with Sucampo assuming responsibility for the first $6 million in
development expenses. In addition, Takeda will become the marketing
authorization holder and will be responsible for all commercialization
and regulatory activities.

channel activator, indicated in the United States for the treatment of
chronic idiopathic constipation (CIC) in adults and opioid-induced
constipation (OIC) in adults with chronic, non-cancer pain (24 mcg
twice daily). The effectiveness in patients with OIC taking
diphenylheptane opioids (e.g., methadone) has not been established.

constipation (IBS-C) (8 mcg twice daily) in women 18 years of age and

Important Safety Information

  -- AMITIZA (lubiprostone) 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 healthcare provider (HCP) to confirm
     the absence of such an obstruction prior to initiating AMITIZA treatment.
  -- 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 HCP.
  -- AMITIZA should not be prescribed to patients that have severe diarrhea.
     Patients should be aware of the possible occurrence of diarrhea during
     treatment. Patients should be instructed to discontinue AMITIZA and
     inform their HCP if severe diarrhea occurs.
  -- 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
     HCP. Some patients have discontinued therapy because of dyspnea.
  -- In clinical trials of AMITIZA (24 mcg twice daily vs placebo; N=1113 vs
     N=316, respectively) in patients with CIC, the most common adverse
     reactions (incidence > 4%) were nausea (29% vs 3%), diarrhea (12% vs
     1%), headache (11% vs 5%), abdominal pain (8% vs 3%), abdominal
     distension (6% vs 2%), and flatulence (6% vs 2%).
  -- In clinical trials of AMITIZA (24 mcg twice daily vs placebo; N=860 vs
     N=632, respectively) in patients with OIC, the most common adverse
     reactions (incidence >4%) were nausea (11% vs 5%) and diarrhea (8% vs
  -- In clinical trials of AMITIZA (8 mcg twice daily vs placebo; N=1011 vs
     N=435, respectively) in patients with IBS-C the most common adverse
     reactions (incidence > 4%) were nausea (8% vs 4%), diarrhea (7% vs
     4%), and abdominal pain (5% vs 5%).
  -- Concomitant use of diphenylheptane opioids (e.g., methadone) may
     interfere with the efficacy of AMITIZA.
  -- The safety of AMITIZA in pregnancy has not been evaluated in humans.
     Based on animal data, AMITIZA may cause fetal harm. AMITIZA should be
     used during pregnancy only if the potential benefit justifies the
     potential risk to the fetus. Caution should be exercised when AMITIZA is
     administered to a nursing woman. Advise nursing women to monitor infants
     for diarrhea.
  -- Reduce the dosage in CIC and OIC patients with moderate and severe
     hepatic impairment. Reduce the dosage in IBS-C patients with severe
     hepatic impairment.
