BENTLEY PHARMACEUTICALS, INC. REPORTS RECORD FIRST QUARTER RESULTS

- - Total Revenues  Increase 63% (37% at constant exchange rates) to $15.0 Million
- - Net Income  grows  dramatically  - up 11 times to $1.5  Million,  or $0.08 per
Diluted Share

EXETER,  NH,  APRIL 29, 2003 -- Bentley  Pharmaceuticals,  Inc.  (AMEX:  BNT), a
technology-based  specialty  pharmaceutical  and drug  delivery  company  with a
growing  branded and generic  product  line in Europe,  today  announced  record
financial results for the three months ended March 31, 2003.

Total  revenues  for the quarter  grew 63% (37% at constant  exchange  rates) to
$15.0 million compared to $9.2 million in the same period last year. Net product
sales increased 57% (31% at constant exchange rates) to $14.2 million, from $9.1
million in last year's first quarter.  First quarter licensing and collaboration
revenues  increased  significantly  to $0.8  million  versus $0.1 million in the
first quarter of last year.

First  quarter  operating  income more than  tripled to $2.7  million  from $0.8
million in the  comparable  2002 quarter.  Net income for the 2003 first quarter
increased to $1.5 million, or $0.08 per diluted share,  compared to $135,000, or
$0.01 per diluted  share,  in last year's first  quarter.  Gross  margins on net
product  sales in the first quarter of 2003 were 57% compared to 58% in the same
period of the prior year.

Research and  development  expenses  increased by 33% from $764,000 in the first
quarter of 2002 to $1.0 million in the first quarter of 2003.  The  expenditures
reflect our focus on projects  that are necessary for expansion of our portfolio
of  marketed   products  and  clinical   trials   involving  our  drug  delivery
technologies.





With respect to licensing and  collaboration  revenues,  Bentley has  recognized
royalty revenues based on estimated sell-through of pharmaceutical products, and
has deferred  recognition of royalty revenues  associated with the initial sales
made  to  wholesalers   and  pharmacies  to  fill  the   distribution   channel.
Pharmaceutical  products  are  typically  sold  with  limited  shelf  lives  and
wholesalers and pharmacies  have the right to return unsold or expired  product.
The company's  policy,  therefore,  is to recognize royalty revenues based on an
estimate of the  prescriptions  written by  physicians  and filled by  patients,
until such time that returns from  wholesalers  and pharmacies can be reasonably
estimated.  The company will use available  market  information to determine the
amounts and timing of royalty revenues it recognizes.

James Murphy,  Bentley's  president and chief executive officer commented,  "Our
strong first quarter results reflect  significant growth in sales of our generic
pharmaceuticals in Spain."

Continuing,  Mr. Murphy stated, "We continue to make significant progress - this
quarter,   we  have   achieved   milestones   in  both  our  drug  delivery  and
pharmaceutical product sales businesses. In February, together with our licensee
Auxilium,  we announced the U.S. launch of Testim,  the first product  utilizing
our proprietary CPE-215(TM) technology.  Last week we reported that results from
a recent  study,  published in the April 2003 issue of  Biopharmaceutics  & Drug
Disposition  found that `patients treated with Auxilium's  Testim,  absorbed 30%
more  testosterone  dose for dose than patients  treated with  AndroGel(R),  the
other  commercially  available  testosterone  gel.' In addition,  together  with
Auxilium,  we will be  announcing  later  today the  publishing  of  results  of
additional  clinical data with respect to Testim.  We look forward to giving you
more  information  regarding  this  after it has been  presented  at the  annual
meeting of the American Urological Association (AUA) in Chicago, Illinois."

Mr. Murphy added, "Also during the quarter,  we received  regulatory approval by
the Spanish  Ministry of Health to market the generic  equivalents of well-known
cardiovascular  and  anti-infective   pharmaceuticals   Zestril/Prinivil(R)  and
Augmentin(R)  and are on track to launch  these  products  in Spain  during  the
second half of 2003.  Building on the  strength  of our  business  model and our
proprietary  CPE-215  drug  delivery  technology,  we  continue  to execute  our
strategy of expanding our presence in Spain's  emerging  generic drug market and
leveraging our CPE-215  platform  technology to advance our pipeline and product
portfolio."

Michael D. Price,  Vice President and Chief  Financial  Officer  added,  "We are
delighted with the strong financial results this quarter,  and believe the steps
we have  taken to  develop  our  business  model are now  beginning  to be fully
recognized. Clearly, Testim's product launch is in its early stages, with only 5
weeks of product  marketing  during this quarter.  We look forward to discussing
the  potential  impact that this  product  gives  Bentley  Pharmaceuticals  next
quarter when we will have more data available. That said, early indications give
us confidence  going  forward,  which combined with the growth in sales from our
Spanish operations, position the company well for the full year."

Management will host a conference call to discuss these results today,  Tuesday,
April 29, 2003, at 8:30 a.m.  Eastern Daylight Time. The dial-in number for U.S.
callers is (800)  603-9527;  International  callers should dial (706)  634-0645.

available until May 6, 2003.  Please dial (800)  642-1687,  access code 9851079.
