FOR IMMEDIATE RELEASE

ENTROPIN NAMES RANDALL L. CARPENTER TO BOARD OF DIRECTORS AND REPORTS ON
             PREPARATIONS FOR UPCOMING STUDY WITH ESTEROM(R)

INDIO, CA (FEBRUARY 5, 2001) --Entropin, Inc., a pharmaceutical research
and development company (Nasdaq: ETOP), today announced the election of
Randall L. Carpenter, M.D. to the Entropin board of directors. Dr.
Carpenter serves currently as the vice president of clinical research and
development for Adolor Corporation, a pharmaceutical company that develops
products to treat pain. The company also reported on progress in the
analysis of its Phase IIIA study of Esterom(R) and preparations for its
next clinical study.

RANDALL CARPENTER BOARD APPOINTMENT
"Randy is a great addition to our Board of Directors," said Higgins D.
Bailey, Ed.D., chairman of the board of Entropin. "His experience in
defining medical strategy and clinical development will be particularly
helpful in designing and conducting future studies with Esterom(R). His
in-depth clinical experience in pain management and anesthesia brings a much
needed expertise to the board and will be useful as we continue to build
the company."

Before joining Adolor in 1998, Dr. Carpenter was director of clinical
research at Astra USA and Astra Pain Control Sweden. His career includes 15
years of anesthesiology practice. Since 1998, he has been an adjunct
associate professor in the department of anesthesiology at Duke University
Medical Center in Durham, North Carolina and has held faculty appointments
in anesthesiology at other medical schools from 1985-1998.

                                   -2-

From 1979-1981 he served in family practice for the National Health Service
Corps in Idaho. Earlier, he held research fellowships and residencies in
anesthesiology at Virginia Mason Hospital and University of California, San
Francisco.  Dr. Carpenter's M.D. is from the University of Michigan Medical
School in Ann Arbor, as is his undergraduate training in microbiology.

Dr. Carpenter commented, "I am looking forward to serving as a Director of
Entropin.  Esterom(R) is a unique product and I am very excited about its
potential and the future of the Company".

UPDATE ON ESTEROM(R) CLINICAL DEVELOPMENT PLANS
Thomas G. Tachovsky, Ph.D., president and chief executive officer of
Entropin, also reported that Entropin has been busy with the detailed
analysis of data from the 362-patient Phase IIIA double-blinded, placebo-
controlled study of Esterom(R) solution in patients with acute painful
shoulder. The company has assembled an expert committee to assist with that
review and the design of the protocol for its next clinical study. The
committee includes two leading orthopedic surgeons, a noted sports medicine
expert, and a prominent rheumatologist.  Dr. Tachovsky commented: "These
experts, along with the members of our Scientific and Medical Advisory
Board, have been extremely helpful in the analysis of our Phase IIIA
results and the design of the protocol for our next study.  With their
input, we are addressing the deficiencies of the Phase IIIA study design".

Dr. Tachovsky also said that Entropin is preparing to meet with members of
the U.S. Food and Drug Administration during the first quarter of 2001 to
discuss the results of the Phase IIIA study and seek the Agency's counsel
regarding the design of the upcoming study.  After meeting with the FDA,
the company will complete its plans for the continued development of
Esterom(R) and provide investors with an update.

Entropin, Inc. is a pharmaceutical research and development company,
initially focused on the development of a novel topical therapeutic called
Esterom(R) solution which the company is developing as a treatment for
impaired range of motion associated with acute painful shoulder and acute
lower back sprain. The company recently completed a Phase III trial of
Esterom(R) solution in patients with impaired shoulder function, and plans
to initiate its next study in 2001.
