         ENTROPIN UPDATES ESTEROM(R) PHASE II/III CLINICAL TRIAL
                           ENROLLMENT PROGRESS

INDIO, Calif. (March 27, 2002) - Entropin, Inc. (Nasdaq: ETOP, ETOPW), a
specialty pharmaceutical company developing new topical therapeutics for
painful soft tissue injuries and diseases, today updated enrollment
progress for its Phase II/III Clinical Trial of Esterom(R).

Entropin's President and Chief Executive Officer, Thomas G. Tachovsky,
Ph.D., commented, "Our Phase II/III study with Esterom(R) in treating
impaired range of motion associated with acute painful shoulder is well
underway.  A total of 57 patients are currently enrolled in our 150
patient Phase II/III Study.  Additional patients are being screened and
we continue to receive inquiries daily from individuals interested in
participating."

"We are pleased with the current pace of patient enrollment and continue
to be enthusiastic about the potential positive outcome of this study.
We expect to complete patient enrollment and report the results of this
study in the third quarter of 2002.  While we continue to anticipate the
need for at least one additional clinical study, we remain on track to
file a New Drug Application (NDA) for Esterom(R) in 2004," added Dr.
Tachovsky.

This study is examining patients between the ages of 18 and 65 years who
have a soft tissue affliction resulting in impaired function of the
shoulder. The prior Phase II study, demonstrated that Esterom(R) provided
statistically significant improvement for soft tissue afflictions for
both the shoulders and the lower back.

It is management's opinion that Esterom(R) has the potential to replace
other current therapeutics for treating impaired physical function
resulting from soft tissue injuries and diseases - such as tendonitis,
impingement syndrome, bursitis and lower back sprain, and possibly, forms
of arthritis.  Esterom(R) is Entropin's investigational drug for patients
suffering from these painful and limiting range of motion medical
conditions.
