                                      ---
          GROSS MARGIN EXPANDED TO 53 PERCENT OF NET SALES IN QUARTER

SPRING VALLEY, NEW YORK, JULY 24, 2003 -- Pharmaceutical Resources, Inc.
(NYSE:PRX) today reported that total revenues increased 14 percent to $115.9
million for the second quarter ended June 29, 2003. For the quarter, the Company
achieved net income of $23.1 million and diluted earnings per share of $.68.
Excluding a one-time charge associated with a retirement agreement, net income
rose 24 percent to $25.3 million and diluted earnings per share increased 19
percent to $.74. This is compared with revenues of $101.8 million, net income of
$20.4 million and diluted earnings per share of $.62 for the same period a year
ago.

"The combination of our strong base business and a steady flow of new products
is continuing to drive our success," said Scott Tarriff, president and chief
executive officer of PRX's Par Pharmaceutical subsidiary. "The quarter benefited
from higher than anticipated sales of megestrol oral suspension, fluoxetine and
omeprazole as well as the introduction of three new products. This dynamic
combination enabled PRX to exceed consensus earnings estimates for the second
quarter."

In the second quarter, double-digit sales growth was again driven by the
Company's core products, or base business, which increased 29 percent to $61.3
million. The strong performance of the Company's base business resulted, in
part, from the second-quarter introductions of torsemide, the generic version of
Demadex(R), and minocycline, the generic form of Minocin(R). Base business
growth was also powered by several successful product launches in 2002,
including tizanidine, the generic version of Zanaflex(R).

Omeprazole, the generic version of Prilosec(R), also contributed significantly
to revenue growth in the second quarter, adding $7.1 million of royalty revenue.
In the fourth quarter of 2002, PRX began receiving royalty payments as a result
of KUDCo's launch of omeprazole. In the second quarter, megestrol oral
suspension, the generic form of Megace(R), achieved sales of $22.0 million while
sales of fluoxetine, the generic version of Prozac(R), totaled $24.6 million.
Although megestrol and fluoxetine continued to perform well, the robust sales
growth throughout PRX's base business and the launch of omeprazole effectively
reduced the Company's reliance on each of these key products.





For the second quarter, megestrol and fluoxetine represented approximately 40
percent of PRX's total revenues compared with 53 percent for the same period a
year ago. During the second quarter, PRX also began shipping generic paroxetine
hydrochloride immediate release tablets in the Commonwealth of Puerto Rico.
PRX's paroxetine hydrochloride tablets are substitutable for Paxil(R) and are
licensed from GlaxoSmithKline.

PRX's earnings growth in the second quarter benefited from continued improvement
in the Company's gross margin. Driven by royalty revenue from sales of
omeprazole, PRX's gross margin improved to 53 percent compared to 46 percent in
the second quarter of 2002. Investment in research and development (R&D)
increased 14 percent to $4.7 million in this year's second quarter.

"Sustaining growth for years to come remains our primary objective at PRX," said
Mr. Tarriff. "The key will be maintaining the strength and productivity of our
new product pipeline. This year, PRX will invest a record amount in research and
development. We now have 25 Abbreviated New Drug Applications (ANDA) awaiting
approval at the U.S. Food and Drug Administration (FDA). Going forward, it is
our goal to continue to invest heavily in R&D while maintaining our commitment
to earnings growth. We will continue to complement our internal R&D efforts by
aggressively pursuing promising business development opportunities like our
recently announced licensing agreement with Paddock Laboratories for
testosterone 1% gel (Androgel(R))."

Among the 25 drugs currently awaiting approval by the FDA, PRX believes that
several may represent first-to-file opportunities entitling the Company, or its
strategic partner, up to 180 days of marketing exclusivity or co-exclusivity.
These products include: olanzapine 20 mg (Zyprexa(R)); latanoprost (Xalatan(R));
ribavirin (Rebetol(R)); tramadol with acetaminophen (Ultracet(R)); and
testosterone 1% gel (Androgel(R)). It should be noted that it is difficult to
know with certainty that an ANDA filing has exclusivity, or shared exclusivity,
until final approval is received from the FDA.

For the six months ended June 30, 2003, total revenues advanced 22 percent to
$222.3 million, compared with $182.3 million for the same period in 2002.
Reported net income of $45.6 million and diluted earnings per share of $1.34
increased from $41.1 million and $1.25 per share in the first six months of
2002. The 2002 period includes a net benefit resulting from settlements with
Bristol-Myers Squibb and International Specialty Products. Excluding this net
benefit and the aforementioned one-time retirement charge, net income rose 25
percent to $47.8 million and diluted earnings per share increased 22 percent to
$1.41 for the first six months of 2003. This is compared with net income of
$38.2 million and diluted earnings per share of $1.16 for the first six months
of 2002, after excluding the net benefit of the two prior-year settlements.

For the first six months of 2003, PRX's gross margin improved to 52 percent
compared to 47 percent in the same period a year ago. This improvement reflected
sales of new, higher-value products, including royalty revenue resulting from
sales of omeprazole. Investment in R&D increased 60 percent to $11.1 million for
the first six months of this year. The substantial increase in R&D underscores
PRX's commitment to identify, formulate and develop a continuing stream of
promising new products.





In other product developments since the end of the first quarter of 2003:

   o  PRX's partner, Three Rivers Pharmaceuticals, was granted summary judgment
      of non-infringement regarding its ribavirin product by the United States
      District Court for the Central District of California. This decision
      resolves the remaining patent barriers to FDA approval of the ANDA filed
      by Three Rivers. PRX has exclusive marketing rights for the Three Rivers'
      ribavirin product. Ribavirin is marketed by Schering-Plough under the
      brand name Rebetol(R);
   o  PRX was issued two additional patents relating to megestrol oral
      suspension. The patents collectively contain more than 70 additional
      claims related to PRX's novel formulation of megestrol oral suspension.
      PRX now holds four patents relating to this product. Based on these new
      patents the Company filed suit against Roxane Labs claiming patent
      infringement;
   o  PRX entered into a licensing agreement with developer Paddock Laboratories
      to market its testosterone gel 1%, the generic version of Androgel(R). The
      ANDA was recently accepted by the FDA and is believed to be the first ANDA
      filed with a paragraph IV notification, potentially providing for 180 days
      of exclusivity;
   o  PRX commenced shipment of torsemide tablets, the generic form of Roche's
      Demadex(R). PRX developed and filed an ANDA for torsemide in conjunction
      with Kali Laboratories and entered into a licensing agreement with Roche
      to allow PRX to market torsemide; and
   o  PRX began shipment, in the Commonwealth of Puerto Rico, of generic
      paroxetine hydrochloride immediate release tablets that are substitutable
      for Paxil(R) and are licensed and supplied from GlaxoSmithKline. PRX will
      be entitled to distribute the same product in the U.S. market once another
      generic paroxetine hydrochloride immediate release tablet fully
      substitutable for Paxil(R) becomes available there.

Pharmaceutical Resources, Inc., a holding company, develops, manufactures, and
