     Entropin, Inc. ("Entropin") issued the following press release on
January 16, 2002:

                    ENTROPIN PROVIDES BUSINESS UPDATE

   INVESTOR CONFERENCE CALL TO BE HELD TODAY AT 4:30 P.M. EASTERN TIME

INDIO, Calif. (January 16, 2002)  - Entropin, Inc. (Nasdaq: ETOP, ETOPW) is
a specialty pharmaceutical company developing new topical therapeutics for
painful soft tissue injuries and diseases. Today, the Company will provide
an update on its progress toward developing and commercializing Esterom(R),
a revolutionary new topical drug.  Esterom(R) has the potential to replace
other current therapeutics for treating impaired physical function
resulting from painful soft tissue injuries and diseases - such as
tendonitis and bursitis of the shoulder and lower back sprain.

Entropin has scheduled an investor conference call regarding its progress
report. The call will be held today at 4:30 p.m. Eastern Time.  To
participate in the live call via telephone, please call (800) 355-7995 from
the U.S., or (212) 676-5009 for international callers.  A telephone replay
will be available until 6:30 p.m. Eastern Time January 18, 2002, by dialing
(800) 633-8284 from the U.S., or (858) 812-6440 for international callers,
and entering reservation number 20167040.

Those interested in listening to the conference call live via the Internet
may do so by visiting the Company's Website at www.entropin.com.  A replay
will be available on the Website for 14 days.

The topics to be discussed in the conference call include:

     *    Interim report of the Esterom(R) mechanism of action studies at
          Brigham & Women's Hospital at Harvard Medical School
     *    Filing of a patent application for enhanced manufacturing of
          Esterom(R)
     *    Selection of additional clinical sites for the Esterom(R) Phase
          II/III study
     *    Strategy to expedite patient enrollment in the Esterom(R) Phase
          II/III study
     *    Update of the clinical timeline for the Esterom(R) Phase II/III
          study

The Company has received an interim report of the mechanism of action
studies involving Esterom(R) and its various components being conducted in
the laboratory of Gary Strichartz, Ph.D. of the Brigham & Women's Hospital,
part of Harvard Medical School.  Dr. Strichartz is Professor of Anesthesia
and Director of the Anesthesia Research Laboratories and is a world expert
on pain and pain control.

For the first time outside of the Company's human clinical trials, the
potent analgesic effects of Esterom(R) have been demonstrated.
Specifically, Dr. Strichartz has shown that Esterom(R) effectively blocks
nerve impulse conduction and has long-lasting analgesic properties.
Furthermore, in testing the individual components that comprise Esterom(R),
Dr. Strichartz has shown that the hydroxypropyl esters of benzoylecgonine
are very potent in his models.  These

                                    2

molecules are 30- to 50-times more potent as analgesics than their non-
ester parent compounds, and are 5-times more potent than lidocaine, a
common topical anesthetic for local analgesia.  The studies further
demonstrated that a significant active component in Esterom(R) is a
molecule for which Entropin holds issued U.S. composition of matter
patents.

Dr. Strichartz stated, "These results demonstrate the essential
physiological actions among the separate components of Esterom(R), and
reveal the potential for long-lasting analgesia."

The Company also has filed a provisional application with the United States
Patent Office, entitled "Novel Benzoylecgonine Compositions and Methods for
Producing Them," which describes a manufacturing method for the enrichment
of the compounds covered in the Company's composition of matter patents.
The patent application describes a method for the production of Esterom(R).
If issued, the patent will strengthen and expand the Company's already
substantial patent portfolio for its lead clinical product.

Thomas G. Tachovsky, Ph.D., Entropin's president and chief executive
officer, commented, "The preliminary results of the mechanism of action
study confirm that Esterom(R) works.  We now have demonstrated in these
laboratory studies that the active ingredient(s) in Esterom(R) provides an
analgesic effect by disrupting nerve impulses.  We have already proven
Esterom(R) to be safe in previous trials with no serious adverse events,
and we expect the current Phase II/III study to prove its efficacy.  Our
intellectual property portfolio protects our market position for a
significant period of time, with several key patents extending through 2013
with further extensions possible.  Additionally, if issued, our new patent
will further extend the period of exclusivity for Esterom(R)."

Furthermore, the Company has added two new sites, Renstar Medical Research
in Ocala, FL and Renstar Medical Research in Plantation, FL, to the roster
of clinical sites participating in the Esterom(R) Phase II/III study.   The
principal investigators at these sites are part of large primary
care/general medicine practices and supplement the medical experts in
orthopedics, sports medicine and rheumatology currently in place.

On September 25, 2001, Entropin announced enrollment of the first patient
in the Company's Phase II/III clinical trial.  Due to slower-than-
anticipated enrollment during the first three months of the trial, in
addition to adding two new clinical sites, the Company has engaged a
Clinical Research Associate to facilitate the study and to accelerate
patient enrollment.  Print advertising is now being supplemented with radio
advertising and a website, www.painfulshoulder.com, to broaden the
potential patient base.  The radio announcement and website describe the
study and instruct interested potential patients to call a toll free number
for further information.

Based on current information, the Company expects enrollment in the Phase
II/III study to be completed in September 2002, thereby adding
approximately six months to the previously stated enrollment timeline.  The
Company does not anticipate any material financial impact due to this
delay.
