officer of Sucampo Pharmaceuticals. "We will

work closely with these regulatory agencies over the coming months to

address their questions during the review and approval process."

Pharmaceuticals continues to review marketing opportunities in other

parts of the world in order to build upon the current success of AMITIZA® in the United States.
About AMITIZA® (lubiprostone)
AMITIZA® (lubiprostone) is indicated for the treatment of Chronic Idiopathic

Constipation (24 mcg) in adults and for Irritable Bowel Syndrome with

Constipation (8 mcg) in women 18 years of age and older.
AMITIZA is contraindicated in patients with known or suspected

mechanical gastrointestinal obstruction. Patients with symptoms

suggestive of mechanical gastrointestinal obstruction should be

thoroughly evaluated by the treating physician to confirm the absence of

such an obstruction prior to initiating AMITIZA treatment.
The safety of AMITIZA in pregnancy has not been evaluated in humans.

AMITIZA should be used during pregnancy only if the benefit justifies

the potential risk to the fetus. Women who could become pregnant should

have a negative pregnancy test prior to beginning therapy with AMITIZA

and should be capable of complying with effective contraceptive measures.
Patients taking AMITIZA may experience nausea. If this occurs

concomitant administration of food with AMITIZA may reduce symptoms of

nausea. Patients who experience severe nausea should inform their

physician.
AMITIZA should not be prescribed to patients that have severe diarrhea.

Patients should be aware of the possible occurrence of diarrhea during

treatment and inform their physician if the diarrhea becomes severe.
Patients taking AMITIZA may experience dyspnea within an hour of first

dose. This symptom generally resolves within three hours, but may recur

with repeat dosing. Patients who experience dyspnea should inform their

physician.

Idiopathic Constipation, the most common adverse reactions (incidence >

4%) were nausea (29%), diarrhea (12%), headache (11%), abdominal pain
