Apricus Biosciences Provides First Quarter 2013 Corporate Update

Company to Host Conference Call/Webcast Today at 9:00 AM ET

SAN DIEGO, May 10, 2013 (GLOBE NEWSWIRE) -- Apricus Biosciences, Inc.
("Apricus Bio" or the "Company") (Nasdaq:APRI) (http://www.apricusbio.com),
today provided an update regarding ongoing corporate activities and announced
that it expects to file its Quarterly Report on Form 10-Q for the quarter
ended March 31, 2013 with the Securities and Exchange Commission on Friday,
May 10, 2013. As previously announced, the Company will host its first quarter
2013 financial results conference call today, May 10, 2013 at 9:00 a.m. ET.

"Apricus Bio began 2013 with a newly focused corporate strategy aimed at the
commercialization, through partnerships, of its lead product Vitaros® for
erectile dysfunction ("ED") and the development of its lead product candidate
Femprox® for female sexual arousal disorder ("FSAD")," said Richard Pascoe,
Chief Executive Officer of Apricus Bio. "Since the beginning of the year, we
have made important progress in support of that goal, including the successful
divestiture of multiple non-core assets, streamlining of our operations to
better align them with our objectives, and advancement of our regulatory and
commercial strategy for Vitaros® and Femprox®. We continue to believe that the
greatest opportunity for shareholder value creation remains in the global
development and commercialization, through strategic partnerships, of these
lead assets."

Recent Corporate Developments

  *European approval decision for Vitaros® in Europe via the Decentralized
    Procedure ("DCP"). We are currently awaiting a decision regarding the
    approval of Vitaros^® in Europe via the DCP with The Netherlands serving
    as the Reference Member State ("RMS"). In April of 2013, Apricus Bio, in
    consultation with our European commercialization partners, submitted to
    the RMS our response to the Day 120 List of Questions ("LOQ"). This week,
    which marked Day 180 of the regulatory approval process, the RMS confirmed
    that the major nonclinical, clinical and clinical safety issues outlined
    in the Day 120 LOQ have been resolved. While the regulatory review
    process is ongoing, and we remain in active dialogue with the RMS on
    certain remaining matters included in the Day 180 response, we believe
    that the marketing approval process for Vitaros® in Europe remains on
    track for an approval decision on Day 210 of the process assuming there
    are no other interruptions in the review process. If Vitaros® is approved
    by the RMS, our commercialization partners will commence with the National
    Phase approvals in their respective territories. Once those approvals are
    secured on a country-by-country basis, marketing of Vitaros® can then be
    initiated in each country by our commercialization partners. In Europe,
    existing ED products generated over $1 billion in sales in 2012 and
    Apricus Bio believes that a significant portion of the market remains
    untreated or undertreated, which represents a significant commercial
    opportunity for Vitaros®.
  *Commercial Launch of Vitaros® in Canada.Vitaros® is approved in Canada,
    and Apricus Bio licensed Vitaros® to Abbott Canada for commercialization
    of the product in that territory. Abbott remains fully committed to a
    successful launch of the cold-chain version of Vitaros® in Canada in the
    shortest timeframe possible.Abbott is working with their contract
    manufacturer to optimize the product's shelf-life period, which is driven
    by specifications that are applicable only to the product that will be
    sold in Canada, prior to launching the product in that market. As a
    result of these ongoing developments, Abbott has confirmed that a Vitaros®
    launch in Canada in the first half of 2013 will not occur.
  *Femprox® Development Program:Femprox® is our lead product candidate for
    the treatment of female sexual arousal disorder, or FSAD.To date, we have
    completed seven clinical studies with Femprox® including a 100 patient
    Phase 2 study in the U.S. and a 400 patient Phase 3 study in China.The
    data generated from these studies strongly suggests that Femprox® has the
    potential to effectively treat FSAD in a female patient population where
    there are currently no available FDA approved treatment options.Moreover,
    we believe that Femprox® could be the first and only on-demand treatment
    approved for FSAD, where estimates of the market size are on par with that
    found in the erectile dysfunction market. The Company continues to advance
    the Femprox® development program in close consultation with our clinical
    and regulatory advisors.Our near-term goal is to seek confirmatory
    regulatory guidance from the U.S. FDA in the form of an End-of-Phase 2
  *Divestiture of Non-Core Assets: The Company sold its product, Totect^®
    (dexrazoxane HCl), a marketed, injectable treatment for anthracycline
    extravasation, to Biocodex USA ("Biocodex") in March 2013, in line with
    its recently updated corporate strategy. Under terms of the arrangement,
    Apricus Bio received an upfront payment at closing and is eligible to
    receive royalties on net sales of Totect^® by Biocodex through 2016, in
    exchange for Apricus Bio's sale of its commercialization rights to
    Totect^® in North America and South America.

About Vitaros®

Vitaros®, Apricus Bio's lead product candidate for the treatment of ED, is a
topically-applied cream formulation of alprostadil, a vasodilator, which
directly increases blood flow to the penis, causing an erection. Alprostadil
is a widely accepted alternative to the PDE5 inhibitors for difficult to treat
patients, and Vitaros® is relatively safe and effective, and offers greater
market opportunity due to its patient-friendly form versus both other
alprostadil dosage forms and also relative to oral ED products. With a market
affecting nearly 150 million men worldwide and representing approximately $2.6
billion in revenue – excluding the U.S. – Vitaros® represents a major market
opportunity, particularly as a distinct product that addresses a significant
underserved population.

About Femprox®

Femprox® is a product candidate for the treatment of female sexual arousal
disorder (FSAD).Seven clinical studies have been successfully completed to
date, including one, 98-subject Phase 2 study in the US and a nearly
400-subject Phase 3 study in China.To date, no product has been approved in
the U.S. to treat FSAD, a persistent or recurring inability to attain or
maintain adequate sexual excitement, causing personal distress.Estimates of
the FSAD market size put it on par with erectile dysfunction in males, and
possibly larger.
