     Entropin, Inc. ("Entropin") issued the following  press release on
October 17, 2001:

                              NEWS RELEASE
                              ------------

ENTROPIN EMBARKS ON COMPREHENSIVE INVESTOR RELATIONS PROGRAM

INDIO, Calif. (October 17, 2001) - Entropin, Inc. (NASDAQ: ETOP; ETOPW)
today reported that it has begun a comprehensive Investor Relations
Program. The goal of this campaign is to familiarize the investment
community with the progress Entropin is achieving in the development of
Esterom(R).  Esterom(R) is a revolutionary new topical drug which has the
potential to replace other current therapeutics for treating impaired
physical function resulting from painful soft tissue injuries and diseases
- such as tendonitis, bursitis and lower back sprain.

Entropin has begun a series of presentations that will include more than
twenty U.S. cities. Members of Entropin's executive management team will
meet with fund managers, brokers and analysts.  The Company is also
conducting an extensive direct mail program to inform the financial
community of the Company's progress.

The Company's presentation is based on publicly available information and
focuses on the unique characteristics of Esterom(R), the protocol design
for the current clinical trial, the Company's scientific, development and
research partners, as well as, Entropin's business strategy and its
development timeline for Esterom(R).

Entropin's President and Chief Executive Officer, Thomas G. Tachovsky,
Ph.D., commented, "Esterom(R) is a revolutionary new product with immense
potential.  We are enthusiastic about the anticipated outcome of our
current clinical trial and want to share our story with investors."  Dr.
Tachovsky went on to add, "Our goal is to reach a broad audience within the
investment community."

On September 25, 2001, the Company announced that it had begun its current
clinical trial.  This Phase II/III Study is a double blind, placebo-
controlled study designed to treat 150 patients for shoulder pain and
disability.  Non-placebo patients will receive treatments of 10% Esterom(R)
solution on three consecutive days with a seven-day follow-up period. The
study has clearly defined endpoints and will employ validated measurement
tools to determine the effect of Esterom(R) treatments.

The Company expects enrollment of the 150 patients to take approximately
six months.  Entropin has contracted with Medidata Solutions for state-of-
the-art on-line centralized data capture to provide real-time monitoring
and to shorten the time required to analyze the data when the study is
complete.  Based on the time required to recruit patients that meet the
study's diagnostic entry criteria, the Company anticipates releasing the
results of this study in the first half of 2002.
