APP PHARMACEUTICALS REPORTS 2008 FIRST

QUARTER NET REVENUES OF $148 MILLION, GROSS

PROFIT OF $70 MILLION

• Reports 11% Increase in Income from Operations Before Interest Expense to $32.5 Million

• Receives Four New Product Approvals from FDA in the 2008 First Quarter

SCHAUMBURG, Illinois–May 8, 2008 – APP Pharmaceuticals, Inc. (Nasdaq:APPX), a leading manufacturer of multi-source and branded injectable pharmaceutical products, today reported financial results for the first quarter ended March 31, 2008. As a result of the separation of Abraxis BioScience from APP Pharmaceuticals, APP’s business is reported, for all periods presented, on a continuing operations basis and Abraxis BioScience’s business is reported in discontinued operations.

“The foundation we have established as a company has demonstrated our strength and ability to respond effectively to opportunities in the marketplace,” said Tom Silberg, APP Pharmaceuticals’ recently named president and chief executive officer. “We leveraged our flexible manufacturing capabilities to rapidly increase the supply of heparin toward the end of the first quarter and avert a potential market shortage for this critical care product. We expect that our strong core business, combined with recently introduced and anticipated new product launches, should contribute to continued revenue and earnings growth throughout the balance of the year.”

For the 2008 first quarter, net revenues increased 6 percent to $148.1 million, compared with $140.3 million in the first quarter of 2007. Gross profit was $70.1 million, or 47 percent of net revenues for the first quarter of 2008, compared with $65.4 million, or 47 percent of net revenues, in the first quarter of 2007. Excluding $4.1 million for amortization of purchased products, gross profit was $74.2 million, or 50 percent of net revenues compared with $69.5 million or 50 percent of net revenues.

2008 First Quarter Financial Results

Total operating expenses were $37.6 million, compared with $36.2 million in the 2007 first quarter. Research and development expenses were $12.3 million compared with $10.0 million in last year’s first quarter. SG&A expenses were $21.0 million, or 14 percent of net revenues, compared with $22.1 million, or 16 percent of net revenues, in the prior year first quarter.

Income from operations before interest expense for the 2008 first quarter increased by 11% to $32.5 million compared with $29.2 million in the 2007 first quarter. Net interest expense was $15.7 million compared with $3.6 million in the last year’s first quarter, primarily reflecting the increase in borrowing following the separation that was completed in November 2007.

As a result of increased net interest expense, net income was $9.2 million, or $0.06 per diluted share, versus first quarter 2007 net income of $11.1 million, or $0.07 per diluted share, which includes a loss from discontinued operations of $2.5 million, or $0.02 per share. The company reported first quarter adjusted net income from continuing operations of $22.0 million, or $0.14 per diluted share, which in each case excludes Puerto Rico facility pre-launch costs, amortization expense, non-cash stock compensation expense and other items (see table at the end of this release).

In the first quarter of 2008, APP received final FDA approval on four products and launched the following Polymixin B Sulfate, Caffeine Citrate Oral Solution, and Irinotecan Hydrochloride. Additionally, the company launched Cefepime Hydrochloride.

APP currently has more than 60 product candidates in various stages of development, including 27 ANDAs pending with the FDA, representing approximately $5 billion in 2007 annualized branded sales.

GAAP to Adjusted Earnings from Continuing Operations Reconciliation

(unaudited, in thousands, except per share amounts)

Adjusted income from continuing operations and adjusted income from continuing operations per diluted share are defined as income from continuing operations and diluted earnings from continuing operations per share, respectively, in each case excluding the impact of, non-cash stock compensation expense, separation related costs, amortization of acquired intangible assets and merger related intangibles and Puerto Rico pre-launch costs. We believe that our presentation of non-GAAP financial measures provides useful supplementary information to investors in understanding our underlying operating performance and facilitates additional analysis by investors. We also use non-GAAP financial measures internally for operating, budgeting and financial planning purposes. The non-GAAP financial measures are in addition to, and not a substitute for or superior to, measures of financial performance calculated in accordance with GAAP. A reconciliation of GAAP income from continuing operations to adjusted income from continuing operations for the three months ended March 31, 2008 is below:

Reconciliation of Income from Continuing Operations to Adjusted EBITDA

Three Months Ended March 31, 2008

(unaudited, in thousands)

We define Adjusted EBITDA from continuing operations as income from continuing operations, excluding the impact of depreciation and amortization, interest expense net of interest income and other income, income tax expense, non-cash stock-based compensation expense, separation related costs and pre-launch costs associated with Puerto Rico manufacturing facility. We use adjusted EBITDA from continuing operations to provide meaningful supplemental information to investors in understanding the underlying operating performance of the business and facilitate additional analysis by investors. We believe that Adjusted EBITDA from continuing operations can assist management and investors in assessing the financial operating performance and underlying strength of our core business. Adjusted EBITDA from continuing operations is not a recognized term under GAAP and should not be considered in isolation of, or as a substitute for, the information prepared and presented in accordance with GAAP. Because not all companies calculate Adjusted EBITDA from continuing operations identically, our definition of Adjusted EBITDA from continuing operations may not be comparable to similarly titled measures of other companies.

	March, 31 2008
Income from continuing operations net of income tax	$	9,157
Depreciation		4,492
Amortization		7,994
Interest expense, net of interest income		16,245
Provision for income taxes from continuing operations		7,571
