FOR IMMEDIATE RELEASE

           NASTECH ANNOUNCES FOURTH QUARTER AND 2003 FINANCIAL RESULTS

    -CASH AND INVESTMENTS GROWS 278% AND R&D SPEND GROWS 47% FROM PRIOR YEAR-

BOTHELL, WA, MARCH 10, 2004 -- Nastech Pharmaceutical Company Inc. (Nasdaq:
NSTK), today announced a net loss of $5.9 million, or $0.50 per share for the
quarter ended December 31, 2003, compared to a net loss of $5.8 million, or
$0.57 per share for the fourth quarter of 2002. Total revenue for the fourth
quarter of 2003 was $911,000, a decrease of $846,000 from the fourth quarter of
2002. This decrease in revenue was partially offset by a $606,000 decrease in
operating expenses. Comparing expenses in Q4-2003 to Q4-2002, research and
development expense grew $2.3 million due to clinical trials and other
expenditures in support of our R&D programs, general and administrative expense
decreased $1.6 million and sales and marketing expense decreased $662,000.

Net loss for the full year 2003 was $2.1 million, or $0.20 per share, compared
to a net loss of $13.5 million, or $1.34 per share, for 2002. For 2003, total
revenue was $19.4 million compared to $8.9 million for 2002. The increase in
revenue for 2003 resulted primarily from a divestiture agreement with Pharmacia
under which Nastech reacquired all rights to Apomorphine Nasal Spray for Sexual
Dysfunction, and thereby recognized $16.3 million in connection with the
divestiture and collaboration agreements, compared to $7.4 million related to
the collaboration agreement in the same period of 2002.

Nastech ended 2003 with $25.1 million in cash, cash equivalents and investments
compared to $9.0 million at December 31, 2002.

"During 2003 and early 2004, we accelerated our most advanced and nearest-term
commercialization opportunities, including Calcitonin Nasal Spray for
osteoporosis, Apomorphine Nasal Spray for sexual dysfunction, and PYY Nasal
Spray for obesity," stated Steven C. Quay, M.D., Ph.D., Chairman, President, and
Chief Executive Officer. "The significant improvement in our working capital as
compared to the end of 2002 will help us achieve our near-term operating goals
for these important programs."

RECENT CORPORATE HIGHLIGHTS

    -   PYY 3-36 Nasal Spray for Obesity

In January 2004, Nastech initiated a Phase I-B dose-range finding study in
overweight healthy subjects. Today, the Company announced the successful
completion of this Phase I-B study. Results indicate that PYY significantly
reduces appetite, and significantly reduces calorie intake both at the lunch
meal 60 minutes after administration as well as for the entire 24-hour period.
PYY administration was well tolerated, with an acceptable side effect profile.
Detailed findings from this study will be discussed on today's conference call.

    -   Apomorphine Nasal Spray for Sexual Dysfunction

Today, Nastech announced that its Phase II Maximum Tolerated Dose clinical trial
reached completion and the results identify a dose that is safe and well
tolerated that is significantly above doses demonstrated in prior studies to
produce efficacy in erectile dysfunction. The results of this study support
moving forward with this sexual dysfunction clinical development program.




Detailed findings from this study will be discussed on today's conference call.
Nastech will seek a commercialization partner for this program before commencing
Phase 3 clinical trials.

    -   Calcitonin Nasal Spray for Osteoporosis

Nastech's ANDA filing was accepted for review by the FDA in February 2004.
Nastech is seeking a commercialization partner for this product.

    -   Tight Junction and siRNA Technologies

In February 2004, Nastech received a world-wide, non-exclusive license to the
Fire et al. patents and patent applications titled "Genetic Inhibition by
Double-Stranded RNA" (including U.S. Patent # 6,506,559 B1) from the Carnegie
Institute of Washington, D.C. Nastech is using small interfering RNA (siRNA)
technology in its tight junction research and to develop therapeutics based upon
siRNA technology. The Company will discuss its research programs in these areas
on today's conference call.
