                           PAIN THERAPEUTICS ANNOUNCES
                      SECOND QUARTER 2006 FINANCIAL RESULTS

SOUTH SAN FRANCISCO, CALIF. - AUGUST 9, 2006 - Pain Therapeutics, Inc. (Nasdaq:
PTIE), a biopharmaceutical company, today reported financial results for the
three and six months ended June 30, 2006. Net income for the quarter ended June
30, 2006 was $1.4 million, or $0.03 per share, compared to a net loss of $10.2
million, or $0.23 per share, in the second quarter of 2005. The net income for
the six months ended June 30, 2006 was $2.2 million, or $0.05 per share,
compared to a net loss of $18.8 million, or $0.43 per share, for the same period
in 2005.

Cash, cash equivalents and marketable securities were $205.3 million at June 30,
2006. Pain Therapeutics continues to expect its cash requirements for 2006 to be
$15 million, plus or minus 10%.

"We believe we're in strong financial shape and we continue to make solid
progress across our business," said Remi Barbier, Pain Therapeutics' president
and chief executive officer. "We are pleased with the continued advancement of
our existing pipeline and we continue to uncover attractive and affordable
potential in-licensing opportunities from top academic labs in the areas of pain
management and hematology/oncology."

Pain Therapeutics recently received a $5 million milestone payment from King
Pharmaceuticals, Inc., its worldwide strategic partner for Remoxy(TM), PTI-202
and two other abuse-resistant opioids painkillers. This was the first milestone
payment under the strategic alliance between the two companies. A total of up to
$150 million may be paid by King Pharmaceuticals to Pain Therapeutics,
contingent upon the achievement of regulatory and clinical milestones over the
course of the strategic alliance.

2006 FINANCIAL HIGHLIGHTS
- -------------------------

     o    We have a strategic alliance with King Pharmaceuticals, Inc. ("King")
          to develop Remoxy, PTI-202 and two other abuse-resistant opioid
          painkillers. Collaboration revenue of $7.2 million reflects actual and
          expected reimbursement from King of our collaboration expenses
          incurred during the second quarter of 2006.
     o    King gave us an upfront cash payment of $150 million in December 2005.
          For accounting purposes, we plan to recognize a portion of this cash
          payment as "program fee revenue" each quarter through mid-2011. We
          recognized program fee revenue of $6.6 million this quarter.
     o    On January 1, 2006 we adopted Statement No. 123(R), Share-Based
          Payment, or FAS 123R, as required by the Financial Accounting
          Standards Board. In adopting FAS 123R, we began to recognize employee
          non-cash stock-based compensation related expenses in our financial
          statements.
     o    Research and development expenses for the second quarter of 2006
          increased to $10.2 million from $9.5 million for the second quarter of
          2005. Research and development expenses for the six months ended June
          30, 2006 increased to $23.0 million from $17.6 million for the same
          period in 2005. The increase in research and development expenses for
          the second quarter was primarily due to the timing of the Phase III
          clinical trials for Remoxy and increases in development activities
          with Remoxy and other abuse-resistant product candidates as well as
          increases in non-cash stock related compensation costs associated with
          the adoption of FAS 123R.
     o    General and administrative expenses increased to $2.0 million from
          $1.1 million in the three months ended June 30, 2006 and 2005,
          respectively, and to $4.0 million from $2.2 million in the six months
          ended June 30, 2006 and 2005, respectively. The increases were
          primarily due to increases in non-cash stock related compensation
          costs associated with the adoption of FAS 123R.
     o    We have an income tax expense of $2.6 million for the three months
          ended June 30, 2006 that consists of the second quarter portion of
          currently estimated alternative minimum tax for 2006. Our income tax
          expense for alternative minimum taxes will fluctuate between quarters
          during 2006.

ABOUT PAIN THERAPEUTICS, INC. - ----------------------------- Pain Therapeutics is a biopharmaceutical company that develops novel drugs. We have three investigational drug candidates in clinical programs. Remoxy and PTI-202 are proprietary, abuse-resistant forms of currently prescribed opioid drugs. Oxytrex(TM) is a novel, next-generation painkiller that potentially offers less physical dependence than currently marketed opioid painkillers. These three drugs target different segments of the multi-billion dollar market to treat severe chronic pain, such as persistent low-back pain or pain due to advanced stages of osteoarthritis. The FDA has not yet evaluated the merits, safety or efficacy of our drug candidates. For more information, please consult our website: www.paintrials.com. OUR STRATEGIC ALLIANCE WITH KING PHARMACEUTICALS, INC. - ------------------------------------------------------ We have a strategic alliance with King Pharmaceuticals for Remoxy, PTI-202 and two other abuse-resistant opioid painkillers. In December 2005, King paid us $150 million in cash as an up-front payment. King is also obligated to pay us up to $150 million in cash based upon the successful achievement of additional clinical or regulatory milestones for Remoxy, PTI-202 and two other abuse-resistant opioid painkillers. King funds development expenses pursuant to the strategic alliance and is obligated to pay us a 20% royalty on net sales of drugs, except as to the first $1 billion in cumulative net sales, for which the royalty is set at 15%. In exchange, King received worldwide commercial rights to Remoxy, PTI-202 and two other abuse-resistant drugs developed under the strategic alliance.
