        CollaGenex Pharmaceuticals Reports Revenues and Earnings for the
        ----------------------------------------------------------------
                             First Quarter of 2004
                             ---------------------

               Net Loss Allocable to Common Stockholders of $0.03
         per Share Reflects $0.14 per Share One-time Charge Relating to
                               Mutual Settlement


Newtown, PA, April 27, 2004 - CollaGenex  Pharmaceuticals,  Inc. (Nasdaq:  CGPI)
today  reported  financial  results for the first  quarter ended March 31, 2004.
Total revenues  increased 10% to $13.4 million  compared to $12.2 million in the
first quarter of 2003. Net product sales were $13.3 million in the first quarter
of 2004, a 17% increase over net product sales of $11.4 million  recorded in the
first quarter of 2003.

     During  the first  quarter  of 2004,  the  Company  reported  a net loss of
$34,000 compared to net income of $1.2 million during the first quarter of 2003.
Net loss  allocable  to common  stockholders  for the first  quarter of 2004 was
$434,000,  or $0.03 per basic  and  diluted  share,  compared  to net  income of
$828,000,  or $0.07 per basic and diluted  share,  in the first quarter of 2003.
The net loss in the first quarter of 2004 included a charge of $2.0 million,  or
$0.14 per  basic  and  diluted  share,  for a  one-time  payment  to  URL/Mutual
Pharmaceuticals  Company,  Inc.  ("Mutual") in connection with the settlement of
all outstanding  litigation between Mutual and CollaGenex  announced on April 8,
2004. CollaGenex is entitled to deduct costs incurred in defense of its patents,
including  this  payment,  from  current and future  royalties  due to the State
University of New York on sales of Periostat(R).

     "Our first quarter 2004 net product sales and earnings  before the one-time
Mutual  settlement  charge were  significantly  higher than the first quarter of
2003," said Colin W. Stewart,




president  and chief  executive  officer of  CollaGenex.  "The most  significant
development  in the quarter was the  successful  resolution  of the  outstanding
litigation between CollaGenex and Mutual Pharmaceuticals. This agreement removes
the risk of a possible adverse outcome and allows us to move forward and execute
our strategic plan in both the dental and  dermatology  sectors of our business.
In addition, we can now move forward aggressively to invest in our R&D portfolio
and the long term growth of our company."

     During the first  quarter  of 2004,  the  Company  announced  the  positive
results of a 134-patient Phase III clinical trial that evaluated the efficacy of
Periostat to treat rosacea, a disease  characterized by inflammatory lesions and
erythema (skin redness) affecting the nose, cheeks and forehead.  The clinically
and  statistically  significant  results  showed that the  patients who had been
administered  Periostat during the 16-week course of the trial improved markedly
better than the patients on placebo.  The data and  information  generated  from
this  trial  form the basis for  designing  two  Phase  III  trials to  evaluate
Periostat MR in the  treatment of rosacea.  These  studies are expected to begin
during the second quarter of 2004.

     CollaGenex  recently  initiated patient screening and enrollment of a Phase
III clinical study to evaluate the efficacy of Periostat MR for the treatment of
adult periodontitis.  The periodontitis study will enroll more than 200 patients
and provides  for nine months of dosing with either  Periostat MR or placebo and
will analyze the changes in clinical  attachment  level and  periodontal  pocket
depth.  The initiation of this study is an important  milestone in  CollaGenex's
efforts to improve patient compliance with its once-daily formulation and extend
the patent life of Periostat.

     CollaGenex also recently  announced the realignment of its sales force into
two  dedicated  units,  one focused on dentistry  and the other on  dermatology.
Prior  to  the   reorganization,   virtually  all  of  CollaGenex's   115-person
pharmaceutical  sales force called on both dentists and dermatologists to market
the Company's  products.  After the  restructuring,  CollaGenex will be covering
virtually the same number of doctors with a 56-person dental sales force calling
on a highly targeted group of 10,000 high  prescribing  dentists and a 33-person
dermatology sales force calling on the 5,600  dermatologists who are the highest
prescribers of acne, rosacea and dermatitis products.




     "The  realignment  of our sales  organization  into  dedicated  dental  and
dermatology sales forces will focus our representatives'  time on the top decile
prescribers in each  therapeutic  area.  This should  increase our yield on each
call  and  maintain  sales  growth  with  fewer  representatives.  It will  also
significantly  reduce  our  selling,  general  and  administrative  cost  base,"
commented Nancy C. Broadbent, CollaGenex's chief financial officer. "The savings
from this  reorganization,  coupled with lower expected legal expenses following
our  settlement  with  Mutual,  will  reduce  our  2004  selling,   general  and
administrative   expenses,   excluding  the  one-time   charge  for  the  Mutual
settlement, to approximately $30 million compared to $33.7 million during 2003."

     "We  believe  that our sales force  realignment  will also  facilitate  the
addition of in-licensed and/or co-promoted  products,"  continued Ms. Broadbent.
"Our  co-promotion  agreements  with  Merck,  Novartis  and Sirius  Laboratories
expired in accordance with their terms or were mutually terminated at the end of
2003, which accounts for the drop in contract revenues from the first quarter of
2003 to the first quarter of 2004. We are in discussions with several  potential
marketing  partners to add new products to our  portfolio,  and our formation of
dedicated dental and dermatology sales forces has been viewed very positively by
these potential partners."

     CollaGenex  continued  its  commitment to research and  development  in the
first  quarter of 2004.  "We  invested  in our  pipeline by  increasing  our R&D
spending  compared to the first quarter of 2003 by about $366,000,  or more than
35%,  primarily  to  fund  the  clinical  development  of  Periostat  MR and the
development of products based on our Restoraderm(R) technology platform. This is
consistent  with our stated plans to increase our investment in the  development
of our  proprietary  product  pipeline.  We anticipate  our total R&D investment
during 2004 to be in the range of $8.5 to $9.0 million  compared to $5.5 million
in 2003," continued Ms. Broadbent.

     As  previously  announced,  the  License and Supply  Agreement  with Mutual
provides  for the  shipment  during  the  second  quarter  of 2004 of an initial
stocking order, including a one-time promotional  allowance.  CollaGenex expects
this to affect its  quarterly  sales  patterns  and  profitability  during 2004.
Thereafter, the Company anticipates that reported sales will be primarily driven
by end-user demand.

     CollaGenex  Pharmaceuticals,  Inc.  is a specialty  pharmaceutical  company
focused on providing  innovative medical therapies to the dental and dermatology
markets. Currently, the Company's professional dental pharmaceutical sales force
markets Periostat,  which is indicated as an adjunct to scaling and root planing
for the  treatment  of adult  periodontitis.  Periostat  is the  first  and only
pharmaceutical  to treat  periodontal  disease by  inhibiting  the enzymes  that
destroy  periodontal  support tissues,  and by enhancing bone protein synthesis.
The dental  sales  force also  promotes  Atridox(R),  Atrisorb  FreeFlow(R)  and
Atrisorb-D FreeFlow(R), Atrix Laboratories, Inc.'s products for the treatment of
adult   periodontitis,   to  the  dental  market.  The  Company's   professional
dermatology sales force markets Pandel(R), a prescription topical corticosteriod
licensed from Altana, Inc.

     Research  has shown that certain  unique  properties  of the  tetracyclines
discovered  during the  development of  Periostat(R)  may be applicable to other
diseases  involving  inflammation  and/or  destruction of the body's  connective
tissues,  including acne,  rosacea,  meibomianitis and cancer metastases,  among
others.  CollaGenex  is  further  evaluating  Periostat(R),  as  well as the new
IMPACS(R)  compounds,  to assess  whether  they are safe and  effective in these
applications.   In  addition,   CollaGenex   has  licensed  the   Restoraderm(R)
technology,  a unique,  proprietary  dermal drug  delivery  system,  in order to
develop a range of topical  dermatological  products with enhanced pharmacologic
and cosmetic properties.
