    IVAX Reports Increased Revenues and Net Income for 2nd Quarter of 2003;
 2Q2003 Net Revenues Up 22% to $343 Million, Net Income Up 30% to $41.3 Million

    MIAMI--(BUSINESS WIRE)--July 30, 2003--IVAX Corporation (AMEX:IVX)
(LSE:IVX.L) reported second quarter 2003 net revenues of $343.0
million, a 22% increase over net revenues of $280.4 million in the
second quarter of 2002; net income of $41.3 million, a 30% increase
over net income of $31.7 million in the second quarter of 2002; and
earnings per share of $.21 (including $.11 per share from discontinued
operations), an increase of 31% over earnings per share of $.16 in the
second quarter of 2002. For the first two quarters of 2003, net
revenues were $660.7 million, net income, $70.3 million, or $.36 per
share; compared to net revenues of $552.6 million, net income, $55.2
million, or $.28 per share for the first two quarters of 2002,
increases of 20%, 27% and 29% respectively.
    Commenting on the second quarter's results, Neil Flanzraich, vice
chairman and president of IVAX Corporation said, "Driving our second
quarter results were increases in revenues from our North American,
European and Latin American operations. In Europe and North America,
revenues increased by 26%. Latin American revenues showed a 4% growth
over revenues in the second quarter 2002 and a 19% increase over
revenues from the first quarter 2003. The results of the first and
second quarters of 2003 indicate continuing, robust growth in our
business."
    During the second quarter, IVAX received the first of a series of
payments from B. Braun Melsungen AG, under a number of agreements, for
certain patent and product rights and for settlement of litigation.
The net present value of these payments is $22.2 million after
expenses, fees, and taxes, or $.11 per share. In accordance with
current accounting rules, all of this income has been accounted for in
this quarter as earnings from discontinued operations because the
agreements originated from a relationship that began with the sale of
a former IVAX business.
    "Our anticipation of these B. Braun payments," Mr. Flanzraich
said, "allowed IVAX to accelerate spending to build our business. Of
course, these expenditures decreased income from continuing operations
in the quarter but we believe that they will increase future revenues
and profits. We increased spending on IVAX' recently acquired facility
to manufacture active pharmaceutical ingredients (API's) in Puerto
Rico to bring it up to IVAX' standards, as well as on our R&D program,
and our marketing and sales efforts for branded products in the United
States and France. We also incurred a one-time expense for a lump-sum
retirement payment to Isaac Kaye, the former Chairman of IVAX
Pharmaceuticals, UK, who retired in June 2003."
    IVAX expects to benefit during the rest of the year and into 2004
from:

            --  Increased capacity at IVAX' finished product and API
                facilities will help meet the strong, growing demand
                for its products. By supplying API's from its own
                plants, it will also lower cost of goods and increase
                operating margins.

            --  IVAX' recently announced transaction with 3M gives
                IVAX additional, profitable, branded asthma products
                and additional, experienced marketing and sales
                infrastructure in nine European countries. This will
                rapidly increase IVAX' presence in Europe, and give it
                a broader platform from which to sell other products.
                IVAX expects the products and infrastructure it
                acquired to increase its sales and profitability in
                Europe; and to increase efficiencies and provide
                synergies in the utilization of infrastructures in the
                U.K. and France, to further increase profitability.

            --  IVAX expects the European approval and launch of
                paclitaxel for its primary cancer indications.
                Currently, Bristol Meyers is the sole provider
                of this product in Europe and its prices there are
                considerably higher than in the U.S.

            --  IVAX' strong business in Latin America should benefit
                from improving economic conditions as well as from the
                launches of new products and greater operating
                efficiencies.

            --  In the U.S., IVAX' asthma drug, QVAR(R), is being
                marketed as the ideal product for treating lower
                airway disease and continues to gain market share.
                Additionally, IVAX anticipates the approval of its NDA
                on Volare(TM), a chlorofluorocarbon-free formulation
                of albuterol in a metered-dose inhaler, used
                as a "rescue" medication for asthma.

            --  So many of IVAX' proprietary drug candidates are
                progressing well in advanced clinical development that
                IVAX feels the need to focus, and has accordingly
                undertaken to out-license some of these products. Such
                arrangements may result in upfront and milestone
                payments, even before the products reach market, and
                later in royalty payments. These arrangements would
                also have the effect of reducing IVAX' R&D costs. IVAX
                also expects to receive additional payments from its
                existing collaborations. The present value of this
                pipeline is considerable and growing, and will in time
                be reflected in the price of IVAX' shares.

            --  IVAX expects to file several additional generic
                applications with the FDA before the end of the year,
                adding to a pipeline that currently has 39 generic
                applications pending. Furthermore, IVAX anticipates
                significant additions to this pipeline from previously
                announced and new partnerships with other companies.
                IVAX anticipates launches of generic versions of
                important brand products during the balance of 2003
                and 2004. These include products with great potential
                for IVAX, but may depend on success with on-going
                litigation.

    "We look forward to reporting on the impact of these developments
and the growing demand for our products on future sales and earnings,"
concluded Mr. Flanzraich.

that cannot be predicted or quantified and, consequentially, actual
results may differ materially from those expressed or implied by such
forward-looking statements. Such risks and uncertainties include,
among others, that increased expenditures may not increase our future
revenues and profits; that production from API Industries may not
increase and may not keep pace with growth in demand for our generics
or provide a lower cost of goods sold or increased operating margins;
that our increased presence in Europe may not increase our sales and
profitability or give us a broader platform for our products; that
efficiency and synergies in the U.K. and France may not increase our
profitability; that economic conditions in Latin America may not
improve; that IVAX may not enter into new product collaboration and
license agreements, receive upfront, milestone or royalty payments
from such agreements, or receive additional payments from existing
agreements; that IVAX may not receive approval for, or launch, its
paclitaxel product in Europe; that IVAX may not receive approval for
Volare(TM); that demand for our products may not increase; that
political and economic instability in some countries in which we
conduct our business, particularly Latin American countries, may
adversely affect the revenue our foreign operations generate; that
IVAX has in the past and may in the future experience difficulties in
obtaining raw materials necessary for the production of IVAX' products
on commercially reasonable terms or at all; that clinical trials and
studies for products and compounds under development may not be
commenced, may take longer than anticipated, may fail, may not achieve
the expected results or effectiveness and may not generate the data
that would support the approval or marketing of these products for the
indications being studied or for other indications; that the compounds
and products in IVAX' research pipeline will not be successfully
developed, will not receive regulatory approval, will not be
successfully commercialized or will not be reflected in the price of
our shares; the uncertainties related to the timing or outcome of
product development; that IVAX may not file new ANDAs during 2003 or
add to our pipeline from our R&D or collaborations. In addition to the
risk factors set forth above, IVAX' forward looking statements may
also be adversely affected by general market factors, competitive
product development, product availability, current and future branded
and generic competition for the company's products, federal and state
regulations and legislation, the regulatory process for new products
and indications, manufacturing issues that may arise, trade buying
patterns, exchange rate fluctuations, patent positions and the timing
