             Alfuzosin Approved by the Food and Drug Administration
                              in the United States
  Outside of the United States, alfuzosin is marketed under the name Xatral(R)



Sanofi-Synthelabo announced today that its New Drug Application (NDA) for
alfuzosin HCl extended-release tablets has been approved in the United States by
the Food and Drug Administration (FDA).


Alfuzosin is indicated for the treatment of the signs and symptoms of benign
prostatic hyperplasia.

Alfuzosin, a compound from Sanofi-Synthelabo Research, is an alpha(1)-blocker in
a 10 mg once-daily extended-release formulation.

Alfuzosin exhibits selectivity for alpha(1)-adrenergic receptors in the lower
urinary tract. Blockade of these adrenoreceptors can cause smooth muscle in the
bladder neck and prostate to relax, resulting in an improvement in urine flow
and a reduction in symptoms of benign prostatic hyperplasia (BPH).

BPH is a very common disorder, leading to urinary symptoms of varying severity.
The resulting symptoms affect 22% of men aged 50-59 years, but up to 45% of men
aged 70-80 years. These symptoms may have an impact on men's day-to-day
activities and may lead to serious complications such as acute urinary
retention. Clinical efficacy data for alfuzosin from placebo-controlled trials
have demonstrated efficacy compared to placebo in urinary flow improvement and
in improvement in urinary symptoms without the need for dose titration.

In the clinical trials, the most common side effects occurring more frequently
than placebo were dizziness, upper respiratory tract infection, headache and
fatigue.

Alfuzosin should not be used in patients with moderate to severe hepatic
insufficiency. Alfuzosin should not be co-administrated with potent inhibitors
of the cytochrome P3A4. As with other alpha-blockers, some patients may
experience postural hypotension or syncope. Alfuzosin should not be used in
combination with other alpha-blockers. If symptoms of angina pectoris should
appear or worsen, the use of alfuzosin should be discontinued.

With 15 years of clinical experience, which translates into approximately 1.35
billion days of treatment (3.7 million patient years), alfuzosin is marketed in
more than 80 countries throughout Europe, Latin America, Africa and Asia.
Outside of the United States, the once-daily formulation (Xatral(R) OD) is
registered in 70 countries worldwide; it is currently marketed in 14 countries
in Europe and in more than 35 other countries.

The launch of alfuzosin HCl extended-release tablets in the United States will
occur in the second half of 2003.

Sales of alfuzosin reached 182 million euros in 2002 and 49 million euros in the
first quarter of 2003.

Sanofi-Synthelabo is a major global research-based pharmaceutical group with
32,500 employees in more than 100 countries. The company is headquartered in
Paris and listed in Paris (Euronext : SAN) and in New York (NYSE : SNY). With
