     Sucampo Will Begin Commercializing RESCULA in First Quarter of 2013

Business Wire

BETHESDA, Md. -- December 12, 2012

Sucampo Pharmaceuticals, Inc. (“Sucampo” or “the Company”) (NASDAQ: SCMP)
today announced that it has received approval of an sNDA for RESCULA^®
(unoprostone isopropyl ophthalmic solution) 0.15% for the lowering of
intraocular pressure (IOP) in patients with open-angle glaucoma or ocular
hypertension from the U.S. Food and Drug Administration (FDA). Open-angle
glaucoma is the most common form of glaucoma. Sucampo intends to commercialize
RESCULA in the first quarter of 2013.

According to the approved product labeling, RESCULA may be used as a
first-line agent or concomitantly with other topical ophthalmic drug products
to lower intraocular pressure. RESCULA is a BK (Big Potassium) channel
activator, which is different from other IOP lowering agents.

“RESCULA provides IOP reduction by increasing trabecular flow, and may be an
appropriate choice for eye specialists who are trying to balance efficacy with
management of side effects. It has been shown to be an effective medicine in
lowering IOP in patients with open-angle glaucoma and ocular hypertension
while demonstrating an excellent systemic safety profile and an established
ocular side effects profile,” said Ryuji Ueno, M.D., Ph.D., Ph.D., Chairman,
Chief Executive Officer, and Chief Scientific Officer of Sucampo.

About Unoprostone Isopropyl (RESCULA)

Unoprostone isopropyl is a member of Sucampo’s family of prostones and is a
synthetic docosanoid. Unoprostone isopropyl may have a local effect on BK (Big
Potassium) channels in the eye. BK channels are expressed in contractile
tissues like the trabecular meshwork. RESCULA may reduce elevated intraocular
pressure (IOP) by increasing the outflow of aqueous humor through the
trabecular meshwork. Complete details of the mechanism of action are unknown
at this time.

RESCULA was originally approved by the FDA in 2000 for the lowering of IOP in
open-angle glaucoma and ocular hypertension in patients who are intolerant of
or insufficiently responsive to other IOP lowering medications. In April 2009,
Sucampo acquired the commercialization rights to RESCULA for the United States
and Canada from R-Tech Ueno, Ltd. (RTU).

Important Safety Information

Contraindications

RESCULA is contraindicated in patients with hypersensitivity to unoprostone
isopropyl or any other ingredient in this product.

Warnings and precautions

Unoprostone isopropyl ophthalmic solution may gradually increase the
pigmentation of the iris. The pigmentation change is believed to be due to
increased melanin content in the melanocytes rather than to an increase in the
number of melanocytes. The long term effects of increased pigmentation are not
known. Iris color changes seen with administration of unoprostone isopropyl
ophthalmic solution may not be noticeable for several months to years.
Treatment with RESCULA solution can be continued in patients who develop
noticeably increased iris pigmentation. Patients who receive treatment with
RESCULA should be informed of the possibility of increased pigmentation which
is likely to be permanent.

Unoprostone isopropyl has been reported to cause pigment changes (darkening)
to periorbital pigmented tissues and eyelashes. The pigmentation is expected
to increase as long as unoprostone isopropyl is administered, but has been
reported to be reversible upon discontinuation of unoprostone isopropyl
ophthalmic solution in most patients.

RESCULA should be used with caution in patients with active intraocular
inflammation (e.g., uveitis) because the inflammation may be exacerbated.

Macular edema, including cystoid macular edema, has been reported. RESCULA
should be used with caution in aphakic patients, in pseudoaphakic patients
with a torn posterior lens capsule, or in patients with known risk factors for
macular edema.

To minimize contaminating the dropper tip and solution, care should be taken
not to touch the eyelids or surrounding areas with the dropper tip. Keep
bottle tightly closed when not in use. There have been reports of bacterial
keratitis associated with the use of multiple-dose containers of topical
ophthalmic products.

RESCULA contains benzalkonium chloride, which may be absorbed by soft contact
lenses. Contact lenses should be removed prior to application of solution and
may be reinserted 15 minutes following its administration.

Adverse reactions

In clinical studies, ocular adverse events above 5% with use of RESCULA were
burning/stinging (22.4%), burning/stinging upon drug instillation (18.6%),
itching (13.2%), injection (11.6%), dry eyes (10.7%), foreign body sensation
(9.0%), abnormal vision (8.2%), lacrimation disorder (6.2%) and eyelid
disorder (5.8%). Approximately 10-14% of patients were observed to have an
increase in the length of eyelashes (≥ 1mm) at 12 months, while 7% of patients
were observed to have a decrease in the length of eyelashes. Corneal lesions
were reported in 2.3% of patients.

The most frequently reported nonocular adverse event associated with the use
of RESCULA in the clinical trials was flu-like syndrome, observed in
approximately 6% of patients.

Use in specific populations

Pregnancy Category C - There are no adequate and well-controlled studies in
pregnant women. Because animal studies are not always predictive of human
response, RESCULA should be used during pregnancy only if the potential
benefit justifies the potential risk to the fetus.

Pediatric Use - the safety and efficacy of RESCULA in pediatric patients have
not been established.

It is not known whether RESCULA is excreted in human milk. Because many drugs
are excreted in human milk, caution should be exercised when RESCULA is
administered to a nursing woman.

No overall differences in safety or effectiveness of RESCULA have been
observed between elderly and other adult populations.
