioid-naïve and opioid-experienced patients. All OPANA ER strengths are available by prescription only.

Important Safety Information

OPANA ER is an opioid agonist and Schedule II controlled substance with an abuse liability similar to morphine. OPANA ER can be abused in a manner similar to other opioid agonists, legal or illicit.


OPANA ER contains Oxymorphone, which is a morphine-like opioid agonist and a Schedule II controlled substance, with an abuse liability similar to other opioid analgesics.

Oxymorphone can be abused in a manner similar to other opioid agonists, legal or illicit. This should be considered when prescribing or dispensing OPANA ER in situations where the physician or pharmacist is concerned about an increased risk of misuse, abuse, or diversion.

OPANA ER is an extended-release oral formulation of Oxymorphone indicated for the management of moderate to severe pain when a continuous, around-the-clock opioid analgesic is needed for an extended period of time.

OPANA ER is NOT intended for use as a prn analgesic.

OPANA ER TABLETS are to be swallowed whole and are not to be broken, chewed, dissolved, or crushed. Taking broken, chewed, dissolved, or crushed OPANA ER TABLETS leads to rapid release and absorption of a potentially fatal dose of Oxymorphone.

Patients must not consume alcoholic beverages, or prescription or non-prescription medications containing alcohol, while on OPANA ER therapy. The co-ingestion of alcohol with OPANA ER may result in increased plasma levels and a potentially fatal overdose of Oxymorphone.

OPANA ER is not indicated for pain in the immediate post-operative period (12-24 hours following surgery), or if pain is mild or not expected to persist for an extended period of time.

OPANA ER is contraindicated in patients with a known hypersensitivity to Oxymorphone hydrochloride, morphine analogs such as codeine, or any of the other ingredients of OPANA ER; in patients with moderate or severe hepatic impairment or in any situation where opioids are contraindicated.

Respiratory depression is the chief hazard of OPANA ER, particularly in elderly or debilitated patients.

The most common adverse drug reactions (greater than or equal to 10%) in all clinical trials for OPANA ER were nausea, constipation, dizziness (excluding vertigo), vomiting, pruritus, somnolence, headache, increased sweating, and sedation.
