Sales and production of this drug have increased significantly in recent years, as have diversion and illicit use. Hydrocodone is commonly available in tablet, capsule and syrup form.

As a narcotic, hydrocodone relieves pain by binding to opioid receptors in the brain and spinal cord. It may be taken with or without food, but should never be combined with alcohol. It may interact with monoamine oxidase inhibitors, as well as other drugs that cause drowsiness. It is in FDA pregnancy category C: its effect on an unborn embryo or fetus is not clearly known and pregnant women should consult their physicians before taking it. Common side effects include dizziness, lightheadedness, nausea, drowsiness, euphoria, vomiting, and constipation. Some less common side effects are allergic reaction, blood disorders, changes in mood, mental fogginess, anxiety, lethargy, difficulty urinating, spasm of the ureter, irregular or depressed respiration and rash.

Hydrocodone can be habit-forming, and can lead to physical and psychological addiction. In the U.S., pure hydrocodone and forms containing more than 15 mg per dosage unit are called hydrocodone compounds and are considered Schedule II drugs. Those containing less than 15 mg per dosage unit are Schedule III drugs. Hydrocodone is typically found in combination with other drugs such as paracetamol (acetaminophen), aspirin, ibuprofen and homatropine methylbromide. In the UK it is listed as a Class A drug under the Misuse of Drugs Act 1971.

The presence of acetaminophen in hydrocodone-containing products deters many drug users from taking excessive amounts. However, some users will get around this by extracting a portion of the acetaminophen using hot/cold water, taking advantage of the water-soluble element of the drug. It is not uncommon for addicts to have liver problems from taking excessive amounts of acetaminophen over a long period of time--taking 10–15 grams of acetaminophen in a period of 24 hours typically results in severe hepatotoxicity. It is this factor that leads many addicts to use only single entity opiates such as OxyContin.

Symptoms of hydrocodone overdosage include respiratory depression, extreme somnolence, coma, stupor, cold and/or clammy skin, sometimes bradycardia, and hypotension. A severe overdose may involve circulatory collapse, cardiac arrest and/or death.

Andrx Corporation Reports 2005 Third Quarter Results
From Business Wire, 11/7/05

FORT LAUDERDALE, Fla. -- Andrx Corporation (Nasdaq:ADRX) (Andrx or the Company) today announced its financial results for the three and nine months ended September 30, 2005 (the 2005 Quarter and the 2005 Period, respectively), which are discussed more extensively in Andrx's Form 10-Q being filed today with the U.S. Securities and Exchange Commission (SEC). Andrx's Form 10-Q is available on the Company's website at http://www.andrx.com (Investor Relations/SEC filings).

Andrx Chief Executive Officer, Thomas P. Rice, said: "We are now realizing the increasing benefit from the disposition of our brand business, which occurred earlier this year. Our distribution business experienced a solid operating quarter within a very competitive generic environment, which included the launch of generic Allegra(R). We believe future financial results from our distribution operations will benefit from new generic launches of significant brand products losing patent protection in 2006 and 2007. However, this growth may be tempered by continuing price erosion within the industry."

"During the 2005 third quarter, the FDA placed us in Official Action Indicated status relating to the FDA's inspection of our Davie, Florida manufacturing facility and the FDA's issuance of a Form 483 List of Inspectional Observations. The effect of this designation is that while the FDA reviews our responses to the inspectional observations and considers whether or not to take any enforcement action against us, approvals of our submitted ANDAs are being withheld. However, the Company continues to submit new ANDAs and the FDA continues to review our applications. We believe we have provided complete responses to the May 2005 inspectional observations and anticipate a meeting with the FDA in November to discuss our responses."

"We have expanded our facilities, upgraded our senior management team in science and technology, quality assurance, manufacturing operations, and business development, and improved our manufacturing and quality systems. The benefit of improving our manufacturing processes is evidenced by, among other things, the year-over-year decrease in our production-related write-offs."

Mr. Rice added: "With respect to Biaxin(R) XL, in September a hearing took place regarding Abbott Laboratories, Inc.'s motion for preliminary injunction. We are awaiting the court's decision."

"We continue to invest in business development efforts to expand our generic pipeline, and expect to continue to realize the synergies between our distribution and generic businesses for both our internally developed products and generic business development opportunities. We are in advanced discussions, and anticipate closing before the end of the year, transactions to access up to 25 ANDAs from international companies and domestic companies with off-shore affiliations. This quarter we also established Andrx Therapeutics, our contract services segment to be led by Steve Glover, Senior Vice President, which is pursuing the development and manufacturing of pharmaceutical products for other pharmaceutical companies, including combination products and controlled-release formulations utilizing our patented technologies and formulation capabilities."

Highlights for Third Quarter 2005

In the 2005 Quarter, distributed products revenues increased by 3.5% to $163.6 million from the three months ended September 30, 2004 (2004 Quarter), due to new generic product introductions since the 2004 Quarter, partially offset by the overall price declines common to generic products. Distributed products revenues in the 2005 Quarter included the reversal of a $2.0 million reserve related to Able Laboratories, Inc.'s recall of its products, as our return experience since the recall indicates our exposure is less than originally anticipated. On a quarterly sequential basis, revenue from distributed products decreased by 3.1% from $168.8 million for the 2005 second quarter. Affecting the comparison to the 2005 second quarter, among other things, is our previously announced discontinuation of the distribution of certain brand products, which generated $0.9 million in sales in the 2005 Quarter and $6.1 million in the 2005 second quarter. In the 2005 Quarter, gross margin on distributed products was 20.3% compared to a gross margin of 17.9% for the 2004 Quarter. The improvement in the gross margin was primarily attributable to the impact of higher margins related to a new product introduction, as well as the reversal of the reserve related to Able's recall.

After the disposition of our brand business in March 2005 through a sales and licensing transaction with First Horizon, Andrx products revenues exclude revenues from Altoprev(R) and Fortamet(R). Our participation in the performance of these brand products is now included in licensing, royalties and other revenues. Sales of these products were $16.1 million in the 2004 Quarter. Andrx product sales for the 2005 Quarter include sales of controlled-release, immediate-release and niche generic products, and other products, which include our Entex and Anexsia product lines previously reflected in Andrx brand product revenues. Excluding net sales of Altoprev and Fortamet for the 2004 Quarter, Andrx products revenues decreased by $18.5 million to $71.5 million, compared to $90.0 million in the 2004 Quarter. The decrease is primarily due to decreases from our generic versions of Glucotrol XL(R), supplied by Pfizer, OTC Claritin-D(R) 24, K-Dur(R) and Glucophage(R). Andrx did not launch any products during the 2005 Quarter. On a quarterly sequential basis, reported revenues from Andrx products decreased by 8.8% from $78.3 million primarily due to decreases from our generic versions of Glucotrol XL, supplied by Pfizer, Glucophage, OTC Claritin-D 24 and other products previously reflected as Andrx brand product revenues. Excluding net sales of Altoprev and Fortamet, Andrx products generated $23.9 million of gross profit with a gross margin of 33.4% in the 2005 Quarter, compared to $34.1 million of gross profit with a gross margin of 37.9% in the 2004 Quarter. The $10.2 million decrease in gross profit resulted primarily from reductions in revenues, partially offset by a $2.4 million reduction in cost of goods sold as a result of Pfizer's failure to deliver generic Glucotrol XL 2.5mg in accordance with our supply agreement. In the 2005 Quarter, we recorded charges directly to cost of goods sold of $4.1 million in write-offs of pre-launch inventories, mainly due to $3.4 million in write-offs of our generic version of Biaxin XL in connection with validation and the commencement of commercial production activities.

In the 2005 Quarter, licensing, royalties and other revenues increased to $21.9 million, compared to $8.1 million in the 2004 Quarter primarily due to revenues from First Horizon related to Andrx's former brand products, which commenced in April 2005. In the 2005 Quarter, based on the results of an external review, we recorded $3.9 million of revenues on the reversal of sales allowances previously recorded related to our agreements for generic versions of Wellbutrin SR(R) 150mg and Zyban(R). In addition, licensing, royalties and other revenues in the 2005 Quarter include contract R&D services revenue rendered to Takeda Chemical Industries, Ltd. of $1.3 million. Licensing, royalties and other revenues in the 2004 Quarter primarily consisted of royalties on Teva's sale of Impax's generic versions of Wellbutrin SR 150mg and Zyban, and KUDCo's sale of generic Prilosec(R). On a quarterly sequential basis, licensing, royalties and other revenues increased by $8.2 million from $13.7 million.

Selling, general and administrative expenses (SG&A) were $46.2 million for the 2005 Quarter, or 18.0% of total revenues, compared to $54.2 million, or 19.9% of total revenues for the 2004 Quarter. Excluding the brand business segment, SG&A expenses were $44.7 million for the 2005 Quarter, compared to $32.5 million for the 2004 Quarter. SG&A for the 2005 Quarter includes $9.3 million in charges associated with the separation agreement with our former Executive Vice President, General Counsel and Secretary, $7.0 million of which was a non-cash charge related to his 2001 employment agreement which, upon his termination, modified the exercise period of his previously issued stock options. This non-cash charge of $7.0 million was based on the exercise price of stock options issued prior to the 2001 agreement, compared to the price of Andrx stock of $64.92 as of the date of the modification (date of employment agreement). On a quarterly sequential basis, SG&A expenses excluding the brand business segment increased by $8.6 million from $36.1 million.

Research and development expenses (R&D) were $10.3 million in the 2005 Quarter, compared to $10.0 million in the 2004 Quarter. On a quarterly sequential basis, R&D decreased from $11.7 million.

On September 23, 2005, we gave notice that we were terminating our 2002 credit facility, which cost approximately $1.4 million in annual fees to maintain. The termination was effective October 19, 2005. Accordingly, in the 2005 Quarter, we wrote-off unamortized debt issuance costs of $1.2 million as a non-cash charge.

For the 2005 Quarter, we recorded a provision for income taxes of 35%. The 2005 Quarter included the benefit of the resolution of uncertain tax positions. We continue to expect our effective tax rate generally to be 38% for the remainder of 2005 excluding any adjustments made to our tax liabilities as a result of the completion of the IRS' audits of our 1999 through 2002 tax returns.

As of September 30, 2005, we had $401 million in cash, cash equivalents and investments available for sale, and $486 million of working capital. Deferred revenues were $102 million, primarily due to cash received from our transactions with Takeda and First Horizon.

Capital expenditures were $8.5 million in the 2005 Quarter and $21.6 million in the 2005 Period, compared to $73.2 million for the 2004 Period.
