September 5, 2012

MISSISSAUGA, ON, Sept. 5, 2012 /PRNewswire/ – Nuvo Research Inc. (TSX: NRI), a
specialty pharmaceutical company dedicated to building a portfolio of
products for the topical treatment of pain today announced that the
United States Patent Office has issued United States Patent #
8,252,838 relating to compositions and methods of using PENNSAID(®) (diclofenac sodium topical solution) 2.0% w/w (PENNSAID 2% Patent). 
The patent expires on April 21, 2028.

Nuvo’s U.S. licensing partner, Mallinckrodt Inc. (Mallinckrodt), the
pharmaceuticals business of Covidien, has advised Nuvo that the U.S.
Food and Drug Administration (FDA) had accepted a New Drug Application
(NDA) for PENNSAID (diclofenac sodium topical solution) 2.0% w/w for
review and set a Prescription Drug User Fee Act (PDUFA) date of March
4, 2013 for action on the submission.  Mallinckrodt will take the
necessary steps to have the new patent listed in the FDA Orange Book
upon FDA approval.

“We are very pleased that we have been able to secure additional patent
protection for PENNSAID 2%,” said Tina Loucaides, Nuvo’s Vice President
and General Counsel.  “This patent, together with our recently
announced method of use patent for PENNSAID and PENNSAID 2% gives us a
strong patent portfolio that will support the PENNSAID franchise.”

About PENNSAID 2%

PENNSAID 2% is the follow-on product to original PENNSAID, a topical
non-steroidal anti-inflammatory drug (NSAID).  PENNSAID 2%, which is
not approved by the FDA, contains 2% diclofenac sodium compared to 1.5%
for original PENNSAID.  It is more viscous than original PENNSAID, is
supplied in a metered dose pump bottle and is designed to be applied
twice each day compared to four times a day for original PENNSAID.  If
approved by the FDA, PENNSAID 2%, like PENNSAID, will be indicated for
the treatment of the signs and symptoms of osteoarthritis (OA) of the
knee.

     _____________________________________________________________________
    |Cardiovascular Risk                                                  |
    |                                                                     |
    |    --  Nonsteroidal anti-inflammatory drugs (NSAIDs) may cause an   |
    |        increased risk of serious cardiovascular thrombotic events,  |
    |        myocardial infarction, and stroke, which can be fatal. This  |
    |        risk may increase with duration of use. Patients with        |
    |        cardiovascular disease or risk factors for cardiovascular    |
    |        disease may be at greater risk.                              |
    |    --  PENNSAID is contraindicated in the perioperative setting of  |
    |        coronary artery bypass graft (CABG) surgery.                 |
    |Gastrointestinal Risk                                                |
    |                                                                     |
    |    --  NSAIDs cause an increased risk of serious gastrointestinal   |
    |        adverse events including bleeding, ulceration, and           |
    |        perforation of the stomach or intestines, which can be fatal.|
    |        These events can occur at any time during use and without    |
    |        warning symptoms. Elderly patients are at greater risk for   |
    |________serious_gastrointestinal_events._____________________________|

PENNSAID is contraindicated in patients:

        --  with a known hypersensitivity to diclofenac sodium or any other
            component of PENNSAID
        --  who have experienced asthma, urticaria, or allergic-type
            reactions after taking aspirin or other NSAIDs. Severe, rarely
            fatal anaphylactic-like reactions to NSAIDs have been reported
            in such patients.

Elevation of one or more liver tests may occur during therapy with
NSAIDs. PENNSAID should be discontinued immediately if abnormal liver
tests persist or worsen.

Use with caution in patients with fluid retention or heart failure.
Hypertension can occur with NSAID treatment. Monitor blood pressure
closely with PENNSAID treatment.

Long-term administration of NSAIDs can result in renal papillary
necrosis and other renal injury. Use PENNSAID with caution in patients
at greatest risk of this reaction, including the elderly, those with
impaired renal function, heart failure, liver dysfunction, and those
taking diuretics and ACE-inhibitors.

Should not be used in pregnant or lactating women and is not approved
for use in pediatric patients.

Anaphylactoid reactions may occur in patients without prior exposure to
PENNSAID. NSAIDs can cause serious skin adverse events such as
exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic
epidermal necrolysis (TEN), which can be fatal.

The most common treatment-related adverse events in patients receiving
PENNSAID were application site skin reactions including dry skin (32%),
contact dermatitis characterized by skin erythema and induration (9%),
contact dermatitis with vesicles (2%) and pruritus (4%). In a long term
safety study, contact dermatitis occurred in 13% and contact dermatitis
with vesicles in 10% of patients, generally within the first 6 months
of exposure, leading to a withdrawal rate for an application site event
of 14%.  Other common adverse events greater than placebo include:
dyspepsia (9%), abdominal pain (6%), flatulence (4%), diarrhea (4%) and
nausea (4%).

Do not apply to open wounds. Protect treated knee(s) from natural or
artificial sunlight. Topicals such as sunscreen and bug repellant may
be applied after PENNSAID treated knee(s) are completely dry. Avoid
contact of PENNSAID with eyes and mucous membranes. Wash and dry hands
after use.

Concurrent use with oral NSAIDs should be avoided unless benefit
outweighs risk and periodic laboratory evaluations are conducted.
