FOR IMMEDIATE RELEASE:

        COVIRACIL(R)NDA FOR THE TREATMENT OF HIV DISEASE ACCEPTED BY THE
                          FOOD AND DRUG ADMINISTRATION

DURHAM, N.C., NOVEMBER 4, 2002 -- Triangle Pharmaceuticals, Inc. (Nasdaq: VIRS)
announced today that the U.S. Food and Drug Administration (FDA) has notified
the Company that its New Drug Application (NDA) for marketing approval of
Coviracil for the treatment of HIV disease has been accepted for filing. Filing
of the NDA is recognition by the FDA that the application is sufficiently
complete for review.

"We are very pleased with this notification," commented Daniel G. Welch,
Chairman and Chief Executive Officer of Triangle. He continued, "Consistent with
our previous guidance when we submitted our NDA, the FDA granted Coviracil a
standard review. This means that as early as the third quarter of 2003, we hope
to have our first NDA approved. We believe, once approved, Coviracil will offer
patients and physicians an important new medicine for the management of HIV
disease. We will now turn our efforts to completion of the review process with
the FDA to work towards the timely approval of Coviracil."

Coviracil is a potent, once-a-day Nucleoside Reverse Transcriptase Inhibitor
(NRTI). The NDA includes data from over 2,000 patients and is supported by two
pivotal trials, FTC-303 and FTC-301. Triangle expects to file a European
Marketing Authorisation Application (MAA) by December 31, 2002.

Triangle Pharmaceuticals, Inc. is a specialty pharmaceutical company engaged in
the development of new antiviral drug candidates, with a particular focus on
therapies for the human immunodeficiency virus (HIV) and the hepatitis B virus.
Triangle's proprietary drug candidates under development for HIV and/or
hepatitis B include Coviracil(R) (emtricitabine), amdoxovir (formerly DAPD), and

utilizing Dynavax' immunostimulatory sequence (ISS) technology. More information
about Triangle's portfolio, management and product development strategy is
available on Triangle's website.
